PROBLEM TO BE SOLVED: To provide a discharge control method of a secondary battery that allows an occupant to select a discharge lower limit voltage so as to enable long-distance travelling, while maintaining cycle characteristics of the battery.SOLUTION: By providing two different discharge lower limit voltages Va, Vb of a secondary battery used as a vehicle power supply, and allowing an occupant to select a change of the discharge lower limit voltage from the voltage Va to the voltage Vb, a discharge control method of a secondary battery that allows an occupant to select a discharge lower limit voltage so as to enable long-distance travelling, while maintaining cycle characteristics of the battery, can be provided. |
