摘要
对由铅酸电池与超级电容并联,并在铅酸电池与超级电容之间采用两象限DC/DC转换器控制的复合储能方式进行研究,建立其简化的等效电路模型,并从能量流的角度出发建立复合储能系统能量流模型,在Matlab/Simulink环境下对模型进行仿真计算,并在课题组搭建的汽车能量再生系统硬件在环仿真试验台上进行了试验,结果表明复合储能器能量回收率远高于单个储能器回收的能量值,并且复合储能系统的使用有利于制动能量回收与利用的优化管理。
A duplex energy storing system which consists of the parallel of lead-acid battery and ultra-capacitor combined with a two quadrant DC/DC converter was investigated. Its simplified equivalent circuit model was built, and an energy flow model of the duplex energy storing system was established based on system energy flow. The simulation was carried out under Matlab/Simulink environment, and the hardware-in-loop （HIL） test was accomplished on the regenerative braking system test bench. The result indicates that the reclaimed energy with duplex energy storing system is much larger than that of separated one, and the use of duplex energy storing system is better for optimizing management of regenerative braking.
