Electric car industry at home and abroad is in a boom period, and therefore its supporting charging facilities have also been unprecedented attention. As an important part of the industry chain, electric car charging stations have a very big future prospects. Charging system for charging pile, it must be able to provide users of electric vehicles safe, reliable, convenient and efficient charging service. Based on the needs of electric vehicle charging station billing management system, the use of IC card reading and writing subsystem design. From a practical point of view, making the design of the IC card reader subsystem is not only user-friendly to use, and with other charging stations with applicable. Program not only for the IC card reader subsystem hardware framework is described in detail, but clearly the function of each part, to provide the corresponding IC card reading and writing as well as the accounting scheme. According to the basic operations of electric car charging pile request, using the most popular consumer CPU card as a financial intermediary. By charging point system design software and hardware to provide consumers with a set of credit card charge consumer services. The first step, according to the application requirements of the project for the CPU card card file system design. Planning the internal CPU card security system and file access process and to determine the terminal card information reader interacts with the design of the CPU card appli
