A controller for a lithium ion secondary battery, includes an electronic control unit configured to: detect an SOC of a lithium ion secondary battery that is a controlled object; set an upper limit SOC and lower limit SOC of a range of use of the lithium ion secondary battery on the basis of the SOC of the lithium ion secondary battery; record a charge history and discharge history of the lithium ion secondary battery; determine whether the lithium ion secondary battery is in an excessive charging state or an excessive discharging state on the basis of the charge history and the discharge history; and raise the lower limit SOC when the lithium ion secondary battery is in the excessive charging state or lower the upper limit SOC when the lithium ion secondary battery is in the excessive discharging state.
