Tesla co-founder says electric vehicle batteries can last 15 years

Electric vehicle batteries can last up to 15 years, according to Tesla co-founder JB Straubel.

The best battery warranty currently offered by an electric vehicle manufacturer in the world is 10 years.

Electric vehicle batteries are expected to last up to 15 years, says JB Straubel, one of Tesla’s five co-founders and the electric vehicle maker’s longtime chief technology officer.

Straubell, who is an electric vehicle battery expert and was responsible for Tesla’s battery development program until 2019, said an electric vehicle can easily be used for 15 years in most cases.

I think people will probably keep the batteries in their cars for a long time and really get as much use out of them as possible. I also think the battery life will probably follow the life of the vehicle.

Straubell was the key person behind the battery cell design, supply chain and Tesla’s first concept from the Giga factory to the Model 3 production ramp.

Your comment is interesting with regard to the lifespan of electric vehicle batteries, because the best battery warranty currently offered by an electric vehicle manufacturer in the world is 10 years, for the Niro EV, the EV6 and the Soul EV from Kia.

In most cases, electric car manufacturers offer up to eight years of warranty on their batteries. Even Tesla offers an eight-year warranty on the batteries of its Model S and Model X cars.

Given this, Straubell’s comment indicates that EV batteries should last 50% longer than the best battery warranty currently available on the market.

It also indicates that an electric vehicle can easily be on the roads longer than a petrol or diesel vehicle, since most owners of internal combustion engine vehicles switch vehicles after about 10 years.

As Straubel’s comment indicates the useful life of current battery technology, research is ongoing to improve the technology. With this, the battery life could be even longer.
