【Abstract】 The imperfect construction of electric vehicle charging infrastructure has become an important factor restricting the development of electric vehicles. Facing with the high construction cost of electric vehicle charging piles and the difficulty of supervision, an electric vehicle charging solution based on NB-IOT under the background of "Internet +"is proposed. The problems existing in the current charging system are analyzed.The system framework that containing smart charging pile and cloud platform management is provided. The functional requirements of the system are defined. The hardware and software design methods of the charging piles and the design ideas of cloud platform management system are expounded. The test results show that the system runs stably, which better solves the networking and supervision problems in the construction and operation of charging piles, saves the construction and maintenance costs, improves the level of charging service, and has a good application prospect.更多还原
