Study finds EV batteries could last 40% longer in real-world use

A study by Stanford researchers published in Nature Energy suggests that EV batteries could last 40% longer than laboratory tests indicate. Unlike lab tests, which use constant current, real-world usage involves dynamic charge and discharge cycles, which are gentler on the battery. The study, which tested 92 lithium-ion battery packs, found that dynamic cycles improve battery health. This finding may ease concerns about battery replacement costs, a key barrier to EV adoption. However, further research is needed to confirm these results.
