Battery Energy Control Module (BECM) Repair Service

For Volvo Hybrid & Electric models with 400V Li-Ion high-voltage battery systems

The Battery Energy Control Module (BECM) is located inside the 400V high-voltage Li-Ion battery pack and is responsible for complete battery management, safety control, and communication with the vehicle's propulsion and charging systems.

This listing is for a repair service focused on fixing no communication and control faults within the BECM.

Typical Fault Symptoms

  • - Vehicle will not start or go into READY mode
  • - High-voltage system disabled
  • - Charging not possible
  • - Hybrid / EV fault messages on dashboard
  • - Contactor control or safety isolation faults

Our repair service targets internal electronic failures causing loss of communication, safety shutdowns, and control faults.

Important Service Information

  • The vehicle will be immobilised while the BECM is removed.
  • The BECM is part of the 400V high-voltage system and is directly connected to:
    • - High-Voltage Battery Pack
    • - Onboard Charger (OBC)
    • - Inverter / Drive Modules
    • - Supplemental Restraint System (SRS)
  • All work requires high-voltage isolation, safety equipment, and controlled procedures.
