摘要
结合锂离子电池在城市轨道交通领域的应用特点,基于城轨地铁的牵引制动特性,对双动力城轨地铁牵引动力电池系统进行需求分析。针对具体的北京西郊线路工况,通过仿真计算,确定在电池系统供电运行下城轨地铁对牵引动力电池系统的能量和功率需求。在充分考虑城轨地铁功率和能量需求、轴重限制和安装尺寸等条件后,选取钛酸锂电池而确定电池系统配置,并通过计算来验证电池选型和配置的可行性。
Based on the application specialties of lithium-ion battery in the field of urban rail transit and the characteristics of traction and braking, the demand of traction power battery system is analyzed. According to the specific line conditions of Beijing western suburbs, the energy and power demand of the traction power battery system is determined. Taking account of the energy and power demand, the axle load limit and installation size restrictions, the battery system configuration is determined. And the feasibility of battery selection and allocation is verified.
