Polestar to Test StoreDot’s Fast-Charging Battery, Could Add 100 Miles of Range in 5 Minutes

Polestar joins forces with StoreDot to integrate fast-charge batteries in its vehicles, aiming to revolutionize EV experience with significant reduction in charging times and potential mass production by 2027.

• Polestar, backed by Volvo and Geely, is collaborating to test the fast-charge batteries developed by StoreDot, potentially allowing for 100 miles of range to be added in just five minutes.
• StoreDot's fast-charging technology works by sacrificing energy density for much quicker charging, achieved partially by managing the battery's temperature while it charges, using silicon anodes, and making components thinner to assist with heat rejection during charging.
• Testing will occur over the next year using a StoreDot battery pack in a prototype Polestar 5 sedan, with hopes that cars using its extreme fast-charging batteries could hit the roads by 2027.
• For the batteries to charge at their fastest speed, charging stations would need to be upgraded to 350 kilowatts; current networks support speeds of up to 250kW.
• In 2022, Polestar invested in StoreDot, a start-up that initially focused on mobile phone chargers before shifting its attention to electric vehicles when Daimler became a strategic partner in 2017.
