Tram with energy storage is the application of energy storage power supply technology, the vehicle itself is equipped with energy storage equipment as the power source of the whole vehicle.
At present, new energy trams mostly use an on-board energy storage power supply method, and by using a single energy storage component such as batteries, or supercapacitors.
The characteristics of the energy storage equipment of the tram, which is the tram power supply system, will largely affect the performance of the whole vehicle. Since there is still a lack of a single energy storage element with high power density and energy density to meet the vehicle operation requirements [ 6, 7 ].
The greater the distance between stations, the greater the demand energy. The first interval has the largest distance and maximum energy consumption. If the recovered braking energy is not included, the energy consumption is 7.012 kwh. Fig. 3. DC bus demand energy curve. The tram adopts the power supply mode of catenary free and on-board SESS.
The tram adopts the power supply mode of catenary free and on-board SESS. The whole operation process is powered by a SESS. The SESS only supplements electric energy within 30s after entering each station. The power supply parameters of the on-board ESS are shown in Table 2. Table 2. Power supply parameters of on-board ESS.
The optimal HESS has less mass, size, cost and minimum charging state than original one in Guangzhou Haizhu tram. A hybrid energy storage system (HESS) of tram composed of different energy storage elements (ESEs) is gradually being adopted, leveraging the advantages of each ESE.
