摘要
为了研究在电动车制动能量回馈下超级电容器的储能特性,本文提出了一种模拟制动能量回收的实验方法。通过该实验方法测量了不同的超级电容初始电压下其回收的制动能量,获得了超级电容初、末电压之间的关系,进而得到超级电容初始电压与其制动能量回收效率之间关系的模型,通过该理论模型获得了系统达到最大效率点时所对应的初始电压。并用MATLAB/Simulink验证了该实验方法的有效性,为超级电容最大化回收制动能量提供了参考依据。
In order to study the super-capacitor energy storage characteristics under the braking energy feedback of the electric vehicle, an experimental method for simulating the brake energy recovery is proposed in this paper. The braking energy recovery was measured under the different super capacitor initial voltage by this experimental method, and then the relationship between the initial voltage and the end voltage of the super-capacitor was obtained. The rela- tionship model between the super-capacitor initial voltage and the brake energy recovery efficiency was developed theo- retically. And the initial voltage corresponding to the maximum efficiency of the system was obtained. This experimental method was evaluated by the MATLAB/Simulink simulation mode, thus it provides a reference for the super capacitor to maximize the recovery of braking energy.
