The charging cable is mounted on the vehicle as an accessory of the vehicle. Connecting
the cable between the vehicle and the home socket can make the main battery charged. There is the
switch in the regular charging plug of the charging cable. The switch is turned ON/OFF, depending
on the regular charging plug release button status. When the regular charging plug is correctly
connected with the vehicle, the switch should be ON and the signal should be input into the
EV-ECU. When the regular charging plug release button is pressed from that status, the switch
should be turned OFF and the signal should be input into the EV-ECU. This allows the EV-ECU
to detect the insertion status of the regular charging plug.

The charging cable has the charging circuit interrupting device. When connecting the charging
cable with home sockets, the AC power supply should be input into the charging circuit interrupting
device. At that time, the READY indicator (green lamp) of the charging circuit interrupting
device should be lit. When connecting the charging cable with home sockets and the vehicle,
the charging circuit interrupting device should send the pilot signal to the on board charger.
This allows the on board charger to detect the supplied currents and charging should be enabled.
When the main battery starts to be charged, the CHARGE indicator (orange lamp) of the charging circuit
interrupting device should be lit. When the main battery is finished to be charged, the CHARGE
indicator (orange lamp) should be extinguished. The charging circuit interrupting device has
the function detecting whether earth leakages exist or not;
also the charging circuit interrupting
device has the function detecting charging cable abnormalities. If detecting abnormalities,
the charging circuit interrupting device should shut down the AC power supply and should light
or blink the FAULT indicator (red lamp) of the charging circuit interrupting device.
