摘要:
电动汽车电池箱内装有锂离子蓄电池模组，电池箱通过快换锁止机构锁紧于托架上，托架固定于电动汽车上，电池箱既要满足车辆运行的安全性又要满足换电机器人频繁更换的要求。由于电池箱在电动客车行驶过程中受力工况较为复杂，本文基于计算机辅助分析(CAE)技术，对公司生产的电动商用车电池箱箱体进行不同工况下的力学强度分析，并进行优化设计，既达到了减轻重量及成本的要求，又保证了车辆运行过程中的安全性能。通过青岛、天津、南京等多地装有该快换电池箱的纯电动商用车的实际运行表明，CAE方法设计出的快换电池箱能满足车辆运行安全性的要求，为以后电动汽车快换电池箱的设计改进提供理论依据，一定程度上促进了电动汽车行业的发展。>The battery box of electric vehicle equipped with lithium ion storage battery module, the main bearing mechanism, and through the quick lock mechanism is locked on the battery box’s bracket, which is fixed on the electric vehicle, not only satisfying the vehicle operating’s safety, but also satisfying the requirement of electric robot’s full- automatic frequent transposing. Owing to the fact that electricity stress condition is comparatively complex in the process of electric motor coach running, this article is based on the computer auxiliary analytical technique, strength analysis under different conditions company procreative the battery box of electric motor coach, and optimal design, then not only achieve the requirements and reduce the cost, but also guarantee the vehicle operating’s safety performance. According to the practical action of pure electric vehicle which equipped with this quick change of battery box in Qingdao, Tianjin, Nanjing etc., through CAE method designs quick change of battery box satisfy the requirement of vehicle operating’s safety. The method provided theoretical basis for the design and improvement of quick change battery box of electric vehicle design in the future, and promoted the development of electric vehicle business.
