The BMS test system is used for the testing of the power battery management system (BMS) in the R & D, design, and production stages. Battery parameters such as cell voltage, cell current, temperature, total voltage, total current, and insulation resistance can be simulated. With the output and detection functions of digital signals, analog signals, digital signals, charging interaction signals, etc. It can be customized for the testing needs of different products such as controller (BMU), collector (CSC), insulation monitoring module (IMD), current sampling module (CSU) and so on. The BMS test system software platform includes test process editing, report generation, MES interaction and other functions, and can be customized to develop the host computer interface
