“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 conducted by researchers from Stanford University explored the lifespan of batteries in electric vehicles (EVs).  Overall, the researchers f

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 changing the way they evaluate the lifecycles of such batteries: Instead of conducting customary tests that involve a constant rate of discharge followed by recharge,

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.
