An electrical power supply device is configured to communicate with a start-stop controller that automatically shuts down and restarts an internal combustion engine in a vehicle, and comprises a DC-DC power convertor, a device controller, and interface circuitry comprising a transceiver configured to communicate between the start-stop controller and the device controller. The device controller causes the DC-DC power convertor to produce a first voltage in response to a first signal from the start-stop controller indicating that an input voltage will remain equal to or greater than a threshold voltage, and to produce a second voltage in response to a second signal from the start-stop controller indicating that the input voltage may become less than the threshold voltage. The device controller further causes negotiation of a power delivery contract with a consumer device at a first output power in response to the transceiver receiving a first signal denoting that the start-stop controller has indicated that the input voltage will remain equal to or greater than the threshold voltage, and renegotiation of the power delivery contract with the consumer device at a second output power less than the first output power in response to the transceiver receiving a second signal denoting that the start-stop controller has indicated that the input voltage may become less than the threshold voltage.
