Background technique

At present, electric vehicle charging solutions often rely on charging piles, and the construction of charging piles often requires both occupying valuable land resources and reporting for approval in advance. The procedures are very complicated. In the completed site, due to insufficient considerations in the early planning, , May not be able to be arranged well, which has caused great obstacles to the development of electric vehicles. There are also some mobile charging robots, which only put forward some rough concepts, and there is still a long way to go before they can land.

Because the current fixed charging piles cannot be moved, when building a parking lot for a motor vehicle, some charging piles must be equipped according to a certain proportion of electric cars that may be parked, occupying a large area. Moreover, each charge requires manual insertion and removal of the charging gun and payment after charging is complete. If the owner does not pull out the charging gun in time after the charging is completed, freeing up the parking space, it will affect the charging of other electric vehicle owners, reduce the utilization rate of the charging pile, and the user experience is poor. This phenomenon makes the charging of electric vehicles impossible, which is not conducive to the promotion of electric vehicles. In addition, charging during the day's peak price of electricity also has to face relatively high electricity costs, increasing the overall cost of electric vehicles.
