Why don’t more people drive EVs?

Electric vehicles (EVs) have a variety of benefits for drivers, the most obvious being cheaper electricity prices compared to gas. Not only that, EVs only have about a third of the parts of ICE vehicles, which results in maintenance-cost reductions by about 60 percent. There are also government subsidies that support EV manufacturers and consumers in numerous countries, and environmental regulations only look to strengthen. Despite all this, drivers have been slow to make the switch to EVs, and there are 3 critical reasons why.

1. Range

Today, EVs can travel about 200 to 400 miles on a single charge, and while this may be sufficient for most urban drivers, it’s still not enough coverage to relieve drivers of range anxiety. Low-capacity batteries are not the only problem – the weight of the car and the efficiency of the motor and converter also affect range. Put simply, even if a battery could hold more energy, it won’t result in increased range if the car is too heavy or the motor is inefficient and uses up too much energy. Automakers have to come up with comprehensive solutions to improve the battery capacity and motor efficiency as well as lightweight their vehicles.

2. Charging Time

EVs currently take up to several hours to fully charge, depending on the battery. Although there have been advancements in charging systems that allow for shorter charging times, the average charging duration cannot compete with the 3 to 5 minutes people spend at gas stations.

3. Charging Stations

Despite the technological leaps made in the development of EVs, charging infrastructure has not maintained the same pace. Gas stations outnumber charging stations in every country, and it will take time to figure out a model to commercialize charging stations and make the business more profitable.

Why EVs are still driving toward a bright future

Although there are still challenges to overcome, one of the greatest drivers of widespread EV adoption is national policy. A growing number of countries have declared they will limit or even ban ICE cars altogether by 2020. Policies are already in place to support a more environmentally sustainable auto industry, and companies are working hard to navigate and capitalize on the changing market environment.

This will bring about a wealth of new opportunities for related industries. That’s why automotive, materials, electronics and chemical companies around the world are investing heavily in technology to preempt this market, and first movers will gain a tremendous advantage.

POSCO is one of the companies looking to lead the global EV materials market and has been investing in and developing innovative solutions for EV manufacturers. POSCO has designed an ultra-lightweight yet strong chassis and developed the necessary parts to bring it to life. POSCO is also currently working with auto manufacturers, giving them access to POSCO’s EV chassis design expertise as well as its newly-developed materials.

CEO Kwon explores CES 2018

As such, CEO Kwon made his first official visit to the 2018 Consumer Electronics Show (CES) in Las Vegas earlier this month to stay on top of the latest trends in connectivity and smart solutions that can be applied to the manufacturing process in smart factories.

SEE ALSO: POSCO CEO Ohjoon Kwon Visits CES 2018

Ultimately, a smart factory for POSCO would entail using smart sensors to pick up data, smart analysis through AI and automated production processes. Moreover, the smart factory would store and analyze its big data and apply it to make future improvements and prevent malfunctions. Aligned with many of POSCO’s business growth engines, major topics and themes at CES 2018 included smart homes, smart cities, autonomous cars and AI, and more than 3,900 companies put forth their best innovations.

Smart Connectivity

As more and more cities undergo smart transformations, the next big trend will be data collection and analysis through 5G connectivity. It was no surprise to see numerous innovations in smart transportation, smart grid, public safety, healthcare, data analytics and more at CES 2018. Moreover, city officials from early-adapting cities such as Kansas City, Miami and Las Vegas took to the stage to discuss their cities’ smartization plans. Some of the topics discussed included using GIS mapping software, smart construction, inclusive technology and autonomous transportation to enhance citizens’ productivity, efficiency, safety and well-being.

CEO Kwon visited related booths to learn about new technologies POSCO could apply to its businesses. Currently, POSCO’s smart factories are run by POSCO ICT’s smart platform called PosFrame, which allows the factory to apply a digital genome map to operations via data collection, instantly convert smart factory initiatives in domains, act as a common platform for new technologies and apply the same, standardize smart factory model to other facilities through reusable software.

Also at this year’s CES, POSCO ICT signed an MOU with DPR Construction, a leading smart construction company to apply PosFrame to construction sites for more efficient, cost-effective and smarter construction processes.

Smart Transportation

Another major theme at this year’s CES was mobility. Namely, autonomous and electric mobility. Companies from all across the board from traditional car manufacturers and software companies to gaming companies lined up to showcase their new innovations.

Even as the market for sustainable EVs and autonomous EVs look to expand in 2018 and beyond, EVs only make up about 1 percent of the global fleet of cars and there’s still a ways to go before EVs become the norm. Drivers need to feel safe in their EVs or autonomous EVs, want greater range on a single charge and need to see more charging infrastructure in their communities before making the switch.

SEE ALSO: Ask an Expert: Electric Vehicles and the Future of the Automotive Market

What’s more is that just because a vehicle runs on electric batteries, it doesn’t automatically mean the vehicle is eco-friendly or transmits less harmful emissions. Manufacturers and consumers alike have to take a lifecycle approach to assess the car’s impact on the environment from production to end of life recycling.

POSCO works with numerous partners to develop leading solutions for electric vehicles.

That’s why POSCO is working with automakers to come up with vital solutions in the auto industry for a greener future. It supplies partners with an advanced high-strength steel (AHSS) called POSCO GIGA STEEL that is both lightweight and super strong, allowing cars to travel with less energy without compromising passenger safety.

POSCO is also a lithium provider and has developed an innovative technology to speed up the extraction process, saving time, costs and damage to the environment. It also works with car makers to apply premium electric steel to partners’ electric motors to increase efficiency and cut costs.

With so many exciting new innovations and technologies surrounding EVs, POSCO will undoubtedly play a significant role in ensuring automakers have the tools they need to realize a green future.  POSCO will work to stay ahead of newly emerging technologies to enhance the efficiency, sustainability and performance of all of its solutions.

1. #Winning – competitiveness and sustainability

POSCO was recently named the world’s most competitive steelmaker for the eighth consecutive year by World Steel Dynamics (WSD). POSCO again took home the gold with the highest scores in five categories including innovative technology, cost reduction, skill level of labor, restructuring and investment environment.

POSCO is the world’s most competitive steelmaker.

Not only did POSCO come out on top for competitiveness, the company was ranked 35th among the “Global 100 Most Sustainable Corporations in the World in 2017,” by Toronto-based magazine and research firm Corporate Knights. The list was announced in early 2017 at the World Economic Forum in Davos, Switzerland. This is the third consecutive year POSCO made the list with outstanding scores in safety, environment and the salary levels of employees.

2. Joining the trillion club

POSCO entered the trillion club twice in 2017 as it recorded USD 1.283 billion (KRW 1.365 trillion) of operating profits in the first quarter, and USD 1.0581 billion (KRW 1.1257 trillion) in the third quarter based on its consolidated operating profit. Even in the midst of global oversupply and governments opting for protectionist policies, POSCO’s profits were unscathed. Much of the credit is owed to the company’s steel and non-steel affiliates overseas with strong sales performances. The consolidated debt-to-equity ratio was the lowest since 2010 and the non-consolidated debt-to-equity ratio was at its lowest ever.

POSCO recorded an operating profit over KRW 1 trillion in the first and third quarter of 2017.

To add, international credit rating agency S&P upgraded POSCO’s BBB-plus credit rating outlook to “stable” last February, and Moody’s also upgraded POSCO’s long-term corporate credit rating outlook to “positive” on October 26.

3. Everything’s bigger in…POSCO

Last June, after 102 days of repair, Pohang Blast Furnace No.3 became the world’s fifth-largest blast furnace. Its internal volume expanded from 4350㎥ to 5600㎥, allowing the super-sized blast furnace to put out 15,000 tons of molten metal daily. POSCO currently operates five super-sized blast furnaces, or blast furnaces sized 5500㎥ or larger.

More and more automakers are adding EVs to their fleet. (Source: Engineering and Technology)

While all this sounds promising for the environment, EVs don’t automatically translate into lower GHG emissions. According to World Auto Steel (WAS), the emissions from vehicle production will be greater than the amount of emissions from driving. As such, it is becoming increasingly important for manufacturers, policymakers and consumers alike to view material options by considering its life cycle assessment (LCA).

World Auto Steel Case Study

WAS conducted a case study in which they compared two popular lightweight materials for EVS; aluminum and Advanced High-Strength Steel (AHSS). The study followed the University of California Santa Barbara Automotive Energy & GHG Model (UCSB Model) for a comprehensive analysis of each material’s total energy use throughout its entire life cycle, from production to end of life recycling. For the study, WAS examined 1,000,000 BEVs of equal range that were made up of either entirely aluminum or AHSS.

BEVs made of AHSS require over 15 percent less energy than aluminum cars. (Source: World Auto Steel)

The study found that automakers can make over 17 percent more BEVs made of AHSS than aluminum BEVs with the same amount of energy. In other words, with the energy it takes to make 1 million aluminum BEVs, automakers can make 1.17 million AHSS BEVs.

Why is AHSS More Energy Efficient?

Aluminum production requires 8 times more energy per kilogram than steel production because the production process of aluminum is much more complicated and involves more steps than steel production. The aluminum BEVs in the study used up 30 percent more energy than those made from AHSS throughout its entire life cycle. Plus steel is 100 percent recyclable and can be reused almost indefinitely.

There are many sources of emissions output involved in the entire life cycle of a vehicle. (Source: World Auto Steel)

This poses a serious need to reexamine existing policies and regulations that only seek to reduce tailpipe emissions. By also taking into account emissions from the production of materials all the way to how a car is disposed at the end of its life cycle, automakers can grasp a better picture of the real impact of their choices on the environment.

A Sustainable Choice

As a solution-providing partner for automakers, steelmaker POSCO designed the perfect AHSS for cars that is lightweight, extremely strong, highly formable and environmentally friendly. POSCO GIGA STEEL belongs to the highest category for tensile strength of greater than 1GPa (Gigapascal). It can withstand more than 100 kg of force per square millimeter, making it 3 times stronger than aluminum. It is also 3.5 times cheaper than aluminum and 2.1 times cheaper to manufacture.

SEE ALSO: Infographic: Driving the Future with POSCO GIGA STEEL

POSCO GIGA STEEL is three times stronger than aluminum.

In 2016, POSCO sold 9 million tons of steel sheets for cars, making up 10 percent of the entire global automotive market for steel sheets. POSCO GIGA STEEL was designed to further improve the performance and efficiency of POSCO’s auto partners around the world. As the auto industry heads towards a future where environmentally-friendly EVs become the norm, POSCO will strive to equip its auto partners with the materials and tools necessary to stay ahead and competitive.

However, implementing autonomous transportation systems is no easy task, from perfecting the technology to sorting out legal matters. Take a look at these 6 early-adapting cities around the world that have embarked on the road to driverless transportation systems.

Singapore

Last year, the city-state became the first in the world to launch an automated taxi service. While many companies such as Uber have been testing driverless taxi systems, no one has launched a working model yet. Singapore’s autonomous taxi service launched by nuTonomy only has six cars, but the company has plans to have a full fleet of driverless taxis on Singapore roads by 2018. For now, the fleet consists of modified Renault Zoe and Mitsubishi i-MiEV electrics that have an emergency driver at the wheel and researchers who ride in the back to gather data. The service is expected to drastically reduce the number of vehicles on Singapore’s congested roads.

Los Angeles

After much delay, city officials finally made it legal to test driverless vehicles in L.A. this year, and by 2020, the city could have fully autonomous vehicles operating on its roads. So far, 43 companies such as General Motors, Apple and Uber have testing permits in California, which means that a driver must be at the wheel, prepared to take over in case of an emergency. The Department of Motor Vehicles will finalize the rules and regulations surrounding autonomous vehicle testing in 2018. Autonomous transportation is a sector that will continue to generate much investment, and L.A. was already losing business to other cities in the U.S. due to its regulatory restrictions. With the new guidelines in place, the city can expect to be bustling with startup activity and innovative solutions to its transportation challenges.

For now, L.A. law requires drivers at the wheel of every autonomous vehicle. (Source: Los Angeles Times)

Munich

Germany is home to the most advanced automakers in the world, and in August 2017, German lawmakers drew up the guidelines for operating autonomous vehicles. Under the new guidelines, all autonomous vehicle software must be programmed in such a way that human life will be protected at any cost, over animals and property. Germany’s Transportation Ministry is the first in the world to draw up such guidelines for automated driving, and wide-implementation of autonomous transportation is expected to follow, starting with Munich.

Recently, Munich Airport launched an autonomous shuttle service that links Terminal 2 to a new infield satellite facility with an underground train. The trains are called INNOVIA Automated People Mover (APM) 300 and were built by Bombardier. The train tunnel is 382 meters and will have the capacity to move 10,900 passengers every hour in either direction.

Las Vegas

Las Vegas is another early-adapting city with plans to have autonomous transportation up and running throughout the entire city. However, the city’s first attempt at automated transportation ended badly when their automated shuttle bus collided with a semi-truck less than 2 hours after its debut. The cause of the accident was a delivery truck that backed into the bus. The shuttle was equipped with LiDAR sensors to map the roads. It was also fitted with cameras to identify obstacles on its path, and GPS locators for operators to locate the shuttle’s location. Despite the advanced systems, the city learned the hard way it cannot control what others do on the roads.

China’s Zhuzhou City

Many good things are happening in China in terms of autonomous transportation. Recently in Zhuzhou, an autonomous, caterpillar-like bus was spotted. The Autonomous Rail Rapid Transit (ART), was developed by CCRC, a Beijing-based company that deals with the supply of rail transit equipment. It moves along Zhuzhou roads via sensors and can travel up to 70km per hour on its electric batteries and is expected to cut carbon emissions and ease traffic congestion.

The ART looks like a cross between a bus and a train and glides through the city using sensors. (Source: Curbed)

London

In September, the UK’s first driverless bus was tested in London’s Olympic Park. Interestingly, residents, visitors and tourists were invited to take part in the test runs throughout the month of September, free of charge. Like other autonomous buses, this electric bus navigates the roads via sensors, cameras and GPS maps. So far, the tests have been successful and the city hopes to implement the buses throughout the city in the near future. Take a look at some of the initial reactions.

Going into 2018, companies such as Uber, General Motors and BMW are expected to continue investing in autonomous vehicles and ride-sharing services. As more and more cities fine-tune their regulations and guidelines surrounding such modes of transportation, the world should see driverless transportation options pop up in more places, with fewer errors, providing more sustainable transportation systems.

EVs will make up 54 percent of new car sales in 2040. (Source: Electrek)

Even though EVs make up about 1 percent of total new car sales in the U.S., EVs are on a steady, steep path upwards. According to a report by Bloomberg New Energy Finance, EVs will make up 54 percent of new car sales by 2040, and by 2029, EVs will be cheaper to buy than gasoline and diesel-fueled cars.

The figures are significant and will translate into a sharp increase in demand for rechargeable batteries and their materials.

The Evolution of EV Batteries

Before diving into the juicy details, it’s always helpful to cover the basics. Batteries are made up of 3 main components. The anode, or negative electrodes, the cathode, or positive electrodes and some type of electrolyte through which the electrodes travel to release chemical energy.

A simple battery can be made out of a potato, copper penny and galvanized nail. (Source: Tested)

The first rechargeable battery, lead-acid battery, was invented in 1859 by a physicist named Gaston Plante. Lead dioxide was the cathode material used, and lead was the anode material with a liquid solution of sulphuric acid and water as the electrolyte. The materials were affordable and the battery was applied to many early models of EVs, including early models of the Tesla Model S.

Another widely used battery that came after the lead-acid battery is the nickel-metal hydride (NiMH) battery developed at the Battelle-Geneva Research Center in 1967. Nickel hydroxide was used as the cathode material while a hydrogen-absorbing alloy was used as the anode material. A liquid solution served as electrolytes. The research for NiMH batteries was extensive, and funded jointly by Daimler-Benz and Volkswagen AG. The batteries were also applied to many EV models such as the Toyota Prius, prior to 2015.

The Advent of Lithium-Ion Batteries

The introduction of lithium-ion batteries was a game-changer. Sony first introduced them in 1991, and today, most EVs have them, including the Tesla Model 3. The batteries consist of lithium-cobalt oxide cathodes, graphite anodes and the electrolyte is usually a solution of lithium salt and an organic solvent, though some automakers are experimenting with solid-state electrolytes.

Compared to its predecessors, lithium-ion batteries have the highest amount of stored energy and specific power, which is kind of like horsepower for electric cars. As a result of improved technology and lower costs, lithium-ion batteries are projected to make up 70 percent of the total rechargeable battery market by 2025, which will be worth roughly USD 112 billion.

Good as Gold

It is estimated that every 1 percent increase of EVs in the auto market will result in an additional 70,000 tons of lithium demand LCE per year.

In 2016, Australia topped the list for the most lithium produced with 14,300 metric tons. China and Zimbabwe are also top contenders producing 2000 and 900 metric tons in 2016, respectively. Then, there are the South American countries of Argentina, Chile, and Bolivia, also referred to as the “lithium triangle,” and home to 75 percent of the world’s lithium supply.

Does that mean the world has enough lithium to fuel the cars of tomorrow? The answer is yes, but there aren’t enough mines to produce them. In order to prevent environmental damage and the exploitation of unprotected workers, lithium producers have to get smart about lithium mining and production.

POSCO’s Lithium Production  

Starting in 2010, POSCO and the Research Institute of Industrial Science & Technology (RIST) teamed up to develop a chemically based lithium extraction technology. The innovation cut down extraction time from up to 18 months down to between 8 hours and 1 month, delivering a purity rate of 99.9 percent. The recovery rate of lithium also increased to over 80 percent. POSCO is the world’s first corporation to commercialize the technology.

SEE ALSO: Lithium Rocks: POSCO at Forefront of a Green Energy Future

POSCO CEO Kwon Ohjoon holds lithium on his visit to PosLX, POSCO’s battery production factory in Korea.

It’s also at the heart of the lithium triangle. POSCO currently operates facilities in Chile’s Maricunga Salt Lake, Argentina’s Cauchari Salt Lake and Argentina’s Pozuelos Salt Lake, which alone will boost POSCO’s annual lithium production to 2,500 tons. POSCO also opened its first battery production plant in Korea earlier this year.  

The future of EVs is promising thanks to advancements being made in electric batteries, and there’s a lot at stake for the health and well being of future generations. Increasingly, the availability and costs of EV battery materials will play a vital role in market outcomes and widespread EV adoption. It is vital for companies like POSCO to provide abundant, sustainable and cost-friendly EV battery materials so automakers can continue to enhance the batteries of tomorrow’s cars.

So, what happened to the EVs of the past, and how can the world prevent them from going the way of the dodo bird for yet a second time in history?

The Golden Age of Electric Vehicles

The first EV hybrid car was made in 1901 by Ferdinand Porsche, and by 1917, 38 percent of the cars on US roads were EVs, 40 percent were steam-powered cars and the remaining 22 percent were gasoline-fueled.

At the time, horse-drawn carriages were the norm, and people were desperate to solve the “pollution problem,” meaning pollution in the form of horse droppings. Even then, EVs were seen as the solution for a clean environment, and from 1895 to 1920, 50 companies were producing EVs. However, gasoline-powered vehicles were also a viable option and increased in number along with EVs as more highways were built and people and goods started to travel greater distances.

EVs had an initial advantage over gasoline cars for several reasons. They were more environmentally friendly, or the exhaust didn’t give off an awful smell, were less noisy and easier to drive. The shortcomings of gasoline cars also played a factor. Gasoline cars had to be started manually, or “cranked,” every time, making them laborsome and even dangerous to drive. Although they had better range, gasoline cars also broke down more often. The tables quickly turned.

The Rise of Gasoline and Ford

The company that led the rise and dominance of gasoline cars was Ford and its Model T vehicles that sold for USD 650 versus EVs that sold for around USD 3000. When Ford mastered mass production with assembly lines, the company turned out 1,670,000 vehicles in 1923.

Another key turning point for gasoline cars was when Charles Kettering invented the electric ignition in 1915. Drivers no longer had to start their cars manually, one of the reasons gasoline cars were not popular, especially among women.

As more highways were built, there was a demand for greater range that EVs just could not meet, especially when gas stations were cheaper to build than charging stations. Plus, there was no standardized plug for different EV models. Later on, when gasoline cars came equipped with exhaust-control devices that reduced the amount of harmful emissions, people were sold and EVs could no longer compete. EVs made a short resurgence back in the 1970s due to the global oil crisis, but by the 1980s, EVs were almost obsolete.

Back to the Future

Today, it seems as if history is repeating itself. There is a sense of urgency worldwide to tackle the pollution problem – except this time it’s not horse droppings.

In ten years between 2005 and 2015, the number of EVs went from hundreds to a million. Then, in 2016, there was a 60 percent increase in the global number of EVs, and the numbers are projected to grow exponentially. Many countries are backing the switch to electric fuel through tighter regulations on emissions and even completely banning gasoline and/or diesel cars.

Despite the rapid growth, EVs still make up just 1 percent of the global fleet of cars. According to the International Energy Agency (IEA), there need to be 150 million EVs by 2030 and 1 billion by 2050 to contain global warming within 2 degrees Celsius.

For widespread EV adoption, manufacturers, suppliers and policymakers alike can pick up some hints from the past.

Takeaways

EV manufacturers of the past and present have not found a cure for drivers’ range anxiety. It’s a scenario that likely crosses the mind of any driver considering an EV; running out of juice with no charging station in sight.

A study by MIT shows that range anxiety is irrational because most people drive just 45 miles a day, well under the range of today’s EVs.

A well-organized charging infrastructure is vital not only for drivers with range anxiety, but also for car companies and those in the charging business. Charging equipment is costly and stakeholders need to know there will be enough demand to make a return on their investment, but drivers are more likely to make the switch after a charging ecosystem matures. The dilemma calls for a collaborative effort among automakers, policymakers and companies like POSCO.

POSCO ICT’s ChargEV

POSCO ICT is an IT and engineering company looking to relieve range anxiety and take a holistic approach to establishing a charging infrastructure in Korea for a greener future. In partnership with various automakers, businesses and the government, POSCO ICT set up more than 300 charging stations in Korea and oversees many more private charging stations within its network.

The charging ecosystem is run through an app called ChargEV where drivers can sign up to get real-time information about charging locations, make reservations and even pay for charges. ChargEV is also a platform for customer support and reporting accidents. In addition, partner companies such as shopping centers and hotels that are now equipped with charging stations stand to benefit from the EV network.

EVs are, once again, a major disruptive factor in the automotive market and the future of private transportation. This time around, the stakes are much higher than pungent streets. As more countries and companies commit to reducing harmful emissions, the number of EVs will likely continue to spike. However, if stakeholders can learn a thing or two from the past, it’s that establishing a holistic charging ecosystem will have as much of an impact on EV adoption as the technological advancements of the vehicles themselves.

Compared to the world’s very first cars, today’s cars are faster, stronger, safer and have more sophisticated designs. As alternative materials like aluminum are increasingly being used for car parts that were originally made of steel, some even refer to this trend as a “material war.”

“Material War” in the Auto Industry

Recently, various substitutes for steel have entered the picture and are being applied in commercial vehicles. The most commonly used materials are aluminum and CFRP (Carbon Fiber Reinforced Plastic).

Beginning in the 1930’s, aluminum was primarily used as a lightweighting material for race cars and the outer panel of a vehicle. On the day of the Eifel race, the Mercedes-Benz weighed over the maximum limit and in an attempt to resolve this, the white paint was stripped from the frame, leaving the car’s aluminum frame completely exposed. This is how the Benz got its famous nickname, the “Silver Arrows.”

Safety regulations were less strict then than they are today. If there was an accident, the outcome would most likely be a severe injury or even death. With the goal of increased protection, researchers began to use tubular frames made of chromium molybdenum steel in order to reinforce the rigidity of the vehicle.

As the 1970’s rolled around, CFRP, a material that was already being applied in the aerospace industry, made an appearance in Formula 1 and automotive researchers quickly began discovering its potential and value. Soon enough, CFRP was considered an ideal material for race cars.

The rapid implementation of new substitute materials in the motorsports industry set a precedent for the auto industry as well. In the early 2000s, Audi shocked the industry by presenting the A2 and A8, two vehicles with car frames that were made completely out of aluminum. In 2015, BMW created a large-sized sedan made of CFRP, which was only used in a limited number of cars. This stunned consumers and the industry yet again. As advances were made with aluminum and CFRP, it seemed that steel would inevitably lose its place in the automotive material industry.

However, those who believed that the age of steel was over forgot one thing: steel is constantly evolving. While it is true that aluminum and CFRP could replace steel and that they are lighter, the disadvantages that come with these materials confirm that steel is a much more efficient material.

Aluminum

Aluminum, for example, is lighter than steel, but because it has less strength, thicker pieces need to be used. In order to achieve the same level of strength as steel, it needs to be mixed with other materials. Also, aluminum has a low melting point and easily leads to the formation of the oxide film, a factor that makes it difficult to weld. The high thermal conductivity makes the heat that is produced at the time of welding spread, making the material more brittle.

These disadvantages mean aluminum has to be welded in other ways such as riveting, a method of mechanical joining using thick mushroom-shaped nails or adhesive. If the aluminum is not tightly joined during the riveting process, oxide films form in between the cracks resulting in fatigue failure. If a tackifier was used in the process, an impact or collision could easily rupture the adhesive lining. Addressing these problems, while also ensuring that the frame is durable and light, has proved to be a much more expensive process than manufacturing a traditional steel car frame.

As such, numerous factors including durability, safety, and efficiency must be considered when choosing a material to be applied to a car.

From the 1930s to the ‘70s, it was possible to use aluminum in race cars because the vehicles were only used for one or two races. The aluminum pieces were hammered into shape by hand or joined together by rivets, but mass production of aluminum car frames was a very difficult operation. To this day, aluminum is still a difficult material to work with due to its high cost and the complicated technology involved in the production process.

CFRP

CFRP, which is known to be lighter and stronger than steel, also has several issues. Although a method for mass production has recently been established, it requires a much longer production time (the time allowed for one product to be produced) for a car body or shell, meaning that it also yields higher labor costs.

The McLaren MP4/1 was the first car frame to be made from CFRP.

Recently, Boeing and BMW began to research ways to recycle CFRP, but unlike steel or aluminum, it is fundamentally impossible to melt CFRP and give it a “new life”. Another reason why it is not an eco-friendly material is that various chemical products are used in the manufacturing process.

Also, 80% of carbon fiber production, one of the core materials in CFRP, is used by the aviation industry. Because the demand is much higher than the supply, it is much more expensive than steel and has yet to fully make its way into the automotive industry.

Because these shortcomings have not been addressed, researchers have started to turn their eyes back to steel. Even Audi, which once considered its aluminum car frames a major strength, has adopted steel to create the car frame for their newest sedan. Other major automakers still continue to look to steel as the main material as well.

The Shift Back to Steel

The reason for the shift back to steel is because it not only addresses certain disadvantages of alternative materials but also because it is a more affordable choice. The launch of POSCO GIGA STEEL and PosM, in particular, introduced a whole new level of steel.

Audi has turned away from a fully aluminum car frame and has begun incorporating high-tensile steel plates, as indicated by the purple portions of the car frame.

[clickToTweet tweet=”PosM is POSCO’s unique brand of steel that goes beyond the limits of traditional steel plates and exhibits a new level of performance.” quote=”PosM is POSCO’s unique brand of steel that goes beyond the limits of traditional steel plates and exhibits a new level of performance.” theme=”style6″]

PosM includes three different series of steel. The “E Series” focuses on elongation, the “Y Series” focuses on the yield strength and the “B Series” balances the benefits of the two.

The highlighted parts represent the parts that have been applied to the “E Series” of PosM

PosM “E Series”

The “E Series” was once thought to be only theoretically possible and has long been known as a dream material amongst the world’s leading steel companies. This is because it can meet two demanding conditions at once: strength and formability.

Not only does it have 2-9 times more processability compared to existing materials, it also has an excellent ability to absorb impact, which can make a car safer when used in those engine room parts that absorb and disperse impact.

Many steel companies attempted to produce this material but were not able to complete it due to difficulties in production. However, in 2008, POSCO successfully developed this material for the first time and made it available for purchase.

The highlighted parts represent the parts that have applied the “Y Series” of PosM.

PosM “Y Series”

The “Y series” is used for the parts of a car that protect the passengers, especially because of the yield strength, which represents the strength of a material until it becomes deformed, is quite high. This includes, for example, filler parts that prevent the passenger compartment from becoming damaged in the event of a collision.

PosM “B Series”

The “B series” has both the benefits of the “E series” and “Y series”. It is one of the best materials that can be formed by cold forming, which is a simpler process than what is used to make Hot Press Forming (HPF) steel. Because it is easy to process, it can be manufactured into complex shapes and yield a much lower processing cost.

Until now, there has never been a steel that could exhibit both high strength and durability like PosM has. PosM, first developed by POSCO in 2016, is an indispensable material for automobiles.

Through PosM, which exhibits next-level performance compared to existing advanced high-strength steel solutions, steel is once again being considered as an essential material in automobiles. Also, POSCO GIGA STEEL is rapidly advancing to meet the needs of today’s evolving industry, leading the advanced strength steel market.

POSCO GIGA STEEL, with outstanding processability, affordability and a tensile strength that is over three times that of aluminum with the same thickness, will continue to be a very important material in electric vehicles (EVs) which define the present and future of the automotive industry. It will help overcome the limits of batteries used in EVs and allow the vehicle to travel longer distances with its lightweight qualities and make the car body safer by satisfying the most stringent of safety standards.

In addition, the advantage of being more economical, cleaner and easier to recycle than other materials is necessary for an age where consumers value eco-friendly solutions. As long as cars exist, steel will always be one of the most important materials. Various manufacturers are already turning their attention to hybrid car frames that utilize a combination of aluminum, magnesium and carbon composites, with steel as the main focus.  As advanced high-strength steel continues to make improvements it has the potential to replace the need for these other materials altogether.

Automobile development continues to move forward with steel, and at the crux of this progress is POSCO GIGA STEEL.
