Design method and control optimization of an Extended Range Electric Vehicle

Extended Range Electric Vehicle (EREV) is a promising choice to overcome the limitation on the driving range of Electric Vehicle. However, its potential advantages extremely depend on the system design, especially the battery. This paper focuses on the component sizing of the energy and power of battery system, power design of R-Ext and the traction motor. The control strategy is discussed in this paper, and control parameters optimization of the EREV based on global optimization is implemented, aiming to minimizing the loss of power-train in view of prolonging battery life. A comparative analysis is given to assess the optimization results.
