Super-capacitor technology for rail car passenger trial operation, the first time in China

The first line of Optics Valley Quantum trams was fully loaded with passengers from the Contemporary International Garden Station, marking the opening of the Wuhan Optical Valley Tram T1T2 demonstration line, which was built by the China Railway Electrochemical Bureau Group and other units.

The first operation of the first optical tower in the Quantum Valley, the telecom vehicle passenger operation, Zenghui Li, the total length of the operating line of the Wuhan Optics Valley Tram T1T2 demonstration line is 36.4km, which is the first in the country to adopt energy-type super capacitor power supply technology to achieve “all-line non-touch network”, no need to stand and charge. The super capacitor has the advantages of fast charge and discharge time, high power density and long service life, and is suitable for the operation requirements of modern trams. Optical valley of energy storage type modern tram is a fusion of high and new technology new rail transit vehicles, no traditional tram that two braids, more conducive to maintaining good various eyesores, adopting the technique of super capacitor trams, store enough electricity, without charging station, just part of the site using the passengers getting on or off automatically recharge time, 30 seconds to complete.

The Wuhan Optics Valley Tram T1T2 line was opened for trial operation. Zenghui Li was informed that the modern tram used in Optics Valley travels one kilometer and only needs 2.8 kWh. According to the large industrial electricity and electricity fee of 0.6448 Yuan / kWh the calculation is equivalent to less than 2 Yuan for running a kilometer of electricity. In addition, the tram adopts a unique energy storage structure. When driving, it encounters downhill and braking sections. The vehicle can convert kinetic energy into electrical energy and feed it back to the super capacitor storage. The recycling efficiency can reach more than 80%.

Xiangwang Wang, deputy mayor of Wuhan City, experienced the test of the first train, Zenghui Li, taking the T1T2 demonstration line as a new type of green public transportation. It will realize the integration of intercity railway, subway, BRT, conventional public transportation and other modes of transportation, and practice “traffic guidance”. The new concept of “urban development” accelerates the process of integration of production in the Large Optics Valley area and strengthens the radiation and belting effect of Optics Valley as the new center of Wuhan.
