Recuperation of Regenerative Braking Energy in Electric Rail Transit Systems [PDF]
, 2018 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.

Energy-optimal Design and Control of Electric Powertrains under Motor Thermal Constraints [PDF]
arXiv, 2021 This paper presents a modeling and optimization framework to minimize the energy consumption of a fully electric powertrain by optimizing its design and control strategies whilst explicitly accounting for the thermal behavior of the Electric Motor (EM). Specifically, we first derive convex models of the powertrain components, including the battery, the
