System Introduction
The Battery Management System (BMS) is one of the most important components of a lithium battery pack. BMS not only monitors battery voltage, current, temperature and other parameters in real time, but also takes into account leakage detection, thermal management, battery balancing management, alarm reminders, SOC calculation, SOH status reporting and other functions during battery charging and discharging, so that the battery is always in a safe and controllable charging and discharging process, greatly improving the cycle life of the battery during actual use. Therefore, each BMS manufacturer attaches great importance to the detection of BMS research and development, testing, production and other links.
Referring to the new national standards such as GB/T 34131-2023 "Battery Management System for Power Energy Storage" and GB/T 38661-2020 "Technical Conditions for Battery Management Systems for Electric Vehicles", Jinkaibo has launched the KC-BMS test system based on years of testing experience in the new energy industry. It can be widely used in BMS manufacturers, power vehicles and energy storage manufacturers, power tool manufacturers, scientific research and third-party testing institutions, etc. It can quickly meet the FCT testing of BMS production line PCBA, BMS research laboratory EOL functional testing, BMS aging testing and other types of BMS project testing needs. The BMS test equipment realizes modular and standardized design, and can realize rapid batch standardized production, which can meet more than 90% of BMS testing needs on the market.
Test function
BMS Test Items | Test Method |
State detection accuracy test | Adjust relevant parameters such as temperature, current, single cell voltage, total voltage, insulation resistance, etc., compare the standard values with the parameters obtained by the battery management system (BMS), calculate the BMS temperature, current, single cell voltage, total voltage, insulation resistance measurement errors and the maximum, minimum and average values of the errors to obtain the accuracy of each parameter. |
SOC accuracy test | Adjust the battery simulator to simulate according to the battery test condition curve. BMS estimates the battery SOC capacity based on the detected data to test the SOC accuracy of BMS. |
Battery Diagnostic Test | Inject faults into the BMS, such as: battery cell over-voltage or under-voltage or battery cluster over-voltage or under-voltage, battery cell or battery cluster voltage consistency deviation, battery reverse connection, battery cluster overcurrent, cell temperature too high or too low or consistency deviation, voltage sampling line failure, temperature sampling line failure, etc., to detect the fault diagnosis function of the BMS |
Insulation resistance test | Adjust the insulation resistance parameters and obtain the insulation resistance measurement value of the BMS to determine whether it is qualified |
Communication test | Test the communication function of each communication port of BMS |
Control strategy testing | Including control strategy testing such as charging strategy and temperature management strategy to detect whether the control measurement of BMS meets expectations |
Electrical suitability test | Set the auxiliary power supply voltage to be higher or lower than the normal operating voltage to check whether the working response of the BMS system meets expectations. |
Insulation withstand voltage test | Testing the insulation performance of BMS |
Custom Tests | Users can customize test tasks according to their needs. |
