Charging cable temperature monitoring*
To help ensure the vehicle's hybrid battery is reliably charged each time1 it is connected, the charging cable's control module and plug have integrated temperature monitoring devices.
The temperature in both the control module and the plug is monitored.
Temperature monitoring in the control module
To help protect the vehicle's electronics, charging is stopped if the temperature in the control module becomes too high. This may occur due to e.g. high ambient temperatures or strong sunlight directly on the control module.
Monitoring in the plug
The charging current is reduced if the temperature in the plug becomes too high. If the temperature exceeds a critical limit, charging is stopped completely.
Warning
Monitoring of the charging cable's temperature helps protect the vehicle's charging system but cannot ensure that overheating will never occur.
Important
Avoid exposing the control unit and its plug to direct sunlight. This could cause the overheating protection in the plug to reduce or cancel charging of the vehicle.
Important
If charging is often inadvertently interrupted, the charging cable and the vehicle's charging system should be checked by a trained and qualified Volvo service technician. The wall outlet should also be checked by a licensed electrician.
