【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.更多还原
