Siemens e-car charger cuts charging time in half

Siemens is launching a charging point on the European market that can charge electric cars with a normal battery capacity within an hour. The charging power has been doubled to 22 kW in the new CP700A series, which cuts the charging time in half.

“When developing the new charging point, we set ourselves three objectives: Charging must be fast, easy to do and safe,” said Ralph Griewing, head of the electrical mobility team of Siemens Energy. “And these objectives were achieved in full.”

The Siemens Charge CP700A charging point can be used to charge electric cars of different power ratings. In the fastest operating mode, the vehicle is supplied with a three-phase AC voltage at a current of 32 A, and is therefore charged at a power level of 22 kW. Charging is, however, also possible at 20 A in the three-phase mode. The charging point communicates with the vehicle over the charging cable to determine whether the electric car supports charging at maximum current or only at a reduced current level.
