AI Technical Summary
The problem with charging difficulties lies in the fact that users cannot find available charging stations in the corresponding areas, and the initial investment for deploying charging stations on a large scale is too large.
By analyzing user-initiated charging pile deployment requests and the actual number of electric vehicles, we can divide the area into zones and analyze candidate locations. We can then calculate the usability coefficient and the number of users to optimize the number and location of charging piles to match the actual needs of users.
While reducing deployment costs, we must ensure the rationality of charging pile deployment and improve the user experience.
