A Polestar and fast-charging battery pioneer StoreDot have successfully demonstrated the implementation of StoreDot’s Extreme Fast Charging (XFC) technology for the first time in an automobile.
In the test, a Polestar 5 prototype was used, which charged from 10 to 80% in just 10 minutes. The prototype recorded a consistent charge rate, starting at 310 kW and rising to a peak of over 370 kW at the end of charging.
This world-first demonstration used silicon cells – rather than individual cells in a laboratory environment. The 77 kWh battery pack – which has the potential to be increased to at least 100 kWh – could add 320 km of range to a medium-sized electric car in 10 minutes.
“Time is one of life’s greatest luxuries, and as a luxury electric car manufacturer, we must take the next step to solve one of the biggest obstacles to electric vehicle ownership – charging anxiety. With this new technology, on the road longer, when drivers stop, they will be able to get back on the road more quickly than ever before. In fact, this stopping time will be more similar to what is currently happening with a gasoline model,” said Thomas Ingenlath, CEO of Polestar.
It should be noted that the Swedish tram brand’s test proves that XFC technology works with the current DC charging infrastructure, which continues to feature more high-power DC chargers of 350 kW or higher.
