Porsche's highly anticipated Taycan was supposed to be the first model capable of accepting 350 kW charging. During our conversations two years ago with Porsche about the then Mission E, the company noted it could reach 350 kW charging with off-the-shelf batteries. The vehicle was released today with a maximum charge rate of 270 kW, falling short of its target. Porsche told Lux this was due to limitations in battery performance, and infrastructure will remain rated to 350 kW charging if future vehicles can achieve the mark. Clients should view this as a strong indication of the limitation of battery fast-charging, as a $150,000 vehicle with experienced automotive engineers couldn't overcome limitations in battery chemistry.
