Traction Battery Wiring and Circuit Protection
Traction Battery Circuit Protection
•
The traction battery uses low and high voltage wiring.
•
The high voltage circuit is protected by a 400-volt 250 amp fuse
installed between batteries 20 and 21.
•
If the fuse opens or is removed, the high voltage circuit is
interrupted.
•
Two high voltage connectors connect the traction battery to the
vehicle systems.
•
The primary power (2-pin) connector is located at the rear of the
battery tray and transfers power to the motor/transaxle.
•
The auxiliary power (4-pin) connector is located near the front of
the battery tray on the passenger side. It transfers high voltage
power to the vehicle's auxiliary high voltage circuits.
•
Both high voltage circuits are part of the vehicle high voltage
interlock circuit (covered later in this lesson).
•
The low voltage connector is located near the front of the battery
tray on the driver side and transfers low voltage to the vehicle's
low voltage circuits.
– The low voltage connector is a 76-pin connector.
