This paper introduces a management system of electric bicycle charging based on mobile network, which mainly describes the overall architecture of charging system and the communication process of the system. The control side uses a master chip based on STM32F103. The software system is based on the design of the embedded realtime operating system μC/OSIIand emWin graphics libraries. This paper studies the current test module of the battery charging process. The system realizes the function of mobile payment, mobile phone monitoring charge status and full power automatic poweroff.
