Das et al. proposed a real-time regulation method for the coordinated charging and discharging of EVs based on a dynamic planning method that takes into account the cost of EVs and the operational needs of the grid, effectively reducing the charging cost of EV users and alleviating the pressure of the grid .
However, in some markets characterised by widespread availability of home charging (due to a high share of single-family homes with the opportunity to install a charger) the number of EVs per public charging point can be even higher. For example, in the United States, the ratio of EVs per charger is 24, and in Norway is more than 30.
