Abstract

Diesel engine lithium-ion battery hybrid vehicles are attracting attention because the energy consumption during their operation and exhaust emissions can be reduced considerably. However, a reasonably accurate method of designing the engine power and battery energy has not yet been proposed, although the above-mentioned type of traction system can help in realizing an environment-friendly railway vehicle. In this paper, a design method for the battery energy capacity and engine output power is proposed in the case of a control strategy in which the sum of the kinetic energy of the vehicle and the battery energy is maintained constant. The proposed method is verified by the velocity/state of charge of the battery charts obtained in experimental tests. The proposed design method can be used to develop environment-friendly railway traction systems for nonelectrified sections.
