Under the assumption of fast charging rules (the vehicle must leave when it''s fully charged), if the parking time is longer than the expected fast charging time, the EV chooses slow charging to avoid moving the car, and the demand for slow charging piles in the parking lot increases by 1; On the opposite, the EV chooses fast charging and the ...
A possible reason is that the AC charging pile only covers a small footprint, so installing a charging pile on parking space in an urban shopping center or a large parking lot does not require major modifications to the parking space unless it involves the expansion of the existing building''s power facilities (Muratori et al., 2019). A small ...
