Design and Control of 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 the more important: the system-level integration and optimization. In this paper the authors present the design of a propulsion drive for an hybrid electric vehicle (HEV). Mathematical models of the subsystems are presented and an optimized vector control strategy is applied to the induction motor drive. Propulsion system is simulated in virtual test bedcopy program and several results are presented in different operation modes, including braking regeneration
