<p><P>PROBLEM TO BE SOLVED: To correct the power consumption of equipment connected to a dc power supply to a proper one and increase the accuracy of the energy balance of a system including the dc power supply. <P>SOLUTION: When a running motor 26 is stopped, a DC/DC converter 30 is stopped, and an output voltage and an output current outputted from the dc power supply 20 are detected and the power consumption of an air conditioner 40, efficiencyηof an inverter 42, and a correction value K used when the power consumption is calculated are acquired from an air conditioner ECU46. Then, a deviation between the product of the output voltage by the output current and a value obtained by dividing the power consumption by the product of the efficiencyηby the correction value K is calculated. Based on the deviation, the correction value K is corrected, and the correction value K of the air conditioner ECU46 is updated with the corrected correction value K. As a result, the power consumption of the air conditioner 40 can be more appropriated, and the accuracy of the energy balance of an electric vehicle 10 can be increased. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
