[Abstract]:At present, our country is faced with serious environmental pollution and energy shortage. As one of the new energy applications, electric vehicles have high energy efficiency. The development of electric vehicle has become a global trend. As the charging equipment of electric vehicle, the research of related technology is the precondition of the widespread popularization of electric vehicle. This paper takes STM32F103ZET6 controller as the core, The embedded control system of DC charging pile is designed and implemented, which includes embedded control unit, electric energy measurement unit, IC card identification unit, temperature and humidity detection unit. The embedded control system of DC charging pile is designed and implemented in combination with the embedded control technology, such as can bus protocol and Modbus protocol, and the national standard of DC charging pile. Monitoring the charging process and displaying the charging data in real time. Firstly, the whole frame of the embedded control system of DC charging pile is designed. According to the functional requirements of DC charging pile, embedded control technology is applied. The hardware and software platform of the system is built. Secondly, according to the national grid standard, the embedded control system is designed and realized to monitor the current power network parameters in real time; from the point of view of the actual users, the payment method is selected to complete the transaction settlement; Referring to the national standard of GB/T18487.1, the embedded control system is designed and realized to monitor the environment temperature and humidity in real time. Referring to GB/T 27930, the communication protocol between the non-vehicular conductive charger and the battery management system of electric vehicle, the control of DC output unit by embedded control system is designed and realized, which is based on the human-computer interaction technology, and from the point of view of application program, the control of DC output unit by embedded control system is designed and realized. The user can realize the operation control of DC charging pile through touch screen. Finally, the prototype of DC charging pile is assembled to debug the whole machine. The basic function and related parameters of DC charging pile are tested.
