[0002] With the rapid promotion and application of medium and large-scale energy storage battery systems in many industries such as electric locomotives, vehicles, ships, microgrid systems, and power grid peak shaving and valley filling, battery energy storage technology has been rapidly penetrating various fields. At the same time, many problems that need to be overcome have also been discovered, such as long charging time, low charging efficiency, high system heat generation, overly complex cooling systems, and high construction costs. Existing energy storage battery systems usually include battery modules, thermal management systems, battery management systems, and high-voltage control systems. Due to the application scenarios and the performance and cost constraints of existing power devices, many power components are not suitable for higher voltage systems. With the gradual promotion of various energy storage application scenarios and the continuous improvement of user experience, many battery systems need to be equipped with two or more battery packs PACKs used in parallel to increase battery capacity. During the battery pack offline inspection, the battery pack needs to be charged and discharged to determine the battery capacity and charge and discharge characteristics within the battery pack. The measurement of battery capacity and charge and discharge within the battery pack requires the use of a high-voltage control box.
