The industrial companies involved in the research project FastCharge presented the latest advancements in the field of fast energy supply for electrically powered vehicles. The prototype of a charging station with a capacity of up to 450 kW was inaugurated in Jettingen-Scheppach, Bavaria. At this ultra-fast charging station, electrically powered research vehicles created as part of the project demonstrated charging times of less than three minutes for the first 100 km (62 mi) of range or 15 minutes for a full charge—10-80 % state of charge (SOC).
The new charging station can be used free of charge and is suitable for the Type 2 version of the Combined Charging System (CCS), as is commonly used in Europe.
FastCharge is being run by an industry consortium under the leadership of the BMW Group; its other members are Allego GmbH, Phoenix Contact E-Mobility GmbH, Dr. Ing. h. c. F. Porsche AG, and Siemens AG. FastCharge is investigating the technical requirements that need to be met in terms of both vehicles and infrastructure to be able to tap into high charging capacities like 450 kW.
The Siemens energy supply system being used in the project enables researchers to test the the fast-charging capacity demonstrated by vehicle batteries. It can reportedly handle higher voltages of up to 920 V—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 that 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 simultaneously. The system is reportedly suitable for a number of different applications, including fleet charging solutions and, as in this case, charging along highways.
