Abstract
An electrical power supply device configured to interface with a start-stop controller within a vehicle includes a DC-DC power convertor receiving an input voltage and producing a first output voltage or a second output voltage that is less than the first output voltage and a device controller in communication with the DC-DC power convertor. The device controller has one or more processors and memory. The memory includes instructions which causes the device controller to command the DC-DC power convertor to output the first output voltage when the device controller receives a run signal from the start-stop controller or detects that the input voltage is above a voltage threshold or output the second output voltage when the device controller receives a stop signal from the start-stop controller or detects that the input voltage is below a voltage threshold. A method of operating the electrical power supply device is also presented.
