Electric cars can be charged in an hour at a maximum charging power of 22 kilowatts

Siemens’ charging point Charge CP700A can charge electric cars with a normal battery capacity within an hour. The charging power has been doubled to 22 kilowatts in the new series, which cuts the charging time in half.

Siemens has received a major order for its model Charge CP700A charging point from Portugal. As part of the Portuguese program to promote electromobility (MOBI.E), Siemens Portugal concluded a framework agreement for delivery of up to 300 charging points. A binding order for 100 of these charging points was placed immediately by the customer INTELLI, as the coordinator of the Portuguese program. INTELLI is planning the setup of the charging infrastructure network in Portugal and intends to install the charging points in 25 cities by 2012, at public parking lots and near shopping centers, hotels and airports.

"I am more than pleased that we received a major order for 100 Charge CP700A charging points so soon after taking up series production of the units. Rapid charging technology is a hot topic", said Ralph Griewing, head of the Siemens business segment Electric Vehicle Infrastructure. The Charge CP700A charging point, which was introduced onto the market in the spring, 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 amps, and is therefore charged at a power level of 22 kilowatts. The normal charging time has now been reduced to one hour with this new charging point series. The goal Siemens has set for itself over the medium term is to develop rapid charging systems with a charging time of less than 15 minutes.

The Charge CP700A charging point uses AC voltage and can be easily integrated into any standard European city grid. The column can also be incorporated into a smart grid and supports functions such as remote control of the charging power to forestall grid bottlenecks and to enable charging explicitly using power from renewable energy sources.
