Description

technical field [0001] The present application relates to the battery field, and more specifically relates to a battery management system. Background technique [0002] With the development of energy storage technology, there are more and more types of battery packs, such as lithium iron phosphate battery packs, ternary lithium battery packs, etc. These different types of battery packs have different discharge and charge characteristics. When different types of battery packs are directly used in parallel, it is easy to cause overcharging or over-discharging of the cells in the battery pack, thereby causing safety problems. Contents of the invention [0003] In view of the above, it is necessary to provide a battery management system for controlling different types of battery packs. [0004] A battery management system for controlling charging and discharging of a battery pack, the battery management system comprising: [0005] At least two battery packs, the battery pac...
