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
control unit and the plug.
NOTE
Volvo recommends a charging cable in
accordance with IEC 62196 and IEC
61851 which supports temperature moni-
toring.
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
outside 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 completely.
IMPORTANT
If the temperature monitoring has auto-
matically lowered the charging current
repeatedly and charging has been interrup-
ted then the cause of the overheating must
be investigated and rectified.
