US 2025/0219218 A1 · ENERGY STORAGE DEVICE AND CHARGING/DISCHARGING CONTROL SYSTEM THEREFOR

Abstract

The present disclosure describes an energy storage device and its associated charging/discharging control system. This energy storage device comprises an energy storage power supply and a detachably connected battery pack. The energy storage power supply features a housing with a mounting part that includes an interface, a built-in battery, and an inverter, all arranged to avoid interference with the mounting part. User-accessible input and output interfaces are also present on the housing. The battery pack connects freely to the mounting part and includes a power output port designed for mechanical and electrical connection to the interface. The battery pack has two operational states: in the first state, it charges using power from the energy storage supply via the connection; in the second state, it couples with the inverter to output alternating current through the output interface.
