摘　　要：由于纯电动汽车动力电池功率密度低、大电流充放电能力差、能量利用率低,是造成其续驶里程短的主要因素,在现阶段电池技术得不到大的突破的前提下,如何使再生制动能量回收达到最大化和提高其利用率是提高电动汽车续驶里程的关键。在保证制动的安全性和稳定性,考虑国家安全法规,结合实际的纯电动公交客车运行工况的前提下,提出了一种基于复合电源系统的再生制动力分配控制策略,搭建了模糊控制器。通过MATLAB/Simulink对制动力分配策略建模,基于ADVISOR中中国城市道路典型循环工况下对控制策略进行仿真验证,结果表明此控制策略在满足国家标准法规的前提下,有效地提高了能量回收效率,增加了电动汽车的续驶里程。Due to the low power density,poor high-current charge and discharge capabilities,and low energy utilization of pure electric vehicle power batteries,which are the main factors that cause their short driving range,how can the battery technology be made without a major breakthrough at this stage Maximizing regenerative braking energy recovery and improving its utilization rate are the keys to increasing the mileage of electric vehicles.Under the premise of ensuring the safety and stability of braking,considering national safety regulations,and combining with the actual operating conditions of pure electric buses,it proposes a regenerative braking force distribution control strategy based on a composite power system.Controller.The braking force distribution strategy was modeled by MATLAB/Simulink,and the control strategy was simulated and verified under typical cycling conditions of Chinese urban roads in ADVISOR.The results show that this control strategy effectively improves energy recovery under the premise of meeting national standards and regulations.Efficiency increases the driving range of electric vehicles.
