| Abstract: | In this study, a system model, which is controlled by battery-chargeable current, is established for series hybrid electrical vehicles via transmission energy balance. Meanwhile, an equivalent mathematical model is developed using minimal energy-consuming as an objective function. By setting relevant parameters and demonstrating two frequent driving conditions, a vehicle simulation is conducted based on an optimization strategy on instantaneous charge balance. In comparison with simulation results from the aforementioned strategy and power tracking strategy, it is indicated that the instantaneous optimization strategy can more effectively enable vehicles＇battery charge balance in the driving process. |
