Vehicle-vehicle energy mutual aid control strategy for electric vehicles
摘要
Abstract
With the transformation of global energy structure,electric vehicles(EVs)are becoming a trend in transportation industry due to their advantages in energy saving and emission reduction.However,the charging problems worry the EV consumers.Energy mutual aid devices are proposed for those EVs which cannot get energy replenishment from any surrounding EV charging pile when they are in low-batter state.In such a case,EVs nearby with sufficient energy can fuel those run out of power.For the problem that the output voltage of an EV power battery is too low to charge another EV directly,a quadratic boost converter and its equation of state are constructed.The converter not only lights the weight the device,but also provides a wide voltage gain to meet the need of fast charging of all EVs.To address the shortcomings of the conventional voltage mode controller of the quadratic boost converter,an improved voltage mode controller is proposed which avoids the trade-off between transient-state and steady-state performance due to the integration link of the conventional voltage mode controller.Also,the improved controller can make the controlled system output qualified DC power with less feedbacks.Simulation results show that when the voltage of the vehicle supplying power changes,the output voltage of the vehicle-vehicle energy mutual aid device can quickly stabilize around 300,500,and 800 V,and provide 30 kW charging power that can meets the fast charging demands.关键词
