摘　　要：目前电动自行车充电过程中温度过高原因众多,其中电池问题占了40%~50%,充电问题占20%~30%。为了提高新能源电动自行车的充电效率,本文设计了一种电动自行车过温保护电路。该电路由单晶体管开关电源构成的整流滤波电路、开关电源启动电路、反馈控制、输出电路以及保护电路组成,能够有效防止蓄电池过度充电。Nowadays,there are many reasons for the high temperature during the charging process of electric bicycles,among which the battery problem accounts for 40%-50%and the charging problem is 20%-30%.In order to improve the charging efficiency of new energy electric bicycle,an electric bicycle over-temperature protection circuit is designed.The circuit includes a rectifier filter circuit composed of a single transistor switching power supply,a switching power supply startup circuit,a feedback control,an output circuit,and a protection circuit.Through the design of this paper in the electric bicycle charging process if the temperature is too high when the power can be cut off,play a safe role.
