AI Customer Service6 天之前· New research from the SLAC-Stanford Battery Center suggests that electric vehicle (EV) batteries may last longer in real-world use than laboratory tests predict. Using data from
AI Customer ServiceImportantly, there is an expectation that rechargeable Li-ion battery packs be: (1) defect-free; (2) have high energy densities (~235 Wh kg −1); (3) be dischargeable within 3
AI Customer ServiceThis smart system has helped modern EV batteries last longer because it takes preventive action to reduce battery degradation. It keeps the battery cells in good condition and EV owners can have a dependable long-lasting vehicle. While lab tests are helpful, real-world data shows a clearer picture of EV battery life.
Onori and her colleagues determined, however, that this is not an ideal approach for predicting the life expectancy of EV batteries — a find of particular importance, since batteries still account for about a third the of price of a new EV.
Battery scientists and engineers have typically tested the cycles of new batteries in laboratories, using a constant rate of discharge, followed by recharge, the authors explained. They then repeat this approach many times to learn if a new design could benefit the battery’s longevity.
People no longer need to change EV batteries every few years. New improvements in battery chemistry, design, and management systems have made these batteries last much longer. Today’s EV batteries are tough and often last longer than the time most people own a car.
“You still generally have warranties that promise 70 percent state of health at eight years, but the degradation that we're seeing on those batteries is much less,” says Wallace. However, research so far has been based on how the car’s systems report the battery’s state of health.
Their discovery could help scientists to develop better batteries, which would allow electric vehicles to run farther and last longer, while also advancing energy storage technologies that would accelerate the transition to clean energy. The findings were published September 12 in the journal Science.
