摘要
对纯电动汽车的复合电源系统结构和工作原理进行了介绍。基于MATLAB/SIMULINK平台建立了复合电源系统仿真模型,并以简单易行、最大限度保护蓄电池、提高能量回收效率为前提,为复合电源系统设计了功率分配控制策略,以此策略为基础完成了对复合电源系统的整车仿真。仿真结果表明所设计的功率分配控制策略能充分发挥复合电源的特点,在延长蓄电池使用寿命的同时提高了整车动力性。
The structure and operating principle of the compound power system in pure electric vehicle were introduced. The compound power simulation was modeled on the platform of MATLAB/SIMULINK. The power distribution strategy was designed for the compound power system predicated on its simple and easy, protecting battery and improving the efficiency of reeovering energy.A vehicle simulation for the compound power system was implemented. Simulating result demonstrated that the strategy made the characteristics of the compound power fully developed.This system not only proteeted and expanded the working life of the battery, but also improved the dynamic performance of the vehicle.
