With the continual progress of charging technology, the overall charging power of public charging piles has steadily increased. In the past three years, the average power of public DC charging piles has exceeded 100 kW to meet the requirements of long range and short charging duration of electric vehicles.
The configuration of public AC charging piles has changed, i.e., from 7 kW AC charging pile to 20 kW/40 kW three-phase AC charging pile. The available charging powers of DC charging piles include 30, 60, 120, 240 and 380 kW (Fig. 5.4). Source China Electric Vehicle Charging Infrastructure Promotion Alliance (EVCIPA)
With the market-oriented reform of grid, it's possible to supplement private charging piles to meet the excessive charging demands of EVs . Shared charging means that private charging pile owners give the usufruct of charging piles to grid during the idle period .
By 2021, the number of private charging piles reached 1.47 million, accounting for 56.2% of the charging infrastructures in China. Source China Electric Vehicle Charging Infrastructure Promotion Alliance (EVCIPA) UIO of charging infrastructures in China over the years. The number of new charging piles has increased significantly.
The (44), (46), (47), (48) respectively represent the constraints of regional capacity, fast and slow charging capacity of charging stations and the capacity of shared charging piles. Constraint (49) ensures that the utilization rate of shared charging piles is positive.
Considering that the quantity of served EVs in the initial planning period in this paper is about 25 thousand, the CDs can be low in non-charging hotspot areas, thus, the minimum number of charging piles N p, min CS is limited to 2; The maximum number of charging piles N p, max CS is limited to 50 considering the costs and spatial factors.
