燃油机车对环境造成的污染日益加剧,电动三轮车作为一种性价比高、维护经营成本低、节能环保的交通工具越来越受到人们欢迎.针对电动三轮车动力特点,开发了一套制动能量回收系统,并分析能量回收系统各控制参数对能量回收率的影响,扩大升压电路boost的输入电压范围、提高电机负载能力和优化充电占空比.实验表明,该系统结构简单,性能可靠,具备机械制动备份功能,且通过调节充电电流的占空比即能满足轻度制动的要求,又能获得5%以上的能量回收率.

The environment pollution caused by fuel locomotives is getting worse day by day. As a cost-effective and low maintenance cost, energy-saving and environment-friendly transport is becoming more and more popular.Thirdly, based on the dynamic characteristics of electric tricycle, a braking energy recovery system , And analyzes the influence of various control parameters on the energy recovery rate of the energy recovery system, enlarges the input voltage range of the boost circuit, increases the load capacity of the motor and optimizes the charge duty cycle.The experiment shows that the system has the advantages of simple structure, reliable performance, Brake backup function, and by adjusting the duty cycle of the charging current to meet the requirements of mild braking, but also get more than 5% of the energy recovery rate.
