A current examine from Canadian telematics firm Geotab has instructed that the “overwhelming majority” of EV batteries will probably outlast the life of electrical vehicles. The agency’s findings stand in distinction to the persistent anti-EV argument that electrical automobile batteries will solely final a couple of years earlier than they should be discarded.
The agency printed its estimates as an replace to a 2019 evaluation about EV battery degradation. Curiously sufficient, Geotab’s 2019 examine indicated that EV batteries have been degrading at a mean of two.3% per yr, as famous in a report from The Pushed. The agency’s current weblog put up, which included up to date information and evaluation from fleet utilization, instructed that electrical automobile batteries have seen a notable enchancment over time, degrading just one.8% per yr on common.
Contemplating that electrical automobile batteries at the moment are degrading just one.8% per yr on common, Geotab estimated that EV batteries might nonetheless have over 80% of their well being after 12 years. Total, the telematics firm estimated that EV batteries might final 20 years or extra at their present common degradation charge.
“Based on our information, the straightforward reply is that the overwhelming majority of batteries will outlast the usable lifetime of the automobile and can by no means have to be changed. If a mean EV battery degrades at 1.8% per yr, it’s going to nonetheless have over 80% state of well being after 12 years, typically past the same old lifetime of a fleet automobile,” Geotab wrote.
After all, as soon as electrical automobile batteries want substitute, the batteries themselves usually are not simply dumped right into a landfill. Batteries are comprised of worthwhile supplies, so firms equivalent to Redwood Supplies have made it their mission to grasp battery recycling. As estimated by Redwood, there’ll finally be a time when the battery business might have a closed-loop system, the place end-of-life batteries are recycled to create new ones.
Geotab’s EV battery degradation examine included quite a few different fascinating insights, equivalent to the truth that high-use electrical automobiles don’t actually exhibit considerably larger battery degradation than others. The agency, nonetheless, did observe that there’s an “observable distinction in battery well being between vehicles that routinely cost on Degree 2 in contrast to those who used Degree 1.”
