Abstract: A discharge control apparatus in an electric motorcycle includes a main battery; a motor driven based upon electric power supplied from the main battery and a lighting device that is a load other than the motor for consuming electric power. A BMU determines a remaining capacity of the main battery. A control member performs a discharge control of the main battery for supplying electric power to the motor and the lighting device. The BMU and the control member allow the discharge of the main battery until the remaining capacity becomes a threshold value higher than zero. When the control member receives an instruction of checking a deterioration state of the main battery from an external checking device, the control member performs a discharge of the main battery until the remaining capacity reaches zero, and then, allows the main battery to be fully charged so as to determine a chargeable capacity.
