If the growth rate of private charging piles or public charging piles can be maintained, then the ratio of vehicles to piles in an ideal state will be 1:1. It will be realized in 2030, and the charging of new energy vehicles will become easier and easier.
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.
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.
With the development of new energy vehicles, charging piles and charging stations have been continuously constructed. Compared with research on new energy vehicles, especially pure electric vehicles, there are relatively few researches on charging piles.
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)
