OnBoard Charger

The optimized and adaptable charging system

Highlights

  • Ultra compact 22 kW / 32 A Onboard Charger
  • Compatible with all standard AC charging stations
  • Charging method for all common battery technologies
  • Very high efficiency (> 94%) thanks to the most modern SiC semiconductors
  • Optional: PowerLine communication

Our ultra compact OnBoard Charger OBC_22kW is compatible with all single or three-phase AC charging stations and Type 2 wall-boxes.
The optimized and adaptable charging process gently charges all common high-voltage batteries in various voltage classes up to 850VDC.
By using the latest silicon carbide semiconductors, we set the standards in terms of efficiency, volume and weight.
For very large batteries, the charging power can be scaled by connecting several OBC_22kW in parallel using different parallel modes.

  • Very efficient switching technology using Silicon Carbide (SiC)-technology (Effiiency >94%)
  • Input power factor > 99 %, very low THD
  • Integrated ComModule for automatic inlet detection and charging mode selection (CP, PP)
  • Water Cooling

Option: "embedded PowerLineCommunication" (ePLC) for DC charging via a CCS input The OBC automatically detects the connection with a DC fast charging station, handles the monitoring and security mechanisms on the CCS connector and organizes the safe "pairing" of the charging station with "his battery" in accordance with the current standards.


PowerLine Communication (PLC)

⦁ Extension module for controlling DC direct charging via CCS2 charging connector by the OBC ⦁ Communication with external DC charging station according to DIN SPEC 70121
