Abstract: A hardware?in?the?loop (HIL) testing platform of the battery management system (BMS) for hybrid vehicles is constructed based on engineering practice to support the development and testing of BMS. The hardware of the testing platform includes upper computer, real?time simulator, battery emulator, etc., the software includes RT?LAB simulation platform and automated testing software TA, and the real?time simulation model includes battery model, full vehicle model, and so on. By means of the HIL testing platform, the input signal of the BMS controller is simulated, and the output signals and the necessary input signals of the BMS controller are collected, so as to perform the verification test of the BMS strategy. The results show that the HIL testing platform can verify the reliability of the BMS strategy accurately and comprehensively, shorten the product development cycle, and reduce development costs.

Keywords: HIL testing platform; BMS; hybrid vehicle; signal acquisition; simulation modeling; verification test

電池管理系统(BMS)作为混动车的核心技术之一,直接影响到汽车的行驶里程、能耗、寿命等关键指标,具有极其重要的研究意义[1]。由于电池自身的特性,采用电池组验证电池管理系统有一定的试验条件限制。在测试电池处于极限工况下电池管理系统的控制功能时,容易出现安全问题[2?3]。采用硬件在环测试的方法对电池管理系统进行测试,能够避免这种问题,加速和简化开发流程,及早地发现设计的不足。

硬件在环(HIL)测试平台是将系统的一部分用数学模型进行仿真模拟,另一部分用真实的控制器硬件来代替,形成仿真闭环回路。其优点是使得系统在一个尽可能逼真的模拟环境中进行运行和测试[4?6]。一套完整的BMS硬件在环测试系统可以加快开发流程,提高产品的可靠性、稳定性和安全性[7?8]。……
