Regenerative braking in trains | Climate Technology Centre
It is possible to use regenerative braking on these high speed trains because most cars have their own electric motors, this is in contrast to trains in which only the locomotive has electric motors. The fourth generation TGVs in France, which are expected to be commissioned in 2010, will also be equipped with regenerative brakes, as will the …

Modeling of energy recovery processes in railway traction power …
To quantify the efficiency of energy recovery, one can use the value of energy Wp, obtained for this area, and an indicator of its efficiency (2) a = g W p W Π = W p N + M Δ h, which represents the acceleration useful in the recovery process and measured in Kp =a/g kWh/ (t.m) or m/s 2. Relation is the efficiency of energy recovery.

Energy management strategy to optimise regenerative braking in a hybrid dual‐mode locomotive
Embedded energy storage sources such as SCs or batteries are used to perform recovery braking. They are a more viable alternative to recover energy during braking. This option is similar to the one used in an application with a high-start/stop frequency such as elevators driven by synchronous machines [ 36, 37 ].
Review of Regenerative Braking Energy Storage and Utilization Technology in Urban Rail Transit | SpringerLink
The flywheel energy storage (FES) system based on modern power electronics has two modes of energy storage and energy release. When the external system needs energy, the flywheel acts as the prime mover to drive the flywheel motor to generate electricity, and the flywheel kinetic energy is transmitted to the load in the form …

A Design of Energy Storage System for Electric Locomotive
In this paper, we focus on a valuably consequential idea to design an energy storage system for electric locomotive which only know two requirements, required energy and required the minimum voltage. This paper is the design of batteries and supercapacitors that suitable for the system. First, select the type of batteries suitable for use and design for …
Energetic optimization of regenerative braking for high speed …
The recovered energy shows a maximum in correspondence of a 20% braking request; however, this low value of the braking request involves that the braking distance and the braking time (respectively reported in Fig. 22, Fig. 23) are quite high, beyond the acceptable limits usually considered in high-speed applications.

BNSF leads the charge on testing battery-electric locomotive
Before the pilot testing of the locomotive can begin, a battery charger will need to be designed and installed at BNSF''s Mormon Yard in Stockton later this year. While the Stockton battery charging station will provide an initial charge, the new locomotive will be designed to provide regenerative power under braking to extend its range.
