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 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)
By the end of 2020, the units in operation (UIO) of public charging piles in China was 807,000, and the number of new charging piles had increased significantly. With the continuous development of the scale market of new energy vehicles, the number of public charging infrastructures in China have grown rapidly.
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.
As the distribution shows, the proportion of new energy private cars with an average monthly charging times of less than 5 was 53.4%, which is 8.22% higher than that in 2019 (Fig. 5.11) mainly due to a higher proportion of PHEV private cars with an average monthly charging time of less than 5 than 2019 (Fig. 5.13).
