Hybridization of rolling stock vehicles with onboard energy storage systems in AC and DC electrification system is a realistic future trend that will transform the railway industry.
1 | Challenge: Contact wire-free, battery-powered on-board energy solution for optimizing routing in inner cities Citadis are low-floor tram vehicles from the French rail vehicle manufacturer
ABB''s Containerized Energy Storage System is a complete, self-contained battery solution for a large-scale marine energy storage. The batteries and converters, transformer, controls,
The tram mainly comprises the energy storage system, traction system, and auxiliary system, and the specific structure is shown in Fig. 1. As the sole power source of the
Since a shared electric grid is suffering from power superimposition when several trams charge at the same time, we propose to install stationary energy storage systems (SESSs) for power
This paper introduces an optimal sizing method for a catenary-free tram, in which both on-board energy storage systems and charging infrastructures are considered. To quantitatively analyze the trade-off between
The modern tram system is an important part of urban public transport and has been widely developed around the world. In order to reduce the adverse impact of the power
A tram''s hybrid power system mainly consists of an energy storage system and a motor system. The motor system is connected to the DC bus through the inverter, whose power is all from
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
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.
As a result, a high tendency for integrating onboard energy storage systems in trains is being observed worldwide. This article provides a detailed review of onboard railway systems with energy storage devices. In-service trains as well as relevant prototypes are presented, and their characteristics are analyzed.
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.
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.
To solve technical problems of the catenary free application on trams, this chapter will introduce the design scheme of supercapacitor-based energy storage system application on 100% low floor modern tram, achieving the full mesh, the high efficiency of supercapacitor power supply-charging mode, finally passed the actual loading test [ 8, 9 ].
However, the last decade saw an increasing interest in rail vehicles with onboard energy storage systems (OESSs) for improved energy efficiency and potential catenary-free operation. These vehicles can minimize costs by reducing maintenance and installation requirements of the electrified infrastructure.
