Extreme Fast Charging
Polestar, together with StoreDot, is experimenting with a Polestar 5 that can be charged extremely quickly. A practical test proved promising.
The Polestar 5 won’t make its appearance until later this year at the earliest, but it is already being used as a test car for a technology that may come onto the market later. Polestar is joining forces with StoreDot, which is developing so-called ‘Extreme Fast Charging’, or XFC. This should reduce EV charging times even further. The Polestar 5 in the photos is equipped with a new battery that is not yet available, a battery with silicon anodes instead of the usual graphite anodes.
StoreDot has managed to prepare this battery for much higher charging capacities than is usually the case with EVs. For example, this Polestar measured a peak charging power of more than 370 kW towards the end (80 SOC) and a consistent charging power of 310 kW from the start of charging. Much less fluctuation in charging capacity than normal and, according to Polestar, this ensures that approximately 320 km of driving range can be recharged in 10 minutes. The battery of the Polestar 5 was charged from ten to 80 percent in ten minutes, while such a charging session takes just half an hour for most electric cars. Polestar says you should be able to go from a 50 to 80 percent full battery in about five minutes.
There are currently no concrete plans to make this technology available in the Polestar 5. Polestar does say that this may still be available in Polestars in the future.
