Polestar & StoreDot Successfully Charge Polestar 5 Prototype From 10-80% in 10 Minutes

Polestar and StoreDot have successfully demonstrated the implementation of StoreDot’s Extreme Fast Charging (XFC) technology in a car for the first time, charging a Polestar 5 prototype from 10-80% in just 10 minutes. The fully driveable verification prototype saw a consistent charge rate starting at 310 kW and rising to a peak in excess of 370 kW at the end of charging.

Storedot's technlogy has previously been tested as individual cells in a laboratory environment.

The specially commissioned 77 kWh battery pack – which has the potential to be increased to at least 100 kWh, could add 200 miles (320 km) of range to a mid-sized electric car in 10 minutes.

This test by Polestar and StoreDot battery engineers was designed to demonstrate proof-of-concept for StoreDot's XFC battery technology that could be applied to future Polestar vehicles.

StoreDot’s XFC battery’s modules have a structural function which improves mechanical properties and cooling ability while maintaining or reducing weight levels, with high recyclability and serviceability also paramount in the design of the pack.

The demonstration is the continuation of Polestar’s commitment to developing the best driving experience for the future through innovative technology partnerships.

Thomas Ingenlath, Polestar CEO, says: “Time is one of life’s greatest luxuries, and as a manufacturer of luxury electric performance cars, we need to take the next step to address one of the biggest barriers to EV ownership – charging anxiety. With this new technology, on longer journeys when drivers do stop they’ll be able to spend less time charging and be back on the road faster than before. In fact, that stop time will be more akin to what they experience with a petrol car today.”

Dr. Doron Myersdorf, CEO of StoreDot, adds: "We are very excited to share this impressive achievement today and proud to be on this journey with Polestar. Polestar’s commitment acknowledges that extreme fast charging technology is necessary to make widespread electric car adoption a reality. This breakthrough revolutionises ownership by eradicating the barrier of range and charging anxiety once and for all as drivers will be able to travel long distances with the same freedom and convenience as traditional fossil fuel-powered vehicles."

Headquartered in Gothenburg, Sweden, Polestar's cars are available online in 27 markets globally across North America, Europe and Asia Pacific.
