Description

technical field [0001] Embodiments of the present invention relate to the technical field of battery management, and in particular, to a battery management system. Background technique [0002] With the gradual rise of agricultural drones, the demand for power of drones is also increasing day by day. The increase in power means an increase in the number of batteries in the battery pack, and due to limitations in technology and product structure, there are not many multi-battery management solutions for drones at present. [0003] At present, for the management of the battery pack formed by connecting multiple batteries in the UAV, each battery in the battery pack is often managed independently through the UAV microprocessor to obtain information such as current, voltage, and temperature corresponding to each battery, and then determine each battery. Battery power and adjust the charging and discharging of different batteries. [0004] However, in the existing management te...
