Abstract
A load value of an external load is detected by a load value detector. When a heat quantity recovered by a heat load from a heat engine or a fuel cell is smaller than a predetermined value, a CPU calculates electric power to be consumed by an electric heater based on a relation between a heat value of heat load relative to a load value of a generator or fuel cell and a heat quantity recovered from generator or fuel cell stored in a memory of a power setting unit, so that the sum of heat quantities recovered from waste heat of heat engine or fuel cell and from generated heat of electric heater by heat load is the predetermined value, thereby controlling electric heater according to the result.
