| description | The present invention relates to the technical field of electrochemical battery energy storage system applications, and particularly relates to a battery energy storage BMS system enabling dual path-based information sampling and detection and protection control. Each battery module unit cell detection and sampling module of a battery string monitoring management module in a battery string direct current bus and string balancing management control device acquires electrical parameters, such as voltage, current, and electric quantity, and a temperature parameter of each battery string and all battery cells in real-time, and compares the same against pre-configured operation assurance parameters of an energy storage system so as to perform string-level electrical energy balancing. Upon detecting that a parameter of a unit battery has reached a preset hazardous state parameter range, a corresponding battery module unit cell detection and sampling module directly drives a corresponding battery string direct current power line connection/disconnection and protection circuit to disconnect a power path connecting a corresponding battery string to a battery string direct current busbar. The present invention saves investment costs while significantly improving controllability and safety of the energy storage system. |
