混合动力电动车用电源热管理的技术现状

Battery cooling issues and solutions in HEVs

混合动力电动车用电源的热管理问题对车辆在各种环境下的运行性能有至关重要的影响。着重从电池散热的角度详细介绍了目前电动车用蓄电池冷却措施的研究、应用和发展状况。提出混合动力电动车电源热管理的一个发展方向是将电池内部传热特性和外部散热过程耦合分析,研制更为有效的冷却方式。

Battery thermal management system (BTMS) is essential for effective operation of hybrid electric vehicles (HEVs) in all climates. This paper introduced the research, development, production and application of cooling solutions for batteries in electric vehicles mainly from the aspect of heat dissipation of batteries. The paper proposed to couple batteries' inner heat transfer character with the external heat dissipation process, so as to develop more effective and efficient cooling methods, which was one of the possible trends of the BTMS design.
