Optical wireless technology is used to build an information network of electric vehicle charging piles. The proposal and implementation of relevant research projects have been affirmed and supported by power industry experts such as China Southern Power Grid. With the development of subsequent projects, an application system of Internet of Things information platform based on optical wireless technology in electric vehicle charging and replacing system will be gradually built. Finally realize the intelligent electric vehicle charging and replacing service network.
Charging pile is the most important facility in the electric vehicle charging system, generally fixed in the roadside or parking lot, the use of special charging interface, the use of conduction mode, to provide AC power for electric vehicles with on-board chargers, and has the corresponding communication, billing and safety protection functions. Charge an electric car by inserting a coin or buying a dedicated IC card.
With the deployment and implementation of the new energy strategy, electric vehicles will enter thousands of households. The supporting electric vehicle charging and replacing facilities have taken the lead in the construction, and will gradually form an electric vehicle charging and replacing system combining charging piles, charging stations, changing stations, distribution stations and other facilities.
