Among the never-ending flood of “Don’t get me wrong—I love electric vehicles, but...” articles and posts, we read dire warnings that EV batteries will wear out in a few years, making the cars worthless, and that they can’t be recycled.
Oddly enough, the citizen journalists who write these pieces never seem to cite any sources for their helpful information about battery life. What do the people who work for automakers who’ve actually been selling EVs have to say about the issue?
Well, as
Nissan’s UK Marketing Director Nic Thomas recently told Forbes, “Almost all of the [EV] batteries we’ve ever made are still in cars, and we’ve been selling electric cars for 12 years.”
The much-predicted glut of obsolete EV batteries has not materialized, despite the fervent hopes of the anti-EV crowd. As Carlton Reid explains in a recent Forbes article, unlike phones or laptops,
EVs have sophisticated battery management systems (BMS) that are designed to maximize battery life. In the US, automotive battery packs are warranted against failure for 8 years or 100,000 miles by federal law, and industry experts expect most battery packs to last much longer than that. (Battery failure and battery degradation are two different things—all batteries lose capacity over time, and some drivers may find the gradual reduction in range unsatisfactory.)
“We haven’t got a great big stock of batteries that we can convert into something else,” said Thomas. “It’s the complete opposite of what people feared when we first launched EVs—that the batteries would only last a short time.”
Many EV batteries may outlast their vehicles, then enjoy a second life in a stationary storage application before finally being recycled. “At the end of the vehicle’s life—15 or 20 years down the road—you take the battery out of the car, and it’s still healthy, with perhaps 60 or 70% of usable charge.”
