Adaptive Power Management Control of Range Extended Electric Vehicle

Range extended electric vehicle can extend the cruising distance of the electric vehicle by using the range extender which consists of engine and generator, i.e. genset, without using a larger and more expensive battery pack. Equivalent fuel consumption minimization is used to design the proposed adaptive power management control strategy, such that fuel consumption is effectively reduced lower than that of the thermostat control strategy. Driver only needs to provide the approximate estimation of the traveling distance to plan the reference trajectory of SOC for discharging the battery. In order to track the reference, self-organizing fuzzy controller adaptively adjusts the equivalence factor which is used to convert the electric power usage to equivalent fuel consumption. A cost function of instantaneous fuel consumption is minimized to obtain the optimum power split between the genset and battery. Simulation results show that the proposed algorithm can improve the fuel economy and reduce the average charging/discharging power of the battery.
