Charge/discharge control device, charge/discharge control system, and remaining battery capacity adjustment method

Abstract

A charge and discharge control device () controls the charging and discharging of a plurality of capacitors () configure to be removably connected in parallel to a vehicle (). A receiver () acquires the remaining capacity of each of the capacitors (). A required power calculator () calculates the amount of power required to reach a station () where the exchange of battery packs () including the capacitors () is performed, from position information about the station () and the current location of the vehicle (). A target remaining capacity generator () calculates the target remaining capacity of each of the storage units () upon arrival at the station () from the required power amount calculated by the required power calculator () and sum of the remaining capacity of each of the storage units () acquired by the remaining capacity receiver (). A charge and discharge controller () performs charging and discharging among the storage units () so that the target remaining capacity calculated by the target remaining capacity generator () will be attained.
