Abstract

A control device controls charging / discharging of an electric power storage device for supplying electric power to a load device. The control device includes: a limit value setting unit setting a limit value of charging electric power for the electric power storage device based on the state of the electric power storage device; a target setting unit setting a target value of the charging electric power based on the state of the load device and the limit value; a correction unit correcting the limit value based on a difference between the target value and the actual electric power input to and output from the electric power storage device; and a command setting unit setting a command value of the charging electric power based on the state of the load device and the corrected limit value.

Description

Technical field [0001] The present invention relates to a control device for a power storage device and a vehicle equipped with the control device for the power storage device, and more specifically to charge and discharge control of the power storage device. Background technique [0002] In recent years, as a vehicle that takes environmental issues into consideration, a vehicle that is equipped with a power storage device (for example, a secondary battery, a capacitor, etc.) and runs using the driving force generated by the power stored in the power storage device has attracted attention. Such vehicles include, for example, electric vehicles, hybrid vehicles, and fuel cell vehicles. [0003] In such a vehicle, in order to prevent the power storage device from malfunctioning or degrading due to overcharging or overdischarging of the installed power storage device, it is necessary to appropriately control the charging power and the discharged power of the power storage device. [000...
