本科论文摘 要随着我国不断推动电动汽车的发展，锂离子电池在行业的应用大幅提高。虽然如今的锂离子电动汽车的工艺水平以稳步提高，但是相关的火灾事故不断发生。我们不能否定锂离子电动汽车的普及给我们带来的益处，但可以将其的事故概率尽可能的降低，减少事故给我们带来的经济财产损失。锂离子动力汽车最为典型的是火灾事故，因为锂电池汽车相比传统燃油汽车有其特殊的特性，火灾蔓延快、控制措施少等特点使得我们不得不更加重视电动汽车的火灾危险性。本文通过查阅资料，了解锂离子电动汽车的结构及工作原理等相关知识，结合实际情况客观分析导致发生火灾的各种因素包括但不限于高压线路、电池组。根据相应原则合理划分各项指标，包括人和各种硬件以及软件，利用层次分析法和专家赋值法确定各指标的权重值，体现出最应该受到重视的关键指标，加强重视程度。再对锂离子动力汽车进行实际调查，进一步研究其火灾危险性。对锂电池进行实验可以证实电池组故障在火灾危险性中占重要地位。根据对电动汽车的火灾危险性分析，提出电池组、设计生产和消防多个方面相应的防范措施，可以最大程度的降低火灾风险，保障人民生命财产安全的同时，有利于促进锂离子动力汽车及其相行业的发展。关键词：锂离子动力汽车；火灾危险性；危险源辨识；安全评价；防范对策 Abstract本科论文With China's continuous promotion of the development of electric vehicles, lithium-ion batteries in the industry has greatly improved the application. Although today's lithium-ion electric vehicles have steadily improved their processes, related fire accidents continue to occur. We cannot deny the benefits of the popularity of lithium-ion electric vehicles, but we can reduce the probability of accidents as much as possible, reducing the economic and property damage caused by accidents. Lithium-ion power edgy cars are the most typical fire accidents, because lithium battery cars have their special characteristics compared to conventional fuel cars, the rapid spread of fire, less control measures and so on, we have to pay more attention to the fire danger of electric vehicles.This pap...
