Abstract: A full current balancing method of SOC for an energy storage system is provided. DC output terminals of each battery pack are connected in parallel with a half-bridge control circuit to form a battery module, positive and negative electrodes of battery modules are successively connected in series to form a battery cluster. In operation, SOCs of the battery modules are sorted, battery modules with lower SOCs are put in operation first when charging, and the battery modules with higher SOCs are put in operation first when discharging, thereby achieving full current balancing of SOC among the battery packs in the battery cluster. After multiple battery clusters are connected in parallel to form a battery stack, current of the battery cluster with a low SOC is increased, and current of the battery cluster with a high SOC is decreased, thereby achieving balancing of SOC among the battery clusters.

Abstract: The invention discloses a full current control battery module and an energy storage system of full current control battery, belonging to the field of electric energy storage, wherein the full current control battery module comprises an energy transmission control unit, a relay energy unit and a current control unit. The invention can realize the separate current control of each battery module and isolate the influence of the current generated by the external DC system on the battery module.

Abstract: A power conversion method for an AC direct grid-connected type battery energy storage system is provided. The AC direct grid-connected type battery energy storage system includes at least one energy storage module, each energy storage module includes A, B and C three phase units composed of upper bridge arms and/or lower bridge arms, each bridge arm includes series-connected full-controlled battery modules and an inductor connected in series. High-voltage terminals of all the upper bridge arms of the energy storage module are connected to form a positive DC bus, and low-voltage terminals of all the lower bridge arms of the energy storage module are connected to form a negative DC bus. A low-voltage terminal of the upper bridge arm and a high-voltage terminal of the lower bridge arm of each phase unit are connected to form an AC terminal of the phase unit to connect with an external AC system.
