摘　　要：研究了机械振动对电动自行车用锂离子电池的机械和电性能影响。对振动测试后的电池进行失效分析,发现电池故障主要表现为壳体承受应力不够、无输出电压和内部连接断裂。此外,模拟振动放电实验的结果表明,振动对容量的影响比较小。The effects of the mechanical vibration on the mechanical and electrical properties of the lithium-ion battery for electric bicycle were studied. The Failure Analysis of the battery after vibration was carded out. No withstand of casing, no output voltage and internal fracture connection were the mainly failure. In addition, the discharge under the vibration condition was tested. It shows that the vibration has a little impact on the capacity.
