The continuous growth of sales of new energy vehicles and the low distribution rate of public charging piles have formed a group of contradictions between insufficient supply and demand. The problem of difficult charging must be solved as soon as possible to accelerate the popularization of new energy vehicles. The design is a smart charging maintenance vehicle. The scheme design is mainly concise, the function design is greater than the form, the overall function division is clear, and the shape is round and fashionable. It is mainly based on automatic driving, and the central control screen can be folded, which is convenient for personnel to debug parameters and can switch between manual driving and automatic driving. The design is equipped with a charging chamber, a maintenance chamber and a staff member. Among them, the charging bin is equipped with a charging gun to meet the emergency fast charging of vehicles, and the maintenance bin is equipped with maintenance tools and operation guidelines, which can solve most vehicle failure problems. Finally, the design is equipped with intelligent APP interaction. Users can call the nearest intelligent charging vehicle remotely through APP, and at the same time feedback vehicle problems and upload them to the background.
