Charging the high voltage battery

Ground fault breaker in charging cable

Ground fault breaker in charging cable

The control unit for the charging cable charging cable has a built-in ground fault breaker that protects the car and the user from electric shocks caused by system faults.

Warning

Charging the high-voltage battery must only take place with grounded and approved 230 V sockets (alternating current). If the capacity for the socket or fuse circuit is unknown, ask a licensed electrician to check the capacity. Charging above the capacity of a fuse circuit may lead to fire or damage the fuse circuit.

Warning

  • The charging cable's overvoltage protection helps to protect the car's charging system, but cannot guarantee that overload will never occur.
  • Never use visibly worn or damaged electrical sockets. This could cause fire or serious injury.
  • Never connect the charging cable to a cable extension.
  • Maintenance or replacement of the high-voltage battery must only be performed by a trained and qualified Volvo service technician.
  • Do not use a charging cable that has not been recommended.
  • An external timer must not be used between the charging cable and the electrical socket.
  • One or more adapters must not be used between the charging cable and the power socket.

Important

The ground fault breaker does not protect the 230 V socket (alternating current)/electrical installation.

Important

  • Check the capacity of the socket.
  • Other electronic equipment connected to the same fuse circuit must be disconnected if the total load is exceeded.
  • Do not connect the charging cable if the socket is damaged.
