CONTROL DEVICE FOR SECONDARY BATTERY AND OUTPUT CONTROL METHOD FOR SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a control device for a secondary battery capable of suppressing the lowering of the service life of the secondary battery while improving the reliability of engine start and an output control method for the secondary battery.

SOLUTION: This control device for the secondary battery 40 mounted on a vehicle having an internal combustion engine as a power source comprises a control part 5. When the index indicating the stored state of the secondary battery 40 reaches discharge stop conditions, the discharge stop of the secondary battery 40 is notified to the vehicle ECU 20 by the control part 5. When the power supply to the starter motor of the internal combustion engine by the secondary battery 40 is predicted, the discharge stop conditions are relaxed by the control part 5.
