Electric rail transit systems are large consumers of energy. In trains with regenerative braking capability, a fraction of the energy used to power a train is regenerated during braking. This regenerated energy, if not properly captured, is typically dumped in the form of heat to avoid overvoltage. Finding a way to recuperate regenerative braking energy can result in economic as well as technical merits. In this comprehensive paper, the various methods and technologies that were proposed for regenerative energy recuperation have been analyzed, investigated and compared. These technologies include: train timetable optimization, energy storage systems (onboard and wayside), and reversible substations.Index Terms-Onboard energy storage, regenerative braking, reversible substation, wayside energy storage.

“…There are already light rail vehicles (LRV) such as short distance metro trains or trams with on-board energy storage devices in service (see, e.g., [1]). However, the concept of the catenary-free operation of medium sized electric multiple units (EMU) with on-board energy storage devices for intercity operations remains mostly in the prototype phase or short distances [2]. An exception is a battery-driven train operated by East Japan Railway Company.…”

Catenary-free operated electric trains, as one of the recent technologies in railway transportation, has opened a new field of research: speed profile optimization and energy optimal operation of catenary-free operated electric trains. A well-formulated solution for this problem should consider the characteristics of the energy storage device using validated models and methods. This paper discusses the consideration of the lithium-ion battery behavior in the problem of speed profile optimization of catenary-free operated electric trains. We combine the single mass point train model with an electrical battery model and apply a dynamic programming approach to minimize the charge taken from the battery during the catenary-free operation. The models and the method are validated and evaluated against experimental data gathered from the test runs of an actual battery-driven train tested in Essex, UK. The results show a significant potential in energy saving. Moreover, we show that the optimum speed profiles generated using our approach consume less charge from the battery compared to the previous approaches.

“…Thermal management of lithium-ion batteries is a specific practical challenge because operation in hot and cold temperatures accelerates aging and battery performance is decreased in cold conditions [63,64]. In the shadow of lithium-ion batteries, other more advanced battery chemistries are being developed [65,66]. Some of them hold a lot of promise, such as lithium-sulfur and metal-air batteries, but the development from the concept level chemistries to the actual real size battery system takes a lot of time, even more than ten years [45,67,68].…”

Overview of Powertrain Electrification and Future Scenarios for Non-Road Mobile Machinery

et al. 2018

Powertrain electrification continues to be a growing trend in vehicular applications. Electric powertrains have numerous advantages over traditional mechanical and hydraulic powertrains but there are still important challenges to overcome for long-term commercial success. This research presents a technological assessment of present and future developments of powertrain electrification in non-road mobile machinery (NRMM). The challenges and opportunities of NRMM electrification are described in detail. The trends and drivers related to technological development such as regulations, policies and market development are analyzed, and technology enablers are highlighted. Future scenarios are formulated based on the prevailing trends and drivers, development of key components, scientific literature and status of the non-road mobile machinery industry. Some recommendations are also given in relation to the development of hybrid and electric powertrains for NRMM. The key findings of this research indicate that the electrification of NRMM is slowly started and the progress is demonstrated by hybridization of some specific, successful mobile machines. In short-term, high component and technology development costs remain the main barrier for higher adoption of electric and hybrid powertrains. In the long-term scenario, many NRMM can operate autonomously and powertrain electrification has become mainstream technology.
