P lug-in Charging Safety (2012 Model - Continued)
•
The AC cables are connected to the charger assembly. The high voltage
DC power cables from the charger assembly
battery assembly and are controlled by 12 Volt normally open charge relays
, HV system main relays
charging is not being performed, or the remote air conditioning system is
not operating, the charge relays
flow from the HV battery assembly to the charger assembly, and the relays
in the CCID (Charging Circuit Interrupter Device)
household power to the vehicle.
•
Both the high voltage power cables
from the metal body. High voltage electricity flows through these cables
and not through the metal vehicle body. The metal vehicle body is safe to
touch because it is insulated from the high voltage components.
•
Ground fault monitors and
leakage to the metal chassis while the vehicle is charging. If a malfunction
is detected, the CCID will illuminate its error light
•
The CCID contains a power light, an error light
reset button. When the charge cable assembly is connected to a 120 Volt
outlet, the power light illuminates. The TEST and RESET buttons function
like a conventional residential GFCI (Ground Fault Circuit Interrupter).
Pushing the TEST button opens the CCID relays, and pushing the RESET
button resets the circuit.
