An electric freight locomotive with red flowers hanging on the front of the car and mainly blue and white body sounded its horn in the factory area of Nanjing Iron and Steel Co., Ltd., marking the official operation of the first new type of intelligent battery pack power freight locomotive in China. The freight locomotive running this time is transformed from waste fuel locomotive. The whole vehicle is 14.9 meters long and weighs 92 tons. It uses lithium iron phosphate battery pack as power source. The maximum design speed is 20 kilometers per hour, and it can continuously travel 120 kilometers under the condition of full load of 2500 tons of goods. < p > < p > on October 10, China’s first new type of intelligent battery pack power freight locomotive was running in the factory area of Nanjing Iron and Steel Co., Ltd., Jiangsu Province. The picture shows the ceremony site. According to the introduction, State Grid Jiangsu Electric Power Co., Ltd. and the Chinese Academy of electric power research and development, spent a year and a half to overcome the technical difficulties of lithium battery DC-AC frequency conversion, permanent magnet motor locomotive calibration, precise echelon utilization of lithium battery big data, and built a supporting 300 kW fast charging DC charging pile to meet the charging demand of electric locomotive. < / P > < p > the locomotive uses lithium iron phosphate battery pack as the power source. The picture shows the staff of State Grid Jiangsu Electric Power Co., Ltd. checking the energy storage battery pack in the vehicle. < / P > < p > different from EMU trains, the intelligent freight locomotive does not need external power supply. “EMU trains run at a high speed, need stable power supply, and the investment in power grid supporting facilities is large. The power source of the locomotive is the energy storage battery, which is suitable for short distance use in large factories with low speed requirements Zhou Xianwei, project director of State Grid Jiangsu comprehensive energy service company, said. < / P > < p > in order to meet the charging demand of electric locomotives, a 300 kW fast charging DC charging pile has been built in the plant area of Nanjing Iron and Steel Co., Ltd. the picture shows the staff checking and operating the charging pile. According to Yang Bo of the new energy center of Chinese Academy of Electric Power Sciences, after putting into operation, the annual power consumption of a single locomotive is estimated to be about 390000 kwh, the annual fuel consumption can be reduced by about 172 tons, and the emission of carbon dioxide and other greenhouse gases will be about 817 tons. According to experts, this project will have a certain application prospect in mining, petrochemical, port logistics and other industries with strong demand for freight transportation.
