Expert Explains Why Motorists Don’t Need Large EV Batteries

Hans Eric Melin envisions electric automobiles parked on American roadways when he considers the waste of batteries. They resemble gas-powered engines except that they have a high rate of acceleration and can travel 400 miles without emitting any carbon, which is something that conventional automobiles couldn’t do.

The problem is that electric car batteries consume a significant amount of space as well as raw materials. The majority of drivers, however, would not utilize all the available power. When running errands or picking up the kids from school, the pack is typically idle or just partially utilized. Therefore, the batteries perform without using significant amounts of the valuable atoms of cobalt, lithium and nickel placed inside them.

Batteries have the capacity to power automobiles for 10 years or more, and because of the introduction of electric vehicles and the average vehicle growing larger by the year, recycling materials from old batteries may make a significant contribution. However, Melin’s advice is to start with less. To begin, he says, use the small batteries.

University of California, Davis professor Gil Tal asserts that at this stage of the adoption of EVs, when the emphasis has mostly been concentrated on boosting power and range, that approach is challenging to sell, particularly in the United States. And the fact that automakers are now keen to show off greater power and range is proof that battery technology has evolved, even though the majority of drivers won’t truly utilize that much battery. The biggest problem, according to Tal, is that Americans buy cars to fulfill their dreams, and if that occurs, they wind up purchasing more battery power than is necessary.

Undoubtedly, all electric vehicles emit lower carbon emissions than gas-powered vehicles. However, the size of the battery is important. According to Minvir, a battery with 30 kilowatt hours uses almost one-half as much carbon as a 60-kilowatt-hour battery. According to Melin, nearly five Nissan Leafs weighing 3,000 pounds less but traveling one-half the distance could have been built with the same amount of lithium as a Ford F-150 Lightning.

Readers expressed outrage when a recent New York Times op-ed questioned how frequently people made use of a battery range of 300 miles. Everyone seemed to have a regular, long-term commitment that rendered the argument in the article invalid. Melin claims that nobody wants to get stuck on a trip, which is pretty obvious. If they have the money, people can choose from a wide range of long-distance electric vehicles.

According to political scientist Riofrancos, significant innovations are essential. It is wise for more knowledgeable EV buyers to select small batteries while keeping an eye on their budgets. As a result, fewer materials will be required.

There are still ways Americans could do more to make the most of every electric battery. For instance, options include sharing vehicles or adopting new technologies that enable drivers to exchange various battery sizes in accordance with their needs. Both of these strategies are already common in China. According to Melin, the option of switching to small batteries is less of a hassle than switching from a truck to a car or still giving up on owning a car in favor of driving in a bus or riding an ebike, options that would significantly hasten the decarbonization of the future.

As the obsession with bigger and more powerful batteries continues, enterprises such as Kandi Technologies Group Inc. (NASDAQ: KNDI) are likely to respond to this demand and design more energy-dense packs for electric vehicles and stationary storage until demand shifts toward more minimalist versions.
