Hybrid electric trams equip with additional on-board energy storage devices to improve the performance of power sources. Both of optimal energy management and velocity control are important to maximum the energy efficiency for catenary-supercapacitors
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).
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.
Abstract: This article focuses on the optimization of energy management strategy (EMS) for the tram equipped with on-board battery-supercapacitor hybrid energy storage system. The purposes of the optimization are to prolong the battery life, improve the system efficiency, and realize real-time control.

A further economic feasibility on the single ESS installation at Shalesmoor was conducted to illustrate the potential merit of incorporating EVs into the energy storage system on the tram network. The EV batteries are …
In this paper, a self-adaptive multi-mode dynamic proportional control strategy for hybrid-energy-storage tramcar is proposed. With battery life and system effi.
This paper explores the typical energy use in light rail systems and explores the utilization of the dc rail supply to charge EV''s parked in `park-and-ride'' facilities trackside. In addition, the V2G aspect of the system could allow the EV battery to form an energy supply to assist the tram / train during acceleration and accept the regenerated ...
Energy management in Siemens ''Combino Plus'' multimodal tram vehicles when rolling on non-electrified sections: (I) acceleration power is supplied by supercapacitors; (II) cruising/coasting power is supplied by batteries; (III) regenerative braking recharges].
The purpose of this paper is to explore the concept of utilising stationary Electric Vehicle (EV) batteries in a P&R facility to act as lineside energy storage for urban dc tram systems as a method of reducing the capital expenditure required to achieve operational efficiency improvements in the tram system.
