Stanford study makes surprising discovery about electric vehicle batteries — here's what it means for EV owners
Scientists out of Stanford University's SLAC-Stanford Battery Center have found that electric vehicle batteries may last much longer than previously thought. In their new study, published this December in the journal Nature Energy, researchers found that the common way EV batteries have been tested — by quickly repeating a cycle of steady battery drain, followed by immediate recharging — may underestimate these batteries' lifespans. For this study, the researchers tested a number of batteries under real-world driving conditions, such as heavy traffic, freeway driving, and long stretches of being parked. They found that the more a test mimicked real-world situations, the longer a battery lasted. In fact, these tests showed some batteries "could last about a third longer than researchers have generally forecast," according to the Stanford Report. "We've not been testing EV batteries the right way," Stanford professor and study author Simona Onori told the Stanford Report. "To our surprise, real driving with frequent acceleration, braking that charges the batteries a bit, stopping to pop into a store, and letting the batteries rest for hours at a time, helps batteries last longer than we had thought based on industry standard lab tests." This is encouraging news for the growing number of drivers who use EVs for daily commuting. EV use has increased dramatically in recent years. In 2023, for the first time, more than 1 million battery EVs were sold in the United States. Globally, according to a report from the International Energy Agency, about 18% of all cars sold in 2023 were electric. The longer an EV battery lasts, the more benefits drivers can enjoy. For some, additional battery life means they will be able to own and drive the car for several more years. For others, it means they'll likely see higher resale values when they decide to move on from their current EV. Selling an EV involves some steps that are a little bit different from selling a gas-powered car. Common maintenance records for things like oil changes aren't relevant, but battery life absolutely is. A service like Recurrent can make that process easier and more lucrative for sellers. Not only does Recurrent connect sellers with dealers across the country, but it also monitors an EV's battery life, providing valuable information when selling your car. In fact, those who use Recurrent sell their EVs for an average of $1,400 more than those who don't. You can even compare your battery life to that of similar cars, which could give you another leg up when selling."It's not a competition — it's more like seeing, how's your battery doing compared to what it should be?" Recurrent CEO Scott Case told The Cool Down. "And if there are big problems, we can alert you and say, something's up with your battery."

Researchers discover certain driving behavior could impact the longevity of your car — here's what you need to know
While you would think wear and tear equals a loss, that's surprisingly not always the case with electric vehicles. An exciting new study from the SLAC-Stanford Battery Center revealed that forms of regular driving can increase the longevity of your EV's battery. CleanTechnica noted that traditional forms of battery testing have failed to replicate how we use batteries in real life. We don't always use a battery's energy completely before plugging it in. Simona Onori, the study's senior author and an associate professor of energy science and engineering at the Stanford Doerr School of Sustainability, explained the nuances of the study's battery testing to Stanford Report. "To our surprise, real driving with frequent acceleration, braking that charges the batteries a bit, stopping to pop into a store, and letting the batteries rest for hours at a time, helps batteries last longer than we had thought based on industry standard lab tests," Onori said. The U.S. Department of Energy stated that EV batteries have become a lot more reliable over their years of production as well. According to a recent study, EVs with model years of 2016 onward have a battery failure rate of 0.5% or lower. If you don't have an EV, getting one can be more cost-effective for you and can benefit the environment. Using an EV can save you money on fuel costs and maintenance such as oil changes. When you think about owning an EV, what concerns you most about public charging stations? Chargers not working Chargers not being available Charging being too expensive Charging taking too long Click your choice to see results and speak your mind. The DOE also stated that all-electric cars emit around 2,700 pounds of carbon dioxide a year, while gasoline-powered cars emit almost 12,600 pounds of CO2 annually. Of course, switching to a hybrid or plug-in hybrid car can reduce emissions as well. Any step away from using gas is better than nothing. Discoveries in battery production show that EVs have the potential to save even more money in the long run, and there is hope yet for recycling lithium-ion phone batteries for EVs.
