12 Volt Battery Sensor

The 12 volt battery sensor is located between the 12 volt battery negative pole and the 12 volt battery ground cable.

Battery Management System - General Information

12 VOLT BATTERY MANAGEMENT SYSTEM DESCRIPTION - CONTROL/FUNCTION

The 12 volt battery sensor measures voltage, sensor temperature, and charge/discharge currents. According to these readings, 12 volt battery fluid temperature, internal resistance and state of charge are sent as signals from the 12 volt battery to the gauge control module.

Battery Management System - General Information

After turning the vehicle to the OFF mode, the 12 volt battery sensor observes the charge state of the 12 volt battery. When a designated threshold is reached, a signal is sent through the LIN circuit interface and displayed on the gauge control module. As a result, the sensor can alert the driver of over discharge condition when in the ACCESSORY position or automatically switch off room lamps through the MICU.

12 VOLT BATTERY MANAGEMENT SYSTEM DESCRIPTION - OVERVIEW

The 12 volt battery management system consists of the 12 volt battery sensor, the gauge control module, and the MICU. The 12 volt battery sensor measures current, voltage, and temperature values of the 12 volt battery. This data is used to control the interior lights.
