Abstract
A system using a computer to be configured to perform particular actions by virtue of having software, firmware, hardware, or a combination installed. One aspect includes a system, programmed to receive a fault signal from an auxiliary battery sensor. The system also determines if a low voltage set point is greater than the main battery voltage, and sends an open switch signal to a battery isolation switch if the low voltage set point is greater than the main battery voltage value. The system will send an auxiliary set point signal to an auxiliary battery charger to maintain a low voltage. The system will receive a current signal from an auxiliary battery sensor to indicate an auxiliary battery current value. The system also determines if the auxiliary battery current is above a maximum current value, and send a disable auxiliary battery maintenance signal to the auxiliary battery charger.
