Abstract:With the rapid development of electric vehicle technology, the problem of cascade recycling of retired power lithium batteries has become increasingly prominent. In the field of automobile manufacturing, AGV lead-acid batteries are likely to be replaced by retired power lithium batteries. Based on the manufacturing system, SGMW has carried out the research on the hierarchical application of lithium battery in the factory AGV. Taking an AGV power supply as an example, this paper mainly carries out the design of battery pack scheme, battery management system (BMS) and electrical design selection, and applies it to the actual vehicle verification. Through the above research, the feasibility of AGV cascade utilization of retired power lithium batteries is verified, and the design and transformation of AGV cascade utilization of retired power lithium batteries is realized.
Key words:battery echelon utilization, retired power lithium battery, AGV power supply transformation
1 引言
锂离子动力电池被世界科学家称誉为“21 世纪洁净的环保新能源”,具有极大的发展潜力。随着国家对新能源电动汽车的规划和扶持,锂电技术不断创新和飞速发展,同时也存在废旧电池的处置问题。据中国汽车技术研究中心预测,2018~2020年全国累计报废动力电池将达12万~20万吨,而到2025年,这一数字累计将超过75万吨,市场规模超过百亿元[1]。从环境保护和资源利用方面来看,对废旧锂电池的回收再利用问题亟待解决。2018年,工信部发布《新能源汽车动力蓄电池回收利用管理暂行办法》,明确指出由汽车生产企业承担动力蓄电池回收的主体责任。由行业标准可知,新能源汽车动力电池衰减至标称容量的80%,需从车上退役。此退役动力电池的容量和功率仍然可以適用于一些低动力性能要求场合,可对其进行梯次利用。……
