This session aims to understand and quantify the problem of inefficient use of charging stations, and explore potential solutions. The session will discuss the basic facts, including battery capacity and charging effectiveness, and analyze the spatial distribution of the problem across different cities. Finally, it will address the issue of hindering other users and propose possible solutions.
