Currently, some experts and scholars have begun to study the siting issues of photovoltaic charging stations (PVCSs) or PV-ES-I CSs in built environments, as shown in Table 1.For instance, Ahmed et al. (2022) proposed a planning model to determine the optimal size and location of PVCSs.
If two vehicles arrive, one can get power from the battery and the other from the grid. In either case, the economics improve because the cost of both the electricity itself and the demand charges are greatly reduced. 3. In addition, the costs of batteries are decreasing, from $1,000 per kWh in 2010 to $230 per kWh in 2016, according to
