New Polestar Battery Can Charge in 10 Minutes

New battery cells deliver ultra-quick charging

  • New cells allow fast charging from 0-100

  • Polestar sees production in 2-3 years

 


Polestar claims that a prototype of the Polestar 5 has made “charging history.” The EV went from 10 to 80 percent in exactly 10 minutes, bringing EVs down to nearly gas-vehicle fill-up times.

“What we did this month is, I believe, a world first,” said Polestar Battery System Chief Engineer Jens Groot. “For a standard vehicle without any novel cooling systems, we are looking at charging speeds I haven’t seen anywhere else. We reached consistent speeds of 310-380 kW.”

Getting individual cells above 300 kW is nothing new, Groot said. What the Polestar team accomplished for the first time was getting an entire pack in a real car to hit those rates. While it was a prototype, the cells came from supplier StoreDot and its silicon-dominant technology. It uses a silicon anode instead of the traditional graphite. The car had the same battery cooling pump and fan as the production car. Also impressive, Polestar said that charging speeds didn’t slow as they normally do during fast charging.

While adding 500 km of range in 10 minutes is a feat, that’s not all Groot was happy about. He said that the battery could take its full charge speed all the way to 100 percent. Every other EV battery falls off a charging cliff at 80 percent. 80-100 can take as long as 0-80.

“With this battery, it almost doesn’t matter when you stop to charge your car. Whether you stop to recharge at 10 percent or 60 percent, you’ll achieve the same speeds. In this sense, the experience is more like filling up your car at the petrol station. Because of that, this test really feels like a major step towards alleviating both range and charging concerns in customers. It definitely has the potential to be transformative,” said Groot.

It’s not a long-distance dream, either. Groot said we could see it in production in two to three years.
