One of the crucial continuously requested questions on electrical automobiles is, “How lengthy do the battery final?” That’s not a query about vary, both — however concerning the anticipated lifespan of the automobiles.

Whereas it might look like we don’t have a whole lot of historical past to again up any solutions we’d give, the reality is that modern electric vehicle batteries have been around since 1998, when the first Toyota Prius was launched. Within the almost twenty-five years since, we’ve seen several hybrids and EVs deliver hundreds of thousands of miles of service.

For EV house owners who put their automobiles by way of extra common responsibility cycles, battery degradation is pretty minimal. Some automobiles (particularly the Chevy Bolt EV) present 0% loss after a full yr of driving, and just about 8% after 100,000 of driving.

I feel battery life will most likely observe the lifetime of the car life. Personally, I feel it’s much less doubtless that individuals will place a brand new battery in an previous automotive.”
Why ought to Strubel care? As a result of monitoring end-of-life of EV batteries is vital to his new firm, Redwood Supplies, which is targeted on creating a brand new course of to recycle electrical automotive batteries.
The corporate is at present recycling 8-10GWh yr which it says is, “sufficient for a whole lot of hundreds of automobiles,” and, the supplies maintain getting higher the extra occasions they’re recycled. (!)
You’ll find out extra about Straubel’s new plans to recycle electrical automotive batteries on this interview, under, then scroll on all the way down to the feedback part and tell us what you consider Redwood’s potential influence on sluggish adopters’ views on EVs. Get pleasure from!
