Abstract
A battery cluster management device and a battery energy storage system are provided. The battery cluster management device includes a networking circuit and an integrated controller, a connecting circuit of the networking circuit and a power conversion circuit connected in series, the integrated controller is respectively connected to the connecting circuit, the power conversion circuit, and a BMU in a battery cluster, and the integrated controller is configured to: perform a preset battery management process according to preset electrical information fed back by the connecting circuit and the BMU, and control the power conversion circuit to perform a preset current conversion process. In the present disclosure, the connecting circuit and the power conversion circuit are integrated, thus repeated voltage and current detection circuits and corresponding soft start circuits are unnecessary, the integration level of the battery cluster management device is improved effectively, and the overall cost is reduced.
