Key Hybrid Components (cont.)
The generator control module, which is mounted on the left side of
the engine, manages the routing of the 36 volt electrical system.
The generator control module receives the electrical current
through two central terminal blocks that contain the 3-phase, 12
volt battery and 36 volt generator battery cables. These cables
enter the blocks from the bottom and side. A protective plate
covers the terminal blocks and cables.
Two coolant hoses, attached to the back of the module, connect
the generator control module with the engine’s cooling system.
These hoses may contain hot coolant that could scald if they are
disconnected or cut.
Note that blue wiring is used to indicate intermediate voltage.
Cables from the starter generator, 12v
battery and 36v battery enter the side and
bottom of the generator control module
