DISCHARGE CONTROL APPARATUS FOR ELECTRIC VEHICLE
First Claim
1. A discharge control apparatus in an electric vehicle comprising:
- 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.

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.

12. A discharge control apparatus for use in an electric vehicle comprising:
-
an electric motor; a discharge load that is a load other than the motor for consuming electric power; battery capacity determining means for determining a remaining capacity of a battery; and control means for performing a discharge control of a battery for supplying electric power to the motor and the discharge load; wherein the control means allows a discharge of the battery until the remaining capacity becomes a threshold value higher than zero in a normal mode, and an external checking device operatively connected to the control means for providing instructions of checking a deterioration state of the battery, wherein said control means is changed from a normal mode to a service mode in which the control menas 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. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
