The Porsche Taycan and the future Audi e-tron GT can make use of 350 kW chargers to get to 80% charge in 15 minutes. 350 kW chargers are being deployed on the Ionity and Electrify charger networks now:
Volkswagen probably will be the biggest producer of battery electrics within 3 years. They own 12 car brands (including Porsche and Audi https://www.volkswagenag.com/en/brands-and-models.html). VW also has a stake in Ionity and they own Electrify America and Electrify Canada.
If this charging technique really does work then I imagine VW will license it.
Reading between the lines, the constraint is that today’s chargers are always monotonically increasing state of charge with a roughly steady DC applied current (tapering slightly at the high end). Adding in something like pulsed charging or even some reverse-voltage segments could potentially change the charging dynamics enough to let the battery charge much faster without damage.
Comments
Chargers already pay attention to charging curves and temperature. Is there really much room for safely charging existing batteries faster?
