Porsche Ventures invests in battery startup South 8 to boost cold-weather EV performance
All cars suffer when the mercury drops, but electric vehicles suffer more than most as heaters draw more power and batteries charge more slowly as the liquid electrolyte inside thickens. Drivers in Chicago found this out the hard way last January after many Teslas failed to charge during a deep freeze.
One startup, South 8 Technologies, says it can make cold-weather charging more reliable by filling batteries with a pressurized, liquified gas electrolyte instead of a liquid one. In the process, it hopes to slash the cost of lithium-ion batteries by 30%.
The company recently attracted new funding from Porsche Ventures in the form of a SAFE note, which will be applied to a Series B round that the company is starting to raise. Stepien said he could not disclose the size of Porsche Ventures’ investment.
