<P>PROBLEM TO BE SOLVED: To provide an electromotive vehicle having a charge/discharge controller for enhancing estimation accuracy on the SOC of an electricity storage mechanism. <P>SOLUTION: A first electricity storage part 10 is an assembled battery and divided into n battery blocks B11 to B1n (n is a natural number) each comprising series-connected several cells. An ECU 50 executes a reset action on the SOC of the storage part 10 when the ECU 50 is brought to a state allowing it to be charged by means of an external power source. The ECU 50 causes the storage part 10 to discharge at a constant current by controlling a corresponding converter while setting reset values on the respective battery blocks based on battery voltages Vb11 to Vb1n and battery temperatures Tb11 to Tb1n at a time point when any one of the battery voltages Vb11 to Vb1n is lower than a reset voltage. The ECU 50 resets the SOC of the battery blocks B11 to B1n in the storage part 10 at the reset values severally set. <P>COPYRIGHT: (C)2009,JPO&INPIT |
