Polestar and StoreDot Successfully Charge Polestar 5 Prototype From 10-80% in 10 Minutes - Seite 2

In today's commercial EV batteries, fast charging rates can vary greatly depending on the battery’s state of charge (SOC), sometimes dropping significantly as SOC increases. During this test, Polestar saw charging speed rise from 310 kW at 10% SOC to over 370 kW at 80% SOC, proving the technology’s steady charging rate with no significant change in charging speed or efficiency whenever a driver decides to stop within this wide state-of-charge range.

Importantly, the test proves XFC technology works with today’s DC charging infrastructure, which continues to feature more high-power DC chargers of 350 kW or higher.

This means drivers will be able to spend less time stopped to charge their vehicle, which for a 10-80% charge on many modern EVs could still take around 30 minutes. By reducing that time to 10 minutes, the charging time for a vehicle with XFC technology is much closer to what you would experience when filling a car with petrol. And thanks to the consistent charge speeds on offer, with a suitable charger, consumers could stop for five minutes at 50% SOC and continue their journey with over 80% SOC.

Dr. Doron Myersdorf, CEO of StoreDot, comments: "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."
