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

Basic Control/Function 

The 12 volt battery sensor measures 12 volt battery 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 sensor to the gauge control module.
