6 FAQs about [Tram energy storage tower]
Why is energy storage system on trams important?
The energy storage system on the trams has been convinced to meet the requirements of catenary free tram network for both at home and abroad. This technology improves the technical level of domestic tram development greatly and promotes the development of China’s rail tram industry.
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.
What is the energy storage system of catenary free trams?
On the basis of the research on the energy storage system of catenary free trams, the technology of on-board energy storage, high current charging and discharging and capacity management system has been broken through. The trams with the energy storage system have been assembled and have completed the relative type tests.
Can supercapacitor-based energy storage system be used on trams?
