摘要
当地铁车辆在供电出现故障或者所处轨道无供电装置时,通过车辆自带的蓄电池作为动力电源,可实现段场内及正线AW3载荷23‰坡道上的正常启动,完成转轨或者自牵引到最近站点,减少救援工作量。目前,大部分地铁车辆采用镍铬电池作为辅助电源,受体积、重量以及放电率等因素的限制,难以在正线线路上作为牵引动力进行批量应用。锂电池作为一种新型动力电源,在体积、重量、环保性、放电率等方面具有突出的优点,其在地铁车辆上的实际应用领域具有广阔的市场前景。
The lithium battery can be used as power source under the condition of power supply failing or at the location without power supply, realizing starting in 23‰ ramp with AW3 load, completing transition or self-traction to the nearest station, and reducing rescue operation. At the current, the nickel-chromium battery is mainly used as the power source of subway vehicles, due to its volumetric, weight and discharge rate, it is difficult to be batch applied in the line. As a new type of power supply, lithium battery has many advantages in terms of volume, weight, environmental protection and discharge rate, which has a broad market prospect in the practical application field of subway vehicles.
