Circuit/System Description

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

The Battery Energy Control Module uses a single battery current sensor to determine the current flow out of the Hybrid/EV Battery Pack. The Battery Energy Control Module applies 5 volts and provides a low reference to power the sensor. Current measurement is communicated to the Battery Energy Control Module via a signal circuit.
