Hybrid/EV Battery Pack Current Sensor

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

The Hybrid/EV Battery Pack current sensor is a three-wire hall effect sensor that measures current flow from the hybrid/EV battery. The battery energy control module applies 5 volt and provides a low reference to power the sensor. Current measurement is communicated to the battery energy control module via a signal circuit.

The Hybrid/EV Battery Pack current sensor is located in the generator battery disconnect relay assembly. The generator battery disconnect relay assembly is a plastic tray that is secured to the top of the Starter/Generator Control Module. The generator battery disconnect relay assembly also contains the high voltage contactors, pre-charge resistor, and a series of bus bars and cables that electrically connect the hybrid/EV battery to the Starter/Generator Control Module. The Hybrid/EV Battery Pack current sensor monitors current on the hybrid/EV battery negative bus bar.
