The secondary battery packs each have: secondary batteries; a charge switch means that turns a charging path to the secondary batteries ON and OFF; a discharge switch means that turns a discharging path from the secondary battery ON and OFF; and a current-limiting means that causes the secondary battery to discharge while limiting the current to, or below, a fixed value. When switching from the secondary battery pack connected to the input/output terminals of the system to a first secondary battery pack in which voltage is higher than in the second secondary battery pack, the host device causes the charge switch means of the second secondary battery pack to turn OFF the charging path while in a state in which the current limiting means of the first secondary battery pack will cause a discharge operation to begin while limiting the flow of current."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secondary battery pack connection control method for controlling connection of input and output terminals in power storage system comprising plurality of secondary battery packs","description":"A power storage system has a plurality of secondary battery packs and a host device.
