BRUSA Elektronik AG, a Swiss maker of power electronics and motors for EVs, has announced a new on-board charging system that operates on three-phase current of up to 22 kW. BRUSA says its NLG6 system will be able to charge a typical EV in only an hour, with no need for an external DC charger.

“It was a big challenge to increase the power of our chargers by six times and not overly exceed the dimensions of standard chargers. We believe that through the immense reduction of the charging time, the acceptance of emobility will noticeably change,” says Philipp Matt, BRUSA’s head of engineering.

BRUSA says that vehicles from a “major European automaker” equipped with the NLG6 will go on sale by the end of 2012.

According to the company, on-board chargers in Europe normally operate with a maximum power of 3.7 kW, resulting in charging times of 6-8 hours. BRUSA says that “the fast charger itself requires no cost-intensive off-board infrastructure but can generally be used at all three-phase power supplies. Modern house connections and most public charging points are already equipped with the required power supply of 400 volts and 32 amperes.”

Other features of the NLG6 include PLC technology, which allows it to communicate through the charging cable, enabling internet connectivity and intelligent charging, as well as idle and peak power regulation and bidirectional operation.
