Public charging piles are charging piles built in public parking lots (garages) combined with parking spaces to provide public charging services for social vehicles. The special charging pile is the charging pile used by the construction unit (enterprise)''s own parking lot (garage) for the internal personnel of the unit (enterprise).
Charging piles are mainly divided into AC charging piles and DC charging piles. AC charging piles have a smaller body, are flexible for installation, and typically take 6-8 hours to fully charge. They are suitable for small electric vehicles and are commonly used in public parking lots, large shopping centers, and community garages.
The capacity planning of charging piles is restricted by many factors. It not only needs to consider the construction investment cost, but also takes into account the charging demand, vehicle flow, charging price and the impact on the safe operation of the power grid (Bai & Feng, 2022; Campaa et al., 2021).
Indoor charging piles should have a protection level of at least IP32 or above, while outdoor charging piles need to have a protection level of at least IP54 to ensure the safety of human bodies and charging equipment in harsh environments with wind, rain, and the need for better insulation and lightning protection.
Public charging piles are purchased by public service organizations such as government for use by any electric vehicle owner, such as public parking lots.
According to the taxi trajectory and the photovoltaic output characteristics in the power grid, Reference Shan et al.
