Prototype 450kW fast charger opens in Germany
A demonstration 450kW fast charger has been opened in Germany with prototype chargers in vehicles.

The industrial companies involved in the FastCharge project opened the prototype of a charging station with a capacity of up to 450 kW in Jettingen-Scheppach, Bavaria. This can provide 100km of range in three minutes or 15 minutes for a full charge (10-80 % State of Charge).

The €7.8m project is led BMW with Allego, Phoenix Contact E-Mobilit, Porsche and Siemens and is cooridinated by NOW, the National Organisation Hydrogen and Fuel Cell Technology. The 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 Combined Charging System (CCS), providing three times the capacity of current fast chargers.

 

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 system integrates both the high-power electronics for the charging connections as well as the communication interface to the electric vehicles. This charge controller ensures the output is automatically adapted so that different electric cars can be charged using a single infrastructure.

The system’s flexible, modular architecture permits several vehicles to be charged at the same time and can be used for fleet charging solutions as well as charging along highways. In order to link the system to the public power grid in Jettingen-Scheppach as part of the project, a charging container was set up with two charging connections: one with 450 kW and a second with 175 kW.

The Allego charging station prototypes now presented use the European Type 2 version of the well-established Combined Charging System (CCS) charging connectors. This standard has already proved successful in numerous electrically powered vehicles and is widely used internationally. In order to meet the demands of fast charging at high capacity, cooled HPC
