Embodiment 2

[0019] Existing batteries generally use a battery pack composed of multiple batteries to meet the requirements of large capacity. It uses a plurality of batteries connected in parallel to form a battery pack that meets a certain capacity requirement, and then multiple battery packs are connected in series to form a large-capacity battery that meets a certain capacity and a certain rated voltage. However, there is a disadvantage of using this method, that is, if the parameters in a single battery pack do not match, such as internal resistance, when the battery stops working, since a single battery pack is composed of multiple batteries connected in parallel, a discharge circuit must be formed in the battery pack. After a period of time, the battery capacity will drop significantly, which will damage the service life of the battery. When the parameters of each battery in the battery pack do not match, the loss will be more obvious. In order to solve the above technical problems,...
