DISCHARGE CONTROLLER

摘要

A remaining capacity calculation unit (110) calculates the remaining capacities of batteries (300-1, 300-2) connected in parallel to one another, and, if one of the batteries (300-1, 300-2) has a remaining capacity amount which, calculated by the remaining capacity calculation unit (110), becomes the same value as a first threshold value stored in a storage unit (120), a control unit (130) preferentially discharges that battery until the remaining capacity thereof becomes the same value as a second threshold value stored in the storage unit (120).
