Description

Technical Field

[0001] This utility model belongs to the field of charging pile technology and relates to a charging pile power distribution device. Background Technology

[0002] With the global energy structure transformation and increased environmental awareness, electric vehicles, as an important carrier of green travel, have seen a surge in demand for charging stations to meet their charging needs. Currently, there are two charging solutions: split-type charging stations and integrated charging stations. Split-type architectures separate the rectifier module from the charging terminal, enabling power pool sharing, suitable for high-power centralized charging scenarios. Integrated charging stations, on the other hand, generally adopt a "single-pile, dual-gun" hardware configuration, integrating rectification, control, and billing functions into a single cabinet. When both guns operate simultaneously, the fixed power distribution mode cannot dynamically adjust the output according to the vehicle's battery status, and the power distribution of the charging station is not flexible enough, which not only reduces the utilization rate of charging facilities but also increases user waiting time.
