摘　　要：为了配合锂离子电池在无轨电车上的应用,提出了一种针对无轨电车运行环境的锂电池管理系统,能够对车载电池进行故障诊断、分级报警和优化充电.本文主要分析了无轨电车环境下电池运行模式的特点,针对原有铅酸电池的使用和管理问题,提出了更加优化合理的锂离子电池使用方法和控制策略,就电池的故障分级、电池荷电状态(SOC:State of Charge)估算、电池有效利用容量区间、充电电流的计算方法进行了深入研究,提出了多种特殊处理方法,较好配合了锂离子电池在无轨电车上的安全高效使用.For the lithium-ion battery application on trolley bus, this paper presents a lithium battery management system for the trolley bus, this system can not analyze the battery fault condition online and tell the driver by graded alarm, but also can optimize the charge process. This paper analyzes the battery operation mode on trolley bus. Regarding the use and management issues of the original leadacid batteries, the paper also puts forward a more optimal and rational use and control strategy of the lithium-ion battery for trolley bus. Specifically, the paper carries out study in depth on the battery fault classification, SOC estimation, battery efficient use of capacity range, the charge current method in calculation, and also puts forward a variety of special treatment methods to coordinate with the safe and efficient use of lithium-ion battery on trolley bus.
