tion is equipped to the plug.
While charging, if heat is gener-
ated due to looseness on the
outlet side etc., this function
suppresses heat by controlling
the charging current.
■Conditions for supplying
current to the vehicle
The CCID (Charging Circuit
Interrupting Device) is designed
to prevent electrical current from
being supplied to the charging
connector when it is not con-
nected to the vehicle, even if the plug is inserted into the outlet.
■Indicator operation
3 indicators are used to indicate
the following conditions.
Power indicator
Illuminates when electricity is flow-
ing to the CCID (C harging Circuit
Interrupting Device).
Charging indicator
Illuminates when charging is in
progress.
Error warning indicator
Flashes when there is an electrical
leakage or when a malfunction
occurs in the CCI D (Charging Cir-
cuit Interrupting Device).
■When a malfunction occurs during charging
The indicators on the CCID (Charging Circuit Interrupting Devic e)
use a combination of different statuses (not illuminated, illum inated
or flashing) to inform the user of internal malfunctions.
When the error wa rning indicator is illuminated or flashing, te mporarily
remove the plug from the outlet and then reconnect it to check if the error
indicator turns off.
If the error warning indicator turns off, charging is now possi ble.
