A consortium led by BMW, Porsche and Siemens has created the world’s first publicly accessible 450kw charging station in a Bavarian town.
At the prototype charging station, research vehicles can be charged in less than three minutes for the for the first 100 kilometres of range, or 15 minutes for a full charge. This comfortably beats the best times set by set by Tesla vehicles.
The new charging station can be used free of charge right away and is suitable for electric models of all brands with the Type 2 version of the internationally widespread Combined Charging System (CCS), as is commonly used in Europe, said BMW in a statement.
The Siemens energy supply system being used in the project enables researchers to test the limits of the fast-charging capacity demonstrated by vehicle batteries.
It can already handle higher voltages of up to 920 volts – the level anticipated in future electrically powered vehicles.
The announcement of the charging station, while still very much a prototype, demonstrates that incumbent OEMs are serious about meeting and beating Tesla’s lead in EV technology.
According to BMW, the time saved as a result of the increased charging capacities is demonstrated in the example of the BMW i3 research vehicle.
A single 10-80 % SOC charging operation now only takes 15 minutes for the high-voltage battery, which has a net capacity of 57 kWh.
A Porsche research vehicle with a net battery capacity of approx. 90 kWh achieved a charging capacity of more than 400 kW, thereby allowing charging times of less than three minutes for the first 100 km of range.
