Direct Current To Direct Current Converter (G2391071): Operation: Notes

WARNING: This page is about a different variant/trim than selected.

The DC/DC converts the MHEV battery DC voltage of approximately 48V DC to 12V DC.

The DC/DC supplies all the vehicle 12V systems and charges the startup battery. The DC/DC communicates with the BCM /GWM . The DC/DC communicates through the HS CAN power mode zero systems bus. The BCM /GWM sends charging load requests and the DC/DC produces the correct output voltage and current to match the vehicle electrical load requests.

The electrical systems are powered from the DC/DC in all modes except in Power Mode 0 (vehicle locked and armed). The DC/DC also charges the startup battery through the BJB.

The HS CAN power mode zero systems bus is also connected to the following:

The Battery Energy Control Module (BECM) in the MHEV battery.
The Powertrain Control Module (PCM).
The BCM /GWM .
