A statistical view of public charging infrastructure for electric vehicles in China through 2021

China has installed more publicly accessible electric vehicle supply equipment (EVSE) than anywhere else in the world and this briefing, based on data through the end of 2021, highlights how China on the national level and Chinese cities are leading the world in public charger stock. The top 20 cities with the largest public EVSE stock were 35% of all public EVSE stock globally by the end of 2021 and 17 of these cities were in China. The maps below illustrate public charging availability in Chinese cities using four metrics. In addition to EVSE stock, the authors normalized charging infrastructure by geographic size, population, and EV stock. While the city rankings generally differed considerably by metric, and this underscores the need to consider a comprehensive set of metrics when evaluating public charger availability, Shenzhen was the clear leader as it ranked first in three metrics. Later this year, ICCT intends to investigate China’s public charging infrastructure development based on more recent data and to compare China’s progress with Europe and the United States, with an aim of mutual learning.
