A proposal for the propulsion system of a series hybrid electric vehicle

Hybrid electric vehicles, HEV, are an attractive opportunity to use new energy sources in road transportation, not only to minimize fuel consumption but also to reduce air pollution. Efforts are being made to improve the HEV electrical subsystems, such as electric motors, power converters, electronic controllers, energy management units, batteries, and, more importantly, the system-level integration and optimization. This paper pretends to contribute in the improvement of the hybrid drive-train configuration applying a new motion system, the joint system, JS. In this article the authors show the possible application of JS, in a simplified HEV model with series configuration. An optimized vector control technique is applied to the JS propulsion drive to enhance the HEV performance. The performance of the series HEV model with JS power-train has been checked by simulation.
