Design of Intelligent Charging Access System for Home Appliances

In order to realize intelligent charging of electric equipment in the circumstances of Smart Grid, such as sweeping robots, inspection robots and automatic guided vehicles, this paper designs a new intelligent charging access system using intelligent outlet technology and wireless charging technology. Firstly, the paper illustrates the disadvantages of existing charging mode, including low-level automation and poor security. Then, this paper gives a general introduction of the new system for the above drawbacks and a detailed description of its hardware and software design. Furthermore, as for hardware facilities, the modular design is adopted, including intelligent outlet, high-frequency power supply, transmitter, receiver and on-board charger. Moreover, to realize intelligent real-time control, it takes advantage of the WiFi communication technology to reduce the difficulty and cost of intelligent access of terminal equipment. Meanwhile, with the adoption of the twostage circuit status monitoring and abnormality judgment, the system security is improved effectively. In the last part, the paper focuses on the introduction to working flow of the system. Keywords—smart grid; intelligent power; access; wireless power transmission
