摘　　要：随着新能源汽车的广泛应用,新能源汽车事故频发,很多起事故发生在车辆正常行驶或者停放的过程中,事故存在极大的不可预测性和安全风险。电动汽车用动力电池热扩散测试项目的主要目的是验证电动汽车整车或者电池系统应对动力电池单体发生热失控时,能否有效保护驾乘人员安全或者安全逃生的能力。对电动汽车动力电池热扩散测试的项目来源、国内外标准法规要求、研究进展进行了分析介绍,并提出了基于热扩散项目未来的研究方向。New energy vehicle fire accidents occur frequently with the wide application of new energy vehicles,and many accidents occur during the normal driving or parking.These accidents have great unpredictability and safety risks.The main purpose of the traction battery thermal propagation test for electric vehicles is to verify whether the electric vehicle or the battery system can effectively protect the occupants’ safety or safe escape when the battery cell is out of control and thermal runaway is happened.In this paper,the objectives,domestic and international standards and regulations,and research progress of thermal propagation test are analyzed and introduced,and the future research direction based on thermal propagation is proposed.
