High and Low Voltage Batteries
The high voltage battery, also known as the
drive motor battery, is a system of many
components that operate together to provide
the energy required for vehicle propulsion.
High voltage contactors, internal to the battery
pack, turn on and off to control the output of the
high voltage battery.
High Voltage Battery
The Chevrolet Volt's low voltage system (12V) utilizes
an AGM lead acid battery. The battery is located in the
rear compartment underneath the load floor. The low
voltage energy is utilized by vehicle modules to control
the high voltage battery contactors. Severing the low
voltage cables should cause the system to open the
contactors. The low voltage (12V) cable cut location is
found behind the left rear closeout panel in the rear
compartment of the vehicle.
