Power capacity distribution system for charging piles and control method therefor

Abstract

The invention discloses a power capacity distribution system for charging piles and a control method therefor, wherein the system includes: a plurality of charging piles, each of the plurality of charging piles being connected to a power supply; a user conventional load; a first current detection module for detecting a current of the user conventional load; a plurality of second current detection modules for correspondingly detecting a work current of each charging pile; and a distribution center module which performs the power capacity distribution on the charging piles which bring forward power capacity increasing applications according to a difference power supply capacity between an actual total power capacity of the power supply and a rated power supply capacity of the power supply, an actual power capacity of the user conventional load, and an actual power capacity of each charging pile when the actual total power capacity of the power supply is less than the rated power capacity. The system can perform reasonable distribution on the power capacity of each charging pile in the limited power supply capacity, alleviates the bottleneck problem of the power supply capacity, improves the efficiency, and promotes the user experience.

Description

technical field [0001] The invention relates to the technical field of power supply and distribution, in particular to a charging pile electric capacity distribution system and a control method thereof. Background technique [0002] At present, new energy vehicles, especially pure electric vehicles, are popularized rapidly, and large-scale charging pile construction, especially when building piles in old communities, has a very tight power supply capacity. [0003] For example, when the more traditional power supply and distribution method is used to supply power to the charging pile under the main air switch of the community or the main air switch of the corridor, an air switch with a certain capacity is installed on a charging pile, and it can be used within the range of its rated capacity. Electricity, the air switch will not trip, but in the peak period of electricity consumption, once the electric vehicle starts to charge, it is easy to cause the main air switch to trip...

AI Technical Summary

Problems solved by technology

[0006] Therefore, the first purpose of the present invention is to propose a system for distributing the electric capacity of charging piles, which can reasonably allocate the electric capacity of each charging pile under the limited power supply capacity, and solve the problem to a certain extent. Solved the problem of building charging piles, alleviated the bottleneck problem of power supply capacity, improved efficiency, and improved user experience
