<P>PROBLEM TO BE SOLVED: To maintain and manage electricity demand in a vehicle to be a proper state with a low cost and by a simple constitution in such a method that can be introduced to the vehicle easily. <P>SOLUTION: An electricity generation manager 17 controls the generation of the electricity of an alternator 11 or the charge of a battery 12 while monitoring the state of the battery 12 (SOC or the like) and further calculates unit fuel consumption per unit electricity generation as the cost of electricity (electricity generation cost) and transmits information about the cost of electricity and the state of the battery 12 to an electricity manager 14. The electricity manager 14 obtains the total electricity consumption of the load from the detection result of a current sensor 13a, produces the cost of the electricity corresponding to the current market cost on the basis of the total electricity consumption, received cost of the electricity and the received battery 12 state and transmits the cost of electricity to each load 21-24. Each load 21-24 sets oneself to electricity saving mode when the cost of the electricity is higher than the cost of purchased electricity by comparing the transmitted cost of the electricity with the cost of purchased electricity set to oneself. <P>COPYRIGHT: (C)2012,JPO&INPIT |
