<P>PROBLEM TO BE SOLVED: To provide a vehicle power supply apparatus which properly compensates a current sensor sensing a charging and discharging current from a storage device while suppressing an increase in the number of components and costs. <P>SOLUTION: The vehicle power supply apparatus includes a battery B that is charged from the outside of a vehicle, a current sensor 11 disposed on a charging and discharging passage for the battery B, temperature sensors 66 and 82 disposed on a temperature observation subject different from the current sensor 11, and a control unit 30 which controls the charging and discharging of the battery B based on output from the current sensor 11. The control unit 30 estimates the temperature of the current sensor 11 based on output from the temperature sensors 66 and 82, and compensates output from the current sensor 11 based on the estimated temperature. <P>COPYRIGHT: (C)2010,JPO&INPIT |
