Tram iron battery energy storage power station

How do energy trams work?

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.

How much energy does a MTS tram use?

In MTS trams, the Ni-MH battery features rated energy and power of 18 kWh and 85 kW, respectively, while the supercapacitors' rated power output is 288 kW. The total weight of the hybrid storage system is 1646 kg, resulting in specific energy and power of 11.45 Wh/kg and 226 W/kg, respectively.

What is a hybrid energy storage system in Guangzhou Haizhu Tram?

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.

How much energy does a tram use?

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.

Does a tram have a battery pack?

A battery pack is the sole tram power supply and there is no battery charging at intermediate stations. For cases 1Up, 1Down, 2Up, and 2Down, when a tram is in the electrified zone (a zone with contact line), all tram power demands are drawn from the contact line, and also a battery pack is recharged.

Why should you choose a battery-driven tram?

This will help to reduce the required traction power, energy, and consequently battery capacity. Owing to advancements in battery technology, battery performance has been improving while the cost is going down, this keeps increasing the attractiveness of a battery-driven tram on short and idle routes.
