BMS stands for Battery Management System. It is a device to monitor the state of energy storage batteries, mainly for intelligent management and maintenance of each battery unit, preventing the battery from overcharging or over-discharging, extending the service life of the battery and monitoring the state of the battery.

Battery Testing Equipment plays a crucial role in supporting the research and development of battery products, driving technological innovation, and ensuring product quality. It is a key strategic instrument in promoting basic research on battery materials and supporting the development of the battery industry.

Electric vehicles (EVs) have always been regarded as the next generation of automobiles. With the rise of EVs, the demand for charging piles is also set to experience large-scale industry development.. The European standard AC charging pile needs to integrate an AC charging interface, a human-computer interaction interface, electrical safety design and protection. It cooperates with the vehicle-mounted charger of electric vehicles to provide multiple charging methods such as card swiping and mobile payment, requiring a high degree of integration of human-machine interaction, control, measurement, and safety protection units.
