US scientists at Stanford University have discovered that the batteries of electric vehicles could last up to 40 per cent longer than previously assumed. The

“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.
