Additionally, E c = 0. 75 E V max is assumed in this work, where E V max is the maximum energy storage capacity of the EV''s battery. It should be noted that Δ t 1 and Δ t 2 are calculated based on the maximum allowable charging power, and P max is a variable rather than a constant if E i n i t i a l ≥ E c. Therefore, the minimum charging time t c required to

Based on the predetermined ladder electricity pricing scheme used in this study, the charging piles are categorized into different sets based on the corresponding EV’s state. To reduce the dimension of the action space, the agent only makes control decisions for each set rather than for each charging pile individually.
