Design of Controller and Router for Orderly Charging System of Electric Vehicle

With the world's attention to energy and environmental issues, the number of electric vehicle users is increasing year by year. However, the disorderly charging of electric vehicles will aggravate the uncertainty of the power grid, leading to "peak-on-peak" of residential load, forcing the capacity of power supply equipment needs to be increased and expanded, and resulting in a decline in the utilization rate of power supply equipment, which is adverse to the stable and economic operation of the power grid. Therefore, it is essential to develop a new generation of orderly charging system, which involves users, electric vehicles, AC charging piles, energy controllers, energy routers, service platforms and others. This article mainly develops energy routers and energy controllers that meet the demand for orderly charging. The energy controller is responsible for generating the local control strategy for orderly charging of electric vehicles, realizing the orderly operation of energy routers, and uploading and synchronizing the grid information and charging information of electric vehicles to the service platform in real time, to support the real-time monitoring and strategy adjustment of orderly charging of electric vehicles. The energy router (a new generation of smart meters) is responsible for the data collection of electric vehicles, energy storage, distributed power sources, microgrids, thermal storage electric heating and other new energy-consuming equipment. It has the ability of local networking and regional autonomy, and supports two ways of interacting with customers including master station and Bluetooth. The energy router and energy controller designed by the system have the advantages of small size, low power consumption, high accuracy, and strong anti-interference ability, which can meet the application of orderly charging of electric vehicles in different occasions.
