12 Volt Battery Management System Description
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.
After the vehicle is turned to the OFF (LOCK) 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 a message is displayed on the gauge control
module. As a result, the 12 volt battery sensor can alert the driver of an over a discharge in the ACCESSORY mode or automatically
turn off interior lights through the MICU.
