Polestar 5 with 77-kwh battery charged from 10-80% in 10 minutes [Video]

EV startup Polestar recently demonstrated the rapid charge capability of a new lithium-ion battery being developed by Israeli company StoreDot.

For the demonstration, a Polestar 5 prototype fitted with a 77-kwh battery from StoreDot was able to charge from 10-80% in just 10 minutes using a DC fast charger.

According to Polestar, the prototype experienced a consistent charge rate starting at 310 kw and rising to a peak of more than 370 kw at the end of the charging session.

In a midsize sedan like the 5, Polestar said a 10-minute charge at such rates could add around 200 miles of range. The company also said the StoreDot battery could potentially be increased to at least 100 kwh of capacity in a vehicle like the 5.

StoreDot’s battery, known as an Extreme Fast Charging (XFC) battery, is claimed by the company to use silicon-dominant cells. The company also claimed the battery doesn’t require sophisticated cooling systems.
