Abstract
A charge controller for a vehicle passive energy system employs an interface to a plurality of charge sources including intermittent sources, such as vehicle mounted solar photovoltaic (PV) panels and the vehicle engine and alternator, and an interface to a plurality of charge loads, such as a comfort heating ventilation, refrigeration and air conditioning (HVAC) system and auxiliary vehicle loads. Charge logic computes which of the plurality of sources will supply the charge current and which of the plurality of loads will receive the charge current, and a switch responsive to the charge logic will direct the charge current from at least one of the plurality of sources to at least one of the loads, the plurality of charge sources mutually exclusive from simultaneously powering a common load.
