  • a battery;

    a motor driven based upon electric power supplied from the battery;

    a discharge load that is a load other than the motor and that consumes electric power from the battery;

    battery capacity determining means for determining a remaining capacity of the battery; and

    control means for performing a discharge control of the battery for supplying electric power to the motor and the discharge load;

    wherein the control means allows the discharge of the battery until the remaining capacity becomes a threshold value higher than zero in a normal mode, andwhen the control means receives an instruction of checking a deterioration state of the battery from an external checking device, the control means changes from a normal mode to a service mode in which the control means allows the discharge of the battery until the remaining capacity becomes zero, and then, fully charges the battery so as to determine a chargeable capacity.
