BATTERY MANAGEMENT SYSTEM, PROCESSING DEVICE, BATTERY MANAGEMENT METHOD, AND BATTERY MANAGEMENT AND CONTROL SYSTEM

The present application discloses a battery management system, a processing device, a battery management method, and a battery management and control system, and relates to the field of power batteries. The battery management system includes: an information transmission module configured to transmit, under a condition that it is determined that a connection relationship between unfailing cells of a target battery pack changes when a target failure cell in the target battery pack is isolated, original configuration information of the target battery pack to a processing device, so that the processing device generates adjusted configuration information according to the original configuration information; an information reception module configured to receive the adjusted configuration information transmitted by the processing device, wherein the adjusted configuration information includes an identification of the target failure cell; a management module configured to perform management operations on the unfailing cells of the target battery pack according to the adjusted configuration information. According to the technical solution provided by the embodiments of the present application, the management accuracy of the BMS to the target battery pack may be guaranteed.
