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.
Trams with energy storage are popular for their energy efficiency and reduced operational risk. An effective energy management strategy is optimized to enable a reasonable distribution of demand power among the storage elements, efficient use of energy as well as enhance the service life of the hybrid energy storage system (HESS).
As the sole power source of the tram, the battery pack can supply power to the traction system and absorb the regenerative braking energy during electric braking to recharge the energy storage system. The traction system mainly consists of the inverter, traction motor, gearbox, and axle.
