An energy storage system is provided. The system includes an energy storage device including at least one battery module, a power adjuster that adjusts power of the energy storage device, a controller that controls the energy storage device and the power adjuster, a rack that accommodates the energy storage device, the power adjuster and the controller, the rack including at least one stationary coupler fixed to a movable unit and at least one support device that supports the energy storage system against the moveable unit.

Mobile energy storage system

An active balancing control apparatus and method with an active balancing algorithm to charge and discharge a plurality of batteries connected in series. The active balancing control apparatus may be designed to simultaneously charge and discharge a plurality of batteries, connected in series and having different charge/discharge characteristics, using an active balancing circuit. The apparatus may perform switching to achieve balancing of each of the batteries so that all the batteries may be charged at a maximum voltage.

Apparatus and method with active balancing circuit and active balancing algorithm for charging and discharging secondary batteries connected in series

An algorithm and a direct current (DC) microgrid charge/discharge system with the algorithm are provided that noticeably increases charge/discharge voltage during charging and discharging by connecting a plurality of secondary batteries in series, compared to a single battery, that increases power conversion efficiency of a DC-to-DC (DC/DC) converter for charge/discharge power control by setting an appropriate voltage of a DC microgrid to be about twice a maximum voltage of a battery group, that enables charging and discharging to be stably performed regardless of a change in the battery group by adding a linear constant current source, that increases power conversion efficiency of the DC microgrid charge/discharge system by configuring a DC energy storage system (ESS) used for both charging and discharging with a combination of a typical electrolytic condenser and a super condenser or a group of the secondary batteries, and that simplifies the DC microgrid charge/discharge system.

Direct current (DC) microgrid charge/discharge system for secondary batteries connected in series

A monitoring apparatus and method of a battery contact point that autonomously measures contact resistances of a contact terminal for directly connecting a battery for charging/discharging and a circuit in a charge/discharge apparatus for charging/discharging a single secondary battery or a plurality of secondary batteries in series.
