摘要
对蓄电池、超级电容常用复合电源结构进行分析,确定蓄电池与超级电容复合电源结构,根据复合电源系统设计理念提出复合电源系统总体结构。根据原型车参数对超级电容和DC/DC变换器进行设计与选型,制定复合电源约束条件。在此基础上,设计了一种将逻辑门限值控制策略和基于车速的功率分配控制策略相结合的新的功率分配策略。在Matlab/Simulink环境下搭建复合电源功率分配策略模型,并搭建超级电容-蓄电池复合电源系统模型。在原型车路试工况和UDDS工况下对复合电源系统供能进行仿真。仿真结果表明:在此功率分配策略下,超级电容很好地起到辅助蓄电池输出功率的作用。最后根据复合电源系统总体结构,搭建复合电源系统试验平台并进行试验,验证了功率分配策略的可行性。
The composite structure of the battery and the super capacitor is analyzed,and the structure of the battery and the super capacitor is constructed. The overall structure of the composite power system is put forward according to the composite power system design concept. According to the prototype car parameters of the super capacitor and DC/DC converter design and selection,the development of composite power constraints; On the basis of this,a new power allocation strategy combining logic threshold control strategy and power-based power distribution control strategy is designed. In the environment of Matlab/Simulink,the power allocation strategy model of compositepower supply is set up and the super capacitor-battery compound power system model is set up. And the simulation of the power supply of the composite power supply system is carried out under the prototype road test condition and UDDS condition. Simulation results show that under power allocation strategy,the super capacitor is very good to play the role of auxiliary battery output power. Finally,according to the overall structure of the composite power system,the test platform of the composite power system is set up and tested to verify the feasibility of the power allocation strategy.
