Intelligent Charger Design of Electric Bicycle Based on SCM

Abstract:

In order to avoid the disadvantages of electric bicycle chargers and extend battery’s life, this paper proposed a design plan of intelligent charger based on SCM. It introduced the principle, the hardware circuit components and software flowchart in detail. According to the rechargeable battery sampling voltage and the electric current condition information, the SCM produces the appropriate PWM signal, achieves precise charge controlling of different stages, and it has the function of data displaying and overheating protection. Practice has proved that the charger can improve the charging efficiency and extend battery’s life effectively.
