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.

So, what do these athletes from all over the world competing in various different sports have in common? They all rely on steel to enhance their performance and keep them safe while they compete for the highest honors in their profession.

Here are some of the most prominent ways steel plays its part in winter Olympic sports:

Blades/Edges of Steel

Ice Hockey

Ice hockey is easily the main attraction of winter Olympics as hockey finals are usually the last events of the Games. The same can be said of para ice hockey as well. Athletes glide through the rink on specially-made sledges, or sleds, and have as much, if not more, full-contact than regular ice hockey.

There are several pieces of equipment that enable hockey players to perform at their best, including their skates and sleds. The deciding factor in the quality of skates comes down to the type of steel used in the blades, or runners. Harder types of steel are preferred for less wear and tear and so that athletes do not have to sharpen the blades too often.

That’s why most opt for stainless steel, for its high-strength, hard, ductile and corrosion-resistant qualities. For para ice hockey players, their sleds make or break the game, and materials like magnesium, high-manganese anti-vibration steel and stainless steel give them the edge they need.

Figure Skating

Blades on figure skates look similar to that of hockey skates, but are longer and heavier. Figure skate blades also have the thickest type of blades at 4 to 5mm. These blades were most commonly made of tempered carbon steel coated with chrome, but lighter materials such as stainless steel are becoming more common. At the professional level, many athletes wear skates with high-grade steels that are much more expensive than common skates. A distinct characteristic of these blades is the spiked front toe which gives figure skaters the traction they need for rigorous jumps and spins.

Short and Speed Skating

Like blades for hockey and figure skates, short track and speed skates are also made of stainless steel. Short track skates are slightly curved and shorter than speed skates, with slightly rounded backends for safety.

Speed skates are different from those for short track because the back-end of the blade is detached from the boot. this reduces friction and energy loss. Also, the detached blade allows the blade to remain attached to the ice longer than attached blades.

Skiing and Snowboarding

Steel also plays a crucial part in the construction of ski and snowboard edges. With high-quality steel, athletes can sharpen the edges more frequently, and sharp edges are crucial for carving and turning on snow. Edges are most commonly made of stainless steel, and they are inserted into the body of the ski or snowboard via “teeth” or T-shaped ridges. Most edges have a Rockwell 48 hardness.

Bobsled

There are several variations of bobsled events during the Olympics: 2-man, 4-man and women’s doubles. No matter how many people are on a team, each bobsled has a steel chassis or skeleton and four steel blades attached to the bottom of the sleds. Every team must use the same type of steel for blades used in competition. Much like a car, materials that make up the bobsled must be lightweight yet strong so the athletes have the freedom to steer through the track. During competition, sleds slide through at an average speed of 150 km/hr.

Luge

The luge is considered to be the most dangerous winter Olympic sport due to high speeds and sharp turns of the track. After push off in a seated position, the person or pair lies flat on their backs and steer the sleds with their bodies. Sleds have a pair of steel blades attached to the bottom. Olympic rules prohibit teams from heating the blades before competition as it would decrease friction against ice. Instead, athletes try to maintain the sharpest blades possible.

Skeleton

Opposite of the luge, skeleton athletes race flat on their stomachs, with no brakes. Instead of starting on the sled, the athletes have to sprint for about 40 meters before hopping on. All skeleton sled frames must be made of steel, and blades are usually made of high-quality stainless steel. As for all the “sliding” sports, there are strict rules for the size and weight of the sleds.

Stephen Zoepf is the executive director at the Center for Automotive Research at Stanford University.

To kick off the forum, Stephen Zoepf, executive director at the Center for Automotive Research at Stanford University gave a presentation called “Electric Vehicles: Adapting to a Changing Marketplace” to share his insights on what future markets will look like and implications for automakers, suppliers as well as consumers.  

Here are the key takeaways.

The Future is Going to Look Very Different

According to a report by RethinkX, an independent research group, 6 trillion U.S. passenger miles will be driven in 2030, up 50 percent from 2021. Of those miles, 95 percent will be driven in self-driving, electric and shared vehicles and only 5 percent of those miles will be driven by internal combustion engine (ICE) vehicles.

The report goes on to say that autonomous EVs (A-EV) will make up 60 percent of the U.S vehicle stock, and those vehicles will be part of a shared-mobility service. As more people start to share cars, the overall number of vehicles on U.S. roads will drop from 247 million in 2020 to 44 million in 2030.

The change is already happening. In 2016, shared-mobility companies such as Uber and Lyft drove 500,000 passengers per day in New York City, which is triple the number of passengers from 2015. Today, more and more automakers like Tesla and GM are also entering the shared-mobility market.

The findings illustrate a future where people drive more miles with fewer cars, which are fueled by electricity, and shared instead of owned. It’s a radical visualization of the future, but one that is driven by economic forces.

By 2021, shared vehicles will be 4 to 10 times cheaper per mile than private vehicles, and American households will save an average of USD 5600 every year by switching to shared EVs from cars fueled by gas, according to RethinkX.

Zoepf shared another report by ARK investment Management which echoes the finding above- in the next ten years, people will drive three times more kilometers using half the number of cars and the number of EVs on the road will increase 10 fold.

What It Means for Car Manufacturers and Suppliers

A shrinking vehicle fleet consisting of mostly EVs can only mean one thing: a major disruption to the current automotive market.  

Right now, the average lifecycle of a car in the U.S. is 11 years. However, the majority of a car’s total mileage is driven in its early years. It’s the same for shared vehicles, but they are driven about 80,000- 90,000 km per year, 10 times the distance of privately-owned cars. What this shows is a compression of the vehicle lifespan in its first 3 to 4 years.

These statistics pose critical concerns for automakers.

Will overall vehicle sales decrease in the coming future? According to Zoepf, that’s the wrong question to ask. Instead, automakers should be asking “will I make money?” Automakers have a couple of choices. They can either adapt early on and manufacture EVs and/or A-EVs at a competitive price, or become a shared-mobility provider. Early movers such as Tesla, GM and Volvo are already shifting their business strategies to fit these models.

Another question to ask is how these trends will affect vehicle design. With shortened vehicle life-cycles, manufacturers can either design cars to last only 3 to 4 years for quick replacements, or opt for the aviation model where the vehicle will be built to last, but the interior parts, such as seats, will be replaced frequently. Whatever route manufactures choose to take, gaining a competitive edge in vehicle and service quality early on will be key.

What Will This Mean for Vehicle Material Suppliers?

If building cars to last is no longer a primary priority, will car makers downgrade their materials? The short answer is not a chance.

Through a customer survey study Zoepf conducted of 60,000 Zipcar customers, he showed that the number one factor when choosing a car is safety. However, there is no one, ideal model or type of car that is preferred in a shared mobility framework. The purpose of the trip determines the type of vehicle, and the success of a shared mobility service provider will depend on the variety of cars it can provide – all with competitive safety ratings.

The supplier’s role will be to continue providing high-quality materials that can boost the safety and cost competitiveness of future vehicles. Steel suppliers have to keep developing lightweight and high-strength steels like POSCO GIGA STEEL, and research new materials that can boost the competitiveness of EVs such as POSCO’s Hyper NO for motor cores, battery materials and POSCO ICT’s EV charging service and infrastructure.

There remain numerous challenges that lie ahead for a greener and safer future with EVs and A-EVs, and it might take longer than experts predict for lawmakers, corporations and consumers to all agree on an optimal mobility model. However, change is already underway and automakers and suppliers alike need to strategize and adapt early on to take advantage of the upcoming opportunities.
