回馈制动电机在电动自行车中的应用

本文旨在应用电机回馈制动原理提高电动自行车的续航里程。电动自行车上装设的回馈制动系统主要由电动机系统、升压斩波电路、蓄电池系统、控制系统4个部分组成。控制系统负责输入外界信号,由升压斩波电路完成驱动与制动两种工作状态的转换。驱动状态时,电机作为电动机,蓄电池提供电能;制动状态时,电机作为发电机,蓄电池吸收动能。电动自行车回馈制动系统可有效利用自行车刹车时的残余动能,不仅节约能耗,还提高了电动自行车行驶的安全性。

The Application of Regenerative Braking Principle in Electric Bicycles

In the research,we tried to improve the endurance of electric bicycles by using regenerative braking principle.The regenerative braking system consists of electric bicycle motor system,boost chopper circuit,the battery system and the controlling system.The boost chopper circuit,which serves as a bridge between two different working states,is the core of the whole system.When working in the braking states,the system converts the motor to a generator,which fully utilizes the energy loss.Furthermore,the installing of regenerative braking-driving system can improve the driving safety of electric bicycles.
