Tram energy storage quality control workflow

Why are trams with energy storage important?

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).

Which regenerative energy management strategy is best for a tramway?

The adaptive EMS allows better harnessing of regenerative energy than the RB-EMS. In this paper an adaptive energy management strategy (EMS) based on fuzzy logic and the optimal sizing for a tramway with a hybrid energy storage system (ESS) combining batteries (BT) and supercapacitors (SC) are presented.

How energy management strategy is used in Guangzhou Haizhu trams?

An improved PSO algorithm based on competitive mechanism is developed to obtain the optimal energy management strategy. The obtained energy management strategy has better effects in energy reduction with application in Guangzhou Haizhu tram. Trams with energy storage are popular for their energy efficiency and reduced operational risk.

Is there an equivalent consumption minimization strategy for a hybrid tram?

An equivalent consumption minimization strategy is proposed and verified for optimization. This paper describes a hybrid tram powered by a Proton Exchange Membrane (PEM) fuel cell (FC) stack supported by an energy storage system (ESS) composed of a Li-ion battery (LB) pack and an ultra-capacitor (UC) pack.

Can a hybrid tram operate without a grid connection?

This paper describes a hybrid tram powered by a Proton Exchange Membrane (PEM) fuel cell (FC) stack supported by an energy storage system (ESS) composed of a Li-ion battery (LB) pack and an ultra-capacitor (UC) pack. This configuration allows the tram to operate without grid connection.

What are the components of a tram?

This tram is firstly composed of the following elements: A Li-ion battery pack, an ultra-capacitor pack, two dc/dc bidirectional converters, tram loads, braking chopper, and energy management services. Latterly, to enhance drivability and range, a PEM FC stack and a dc/dc unidirectional converter are added, marked with star symbols in Fig. 1.
