Abstract

Hybrid Electrical Storage could be considered a solution for developing sustainable transportation systems. But, are they reliable? In terms of life span, reliability, availability, and range, conventional vehicles such as cars, buses, trains are better than electrical or hybrid ones. However, traditional transportation systems present increased energy consumption and low energy efficiency. Also, the impact on environment and health could be more negative than the electrical and hybrid ones. In this paper we test if it is possible to reach a compromise between sustainability and technology constraints by developing a reliable hybrid transportation system with improved life span and range. In this sense, two designs have been implemented: a hybrid starting system for a locomotive and a hybrid storage solution for an e-bike. Both are made of batteries, supercapacitors, and the corresponding power electronics, allowing the optimal control of power flows between the system’s components and actuators. The proposed designs meet the application’s requirements in terms of functional and sustainability goals. Our analysis is based on power electronics, complexity, energy efficiency and temperature range considerations. The hybrid storage system used for starting the locomotive’s Diesel engine was tested under various real operating conditions and has shown no failure, emphasizing its performance in terms of availability, reliability and life span. The prototype for the hybrid e-bike does not depend on battery operation for short periods of time and costs less than a normal e-bike. Also, in comparison to the latter, it has better autonomy and better energy efficiency.
