“Keeping your battery at elevated State-of-charge (high battery percentages) will definitely be detrimental to lifetime… Intuitively, at high state of charge, your battery stores the most energy, so [it] is more prone to side reactions and thus degradation,” Geslin said.

A new study suggests EV batteries could last far longer than previously estimated. One of the study’s authors said “We’ve not been testing EV batteries the right way” as they don’t factor in real-world driving conditions.

The shelf-life of electric vehicle (EV) batteries may be as much as 40 percent greater than previously assumed, a new study has found. Stanford University scientists uncovered this possibility by

Consumers' real-world stop-and-go driving of electric vehicles benefits batteries more than the steady use simulated in almost all laboratory tests of new battery designs, Stanford-SLAC study finds.
