<p><P>PROBLEM TO BE SOLVED: To provide a power supply device for a vehicle capable of managing control of production of power and power consumption in an excellent state, while holding voltage of a power supply line within a prescribed reference voltage range. <P>SOLUTION: This device is provided with a battery 103 for supplying power to electric load 111a1 to 111e3 through the power supply line 108, a generator 102 for supplying power to the battery 103 and the electric load 111a1 to 111e3 through the power supply line 108, and a control device 105 for controlling generated power of the generator 102 and power consumption of the electric load 111a1 to 111e3. A charging/discharging power range of the battery 103 corresponding to a voltage command value range of the power supply line 108 is predicted from the range. The generated power of the generator 102 or the power consumption of the electric load 111a1 to 111e3 is adjusted so that actual charging/discharging power may be in the range. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
