Description
technical field [0001] The invention relates to the technical field of simulation devices, in particular to a battery pack simulation device and an assembly method. Background technique [0002] The battery pack is the main source of power for electric vehicles. Therefore, monitoring the status of the battery pack is an important function of the battery management system (BMS). In the research and development process, battery packs are usually used as the load of the BMS. However, the battery pack is composed of many battery cells in series. Due to the physical characteristics of the battery cells, it is impossible to realize the conversion of various working conditions in a short time, such as the highest voltage to the lowest voltage. The cells output various working conditions with different voltages respectively. Under normal circumstances, the battery pack simulation device will be used in the experiment, which can quickly simulate various voltage conditions of each b...
