摘要：
The use of green energy is becoming increasingly important in today's society. As a result, electric vehicles are presently the most eco-friendly means of public and personal mobility. In order to improve the safety, energy storage capacity and service life of batteries, research on designing and testing battery characteristics and management system for new energy vehicles based on BMS system is proposed. This paper mainly studies the BMS test system platform design and SOC estimation method. A modular integrated BMS automatic test platform for electric vehicles is designed. Based on PXI hardware architecture and LabVIEW software development environment, the platform meets the test items recommended by BMS automotive industry. The results show that the actual SOC value is compared with the estimated value of BMS. The BMS under test is discharged for 100s at 440A constant current and then charged for 100s at 440A constant current. The SOC estimation accuracy of the BMS under test is detected by the test platform, and the SOC estimation errors are all within 2%, which meets the standard requirements. Therefore, Test items that meet the recommendation standard of BMS automotive industry are suitable for the factory inspection and type inspection items of BMS products for electric vehicles, and the modular platform design is conducive to the subsequent expansion and upgrading of BMS test functions. © 2023 CAD Solutions, LLC.
