Scheme for the transmission of recovery electrical energy between rolling stock with energy storages

Abstract

The market for rechargeable batteries for automotive, industrial, and other applications has grown rapidly in recent years, with battery performance (capacity and power) continuing to improve and cost to decrease [1]. This makes it possible to use storage batteries on rolling stock, which can be used on slopes and short sections of non-electrified track [2]. While traveling on electrified sections of the railway, the train charges a high-capacity battery that uses the energy to drive and power auxiliary systems. This eliminates the need for an internal combustion engine, resulting in significantly greater energy efficiency, better environmental performance and lower maintenance requirements compared to diesel trains.
