BATTERY CLUSTER TOPOLOGY AND CONTROL METHOD OF BATTERY CLUSTER FOR LITHIUM-ION BATTERY ENERGY STORAGE SYSTEM

The present invention provides a battery cluster topology for a lithium-ion battery energy storage system and a control method of battery cluster therefor. The battery cluster parallel topology for the lithium-ion battery energy storage system includes at least two parallel battery cluster units, and the battery cluster unit is composed of N battery packs (N is a natural number greater than or equal to 2), N bidirectional DC/DC voltage conversion modules, N bypass switches, BDCM coordination controller units, circuit switches, and primary buses for connection.
