摘要

结合电池和超级电容器的混合电存储系统的成功与这些设备的管理方式有关。本文研究了电池与超级电容器互补性在电动汽车中的最佳利用。首先，存储设备的尺寸是基于电动汽车的缩小尺寸规格。然后给出了采用频率共享策略仿真得到的各存储器件的功率波形。通过对不同滤波常数值的分析，揭示了功率共享策略对电池电流波形的变化效应。最后确定了最优滤波常数。它降低了RMS电池电流值，提高了电池使用寿命。

Optimal power sharing between batteries and supercapacitors in Electric vehicles

The success of hybrid electrical storage systems which combines batteries and supercapacitors is related to the manner how these devices are managed. In this paper, optimal use of the complementarity between batteries and supercapacitors in electric vehicles is studied. First, storage devices are sized based on reduced size specifications of the electric vehicle. Then, power waveforms for each storage device obtained by simulation using the frequency sharing strategy are presented. Different values of filter constant are therefore analyzed to show the variation effect of power sharing strategy on battery current waveforms. The optimal filter constant is finally determined. It offers reduced values of RMS battery current and enhancement of battery service life.
