POWER DISTRIBUTION MANAGEMENT FOR A VEHICLE

A power management system for a vehicle includes a power source, switching circuitry, and a first converter electrically interposing the power source and the switching circuitry. The first converter has a first power output threshold. A second converter electrically interposes the power source and the switching circuitry. The second converter has a second power output threshold lower than the first power output threshold. Control circuitry is configured to, in response to a key-off state of the vehicle, control the switching circuitry to supply power to at least one load, compare the power drawn from the second converter by the at least one load to the second power output threshold, and communicate an output to limit the power drawn from the second converter by the at least one load in response to the comparison.
