Polestar, in cooperation with StoreDot, is going to introduce ultra-fast charging (XFC) technology into production. This technology has been named “100 in 5”, and should allow charging the battery for 100 miles (160 km) in five minutes, can be integrated into existing battery pack formats, and does not require revolutionary changes in the design of the battery packs.
The companies demonstrated a prototype XFC charger for batteries in cases, as well as a prototype Polestar battery module integrating XFC technology at Polestar Day in Los Angeles. The company plans to demonstrate StoreDot’s XFC technology at full scale on the Polestar 5 prototype in 2024.
StoreDot’s approach seems to be to sacrifice energy density for much faster charging, including by managing the battery’s temperature during charging. The company uses silicon anodes and makes the components in its cases thinner than in more common items, which also helps dissipate heat during charging, reports ArsTechnica.
