As shown in Fig. 5.2, by the end of 2020, the UIO of AC charging piles reached 498,000, accounting for 62% of the total UIO of charging infrastructures; the UIO of DC charging piles was 309,000, accounting for 38% of the total UIO of charging infrastructures; the UIO of AC and DC integrated charging piles was 481.
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 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 demand for slow charging piles is only 18. Its total number is 30. There is a reduction of 80% compared with the 153 charging piles obtained from the charging demand forecast. Assume that the time cost of electric vehicles to queue or transfer to a new charging station is the same as the time cost of fuel vehicles.
Therefore, the initial trial construction proportion of fast charging piles in the area is 3%, the proportion of slow charging piles is 6% and the total proportion of charging piles is 9%, which are as shown in Table 1 below. Table 1. The proportion of charging pile demand and construction.
Therefore if the charging piles are built in the parking spaces with a fixed proportion, the time cost of GVs will be greatly increased in the promotion of actual policies, which will be unfavorable to the construction of EV charging piles in public opinion. 5.2.3.
