HYBRID INFORMATION
Temperature monitoring of the
charging cable
For the car's hybrid battery to be charged safely
every time, the control unit for the charging cable
and the plug have built-in monitoring devices for
the temperature.
Temperature monitoring takes place in the con-
trol unit and the plug.
NOTE
Volvo recommends a charging cable in
accordance with IEC 62196 and IEC 61851
which supports temperature monitoring.
Monitoring in the control unit
Charging is switched off if the temperature of the
control unit is too high. This is to protect the
electronics. This may take place at a high outer
temperature, for example, and/or when strong
sunlight shines directly on the control unit.
Monitoring at the plug
If the temperature at the power source to which
the charging cable is connected is too high, the
charging current is reduced. If the temperature
exceeds a critical level, charging is stopped com-
pletely.

IMPORTANT
If the temperature monitoring has automati-
cally lowered the charging current repeatedly
and charging has been interrupted then the
cause of the overheating must be investiga-
ted and rectified.
