Description

technical field [0001] The invention relates to a circuit switching device, in particular to a fast switching device and a switching method for battery series-parallel circuits. Background technique [0002] In recent years, with the increasingly prominent environmental and energy issues, governments of various countries have paid more and more attention to the development of new energy sources. Especially in the automobile industry, all countries have begun to vigorously develop new energy vehicles, among which pure electric vehicles and plug-in electric vehicles are the main ones. Regardless of pure electric vehicles and plug-in electric vehicles, a large number of batteries are used as the power source of the vehicle. However, due to the unavoidable differences in the process of battery manufacturing, such as differences caused by different raw materials and processing techniques, there are inconsistencies in capacity and internal resistance among different batteries.
