摘要/Abstract

摘要：

随着全球能源结构的转变，新能源电动汽车因其在节能减排方面的优势正逐渐成为交通领域的主力军，但充电问题成为消费者购买电动汽车的顾虑。为此提出了车-车能量互济装置，在电动汽车动力电池能量不足且周围没有充电桩的情况下，可以向周围能量充足的电动汽车寻求能量补给。针对电动汽车动力电池输出电压较低，无法直接给另一辆电动汽车充电的问题，构造了二次型升压变换器及其状态方程，不仅实现了设备的轻量化，而且能够提供较宽的电压增益，满足所有电动汽车快速充电的需要。针对二次型升压变换器传统电压模式控制器的缺点，提出了一种改进的电压模式控制器，避免了传统电压模式控制器由于积分环节导致的瞬态性能和稳态性能之间的权衡问题，可以使用更少的反馈量来保证受控系统输出符合要求的直流电。仿真试验表明，当供能车的电压发生变化时，车-车能量互济装置输出电压能够快速稳定在300，500，800 V附近，并且所能提供的充电功率全部满足30 kW的快充需求。

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.

Key words: renewable energy, electric vehicles, vehicle-vehicle energy mutual aid, charging pile, quadratic boost converters, voltage mode controller
