Abstract

A charging control device that executes charge control appropriately without reducing effects of charge control, and is configured to include a charged state calculation unit configured to calculate remaining capacity of battery that can be charged and discharged, based on signal from a sensor to detect state of the battery; an accumulated charge and discharge calculation unit configured to calculate an accumulated amount of charge and discharge of the battery after activation of the battery, based on the signal from the sensor; an execution determination unit configured, in a case where remaining capacity calculated by charged state calculation unit is less than first threshold, to determine whether to execute charge control to recover remaining capacity of the battery, based on accumulated amount calculated by accumulated charge and discharge calculation unit; and charge control unit configured to execute charge control following determination result by execution determination unit.
