Abstract: The mission of "carbon peaking and carbon neutralization" is forcing China's energy industry transform to sustainable development. At the same time, the technology of new energy vehicles has been continuously upgraded, and the supporting facilities related to EV charging and battery swapping services have been gradually improved, which has jointly promoted the rapid development of new energy vehicle industry of China. The current situation and development tendency of new energy vehicles and their charging and battery swapping technology were presented, and in allusion to the impact of grid connection of large scale new energy vehicles on the operation of distribution network it was proposed that through the way of aggregation the new energy vehicles was taken as the flexible load participating the operation control mode of interaction of vehicle and grid and the situation of application was presented. The construction progress of standard system of charging and charging and battery swapping services of China’s new energy vehicles was expounded. Finally, some suggestions were put forward for the key work of industry development.
