Abstract
A method is disclosed that defines a protocol for distributing power to high voltage components when two conditions exist: they being when the vehicle is being propelled or operated and when the power requested of the power supply is less than what the power supply can provide. The method determines which high voltage components can receive reduced or intermittent voltage and still allow the vehicle to operate in a proper manner. Calibrations of the usage and energy loss are based on parameters that dictate how important it is that a particular high voltage component receives as much of its requested power as possible. The critical function components will be weighted differently than those less critical components.
