According to my experience, some public charging stations located in chenghua district, Shuangliu District and Jintang County in Chengdu do not charge parking fees for charging piles near Shawan in Chengdu. These charging piles are operated for public welfare and do not charge any parking fees. However, the specific parking fee may be adjusted at any time. Please go to the official channel to confirm before you go. It is recommended that you use the map APP or search for charging pile information through websites such as car electrolysis for more details.
