Take the undeniably common — based on gross sales figures — European EV, the Renault Zoë, for instance. It has a normal vary of 245 miles per full cost. By the point that automobile is three years previous it will have misplaced 4.9 miles of vary.

Keep in mind, automobiles within the survey which might be six years previous use previous battery expertise. Many common EVs from again then, just like the Nissan Leaf, used passively cooled packs which have been proven to be much less efficient than actively cooled ones at defending the operational lifespan of EV batteries.
