Calendar ageing dominates electric vehicle battery degradation when stationary

16th June 2021

Dr Alana Zülke from Altelium’s battery research team at Lancaster University is lead author of a new, widely published research paper. It features on the front page of the academic journal Batteries and Supercaps and Dr Zülke highlights a key finding:

“Calendar ageing dominates electric vehicle battery degradation when parked. In the UK, a car will spend on average more than 95% of its time parked. To improve the lifecycle of batteries, it is vital to define the optimal conditions to reduce such degradation.”

This has important implication for fleet managers and of course the warranties and insurance products around battery cells and electric vehicles. To read the implications of this on battery health and management issues please go to EV Fleet World:
