CHARGING CONTROL DEVICE

A charge control device (15) calculates a learning command value of a charging parameter used in a learning phase that is an initial period of a charge control period, operates a charger (14) in the learning phase to control the charging parameter to the learning command value, calculates a learning temperature rise rate that is a temperature rise rate of the secondary battery in the learning phase, based on the temperature of the secondary battery, calculates a charging-time temperature rise rate that is a temperature rise rate of the secondary battery in a charging phase that follows the learning phase, prior to the start of the charging phase, based on a limit temperature of the secondary battery and a duration of the charging phase, calculates a charging command value of a charging parameter which is used during a period from the start to the end of the charging phase, based on the learning command value, the learning temperature rise rate, and the charging-time temperature rise rate, and operates the charger in the charging phase to control the charging parameter to the charging command value.
