With the NLG6 series, BRUSA has set another milestone in electromobility: It is the world’s first series-produced 22 kW charger in the vehicle. Thanks to its compact and lightweight design, it fits everywhere, even in small city cars.

While the galvanic isolation guarantees electrical safety, the clever electronics ensure high efficiency and quiet operation. The device can be operated on single-phase and three-phase sockets of different power and thus offers maximum flexibility. Precise control and correction of the power factor (PFC) ensure problem-free and reliable operation. By connecting NLG6 devices in parallel, an even higher charging capacity can be achieved. This may be necessary for heavy commercial vehicles, for example.


  • Complete galvanic separation between the mains and the HV battery
  • High IP protection class
  • Evaluation of the external PT1000 sensors
  • Residual current circuit breaker type A is sufficient due to reinforced insulation
