The invention discloses a control method and device of a battery management system, equipment and a storage medium. The method comprises the following steps: acquiring target allowable output power of a battery pack in the battery management system; under the condition that the target allowable output power is greater than or equal to a preset power threshold value, acquiring initial request power of a target load corresponding to the battery pack; under the condition that the initial request power is greater than the target allowable output power, determining the target request power of the target load based on the target allowable output power; the battery management system is controlled to discharge at the target request power, the target request power of the target load is determined based on the target allowable output power, adjustment of the output power of the battery management system is further achieved, and real-time closed-loop response between a battery pack in the battery management system and the target load is further achieved; and the reliability and intelligence of the battery management system are improved.
Description
technical field [0001] The present application relates to the technical field of battery management systems, and in particular to a control method, device, device and storage medium of a battery management system. Background technique [0002] Power batteries are widely used in electric vehicles, electric motorcycles, electric mopeds, electric forklifts and other electric power tools. The current power battery management system responds to different battery working conditions and load requests, and its specific corresponding output only has two situations: on and off, that is, the battery output power cannot be limited according to different system working conditions; resulting in low energy utilization. Contents of the invention [0003] In order to solve the above technical problems, the present application discloses a control method of a battery management system, by determining the target request power of the target load based on the target allowable output power when ...
