With the NLG664 BRUSA has set an milestone in e-mobility. The on board fast charger NLG664 is now available with 45-65 Hz input frequency and enhanced single phase current capability of 30 A. This provides a great flexibility for the worldwide use of our NLG664 on-board-charger.  Thanks to its performance upgrade the charger NLG664 can also be operated in countries with 60Hz mains frequency. The NLG664 is the world's first charger that allows the charging of a typical EV-battery in less than one hour from standard 3-phase AC grid and gives the additional option to charge with up to 7 kW from an appropriate single phase AC outlet.

The NLG664 is at the B-sample stage.


  • Full separation of mains and HV battery through galvanic isolation
  • In case of EMC requirements, compliance is given in combination with the vehicle
  • No DC - fault current, therefore the use of a Class A ground fault interrupter is possible
  • 2 x CAN interface: Vehicle CAN and Diagnostic CAN
  • Battery-friendly high power charging due to low battery ripple current
  • Enhanced temperature handling and maximum performance through patented Liquid PinĀ© cooling-technology and integrated power factor correction
The NLG664 generates virtually no Total Harmonic Distortion (THD), it even filters out network problems. The illustrated DSO measurement shows how low they are. For this reason, the simultaneous charging of several NLG664 on a grid connection is possible. With this charger, an electric vehicle is ready for the future and can be used without risk in large numbers.
