摘要
电池管理系统(BMS)是电动汽车能量管理的重要部分,它提供整车控制策略的重要参数,由于电池管理系统工作于电动汽车恶劣的电磁环境之中,所以提高BMS的抗电磁干扰性能对于保证整车的安全可靠运行至关重要。基于长安中混电动车平台,分析了车内电磁环境及其对BMS的耦合干扰机理,并研究了BMS的有效电磁兼容性设计技术,重点提升了BMS的抗干扰性能。试验结果表明,经优化设计后的BMS能良好地适应电动车复杂的电磁环境。
The battery management system（BMS） is an important part of the electric vehicle energy management. It provides important parameters of the vehicle control strategy. However, BMS works in an complex electromagnetic environment of the electric vehicle, so improving the anti-electromagnetic interference performance of the BMS is extremely essential to guarantee the safe and reliable operation of the vehicle. Based on hybrid electric vehicle （HEV） platform of Changan Automobile Co., Ltd, the electromagnetic environment of HEV and its coupling mecha- nism to BMS are researched. By the EMC optimization design the anti-electromagnetic interference performance of the BMS is enhanced. Results show that the optimized BMS can be good adaptation in electric vehicle complex e- lectromagnetic environment.
