The orderly charging project of the underground parking lot of Longfor 1st Avenue has a distribution capacity of only 80kVA, including 150 sets of 3.5kW AC charging piles. Orderly charging scheme is adopted on site, and power distribution mode is flexibly adjusted to avoid on-site capacity expansion. The deployment scheme of cloud + end is adopted, and the orderly charging management and control terminal is used as the edge computing center, which realizes the localization of orderly charging control, and features faster response speed, lower networking cost and less network traffic.
