The Polestar company is testing an extremely fast charging station for the traction battery on its electric car. With the help of the Israeli company StoreDot, the automaker charged the electric car from 10 to 80 percent in just 10 minutes.
The test involved a prototype Polestar 5 with a 77kWh battery, but the pack could be expanded to 100kWh, which would allow the electric car to get a range of 322km in just 10 minutes.
“Thanks to this new technology, during long journeys, drivers will be able to spend less time recharging and get back on the road faster than before”– said Thomas Ingenlath, CEO of Polestar.
According to himwith the new station, the stopping time for recharging will be more similar to what drivers experience today when refueling gasoline cars.
The batteries used in the Polestar 5 are known to be equipped with StoreDot XFC technology, which uses a silicon cell. Experimental batteries have excellent cooling properties, which means that cars do not need additional cooling equipment for fast charging to be safe.
This test marked the first time StoreDot Extreme Fast Charging (XFC) batteries were tested outside of the lab and in a real car. During the demo, the Polestar started charging at 310 kW, and by the time it reached 80 percent charge, the car was charging at 370 kW. This is an important factor in this test, as the recharging process slows down as the batteries of existing EVs become full.
