Problems solved by technology

The existing technical problems mainly have the following defects of insufficient capacity. There are two main reasons for this defect. One is that the budget, space, and transformer capacity are not enough; the other is that the old parking lot has insufficient space and the capacity of the transformer is not easy to expand.

Embodiment Construction

[0049] In the embodiment of the present invention, the running status of all the charging piles in the charging station is monitored in real time. If a certain charging pile starts charging, the total charging power of the charging piles that are already charging and charging is calculated. If the total charging power is adjusting the power Within the threshold, the rated power of the corresponding gun will be assigned to the charging pile that starts charging, otherwise, the charging power of all charging piles that are already charging will be pre-allocated to the charging piles that are already charging and charging, according to each charging pile The gun’s minimum power and the available total rated power are adjusted to output the pre-allocated power; if a charging pile stops charging, the charging power of the charging pile that stops charging is pre-allocated to the remaining charging piles that are charging, and according to each The rated power of the gun of the charg...

Abstract

The invention provides a power station power automatic control method and system. The method comprises the steps that S1 the operation state of charging piles is monitored in real time, if a charging pile starts charging, the step S2 is carried out, and if a charging pile stops charging, the step S3 is carried out; S2 the total charging power of charging piles which are in charging and start charging is calculated; if the total charging power is within a control power threshold, the rated power of the corresponding gun is allocated to the charging pile which starts charging and the step S1 is carried out, otherwise the charging power of all charging piles in charging is preallocated to charging piles which are in charging and start charging; according to the minimum power of the gun of each charging pile and the available total rated power, the pre-allocated power is adjusted and output, and the step S1 is carried out; and S3 the charging power of charging piles which stop charging is preallocated to other charging piles in charging; the preallocated power is adjusted and outputted according to the rated power of the guns of charging piles in charging; and the step S1 is carried out. According to the invention, the shortage of charging station resources can be alleviated.

Description

technical field [0001] The invention relates to the field of charging infrastructure, in particular to a method and system for automatic power regulation of a charging station. Background technique [0002] When charging, the transformer outputs power according to the input power of the charging pile. According to the total power and the power actually used, the available power is known, and then distributed to other charging piles. The existing technical problems mainly include the following defects of insufficient capacity. There are two main reasons for this defect. One is that the budget, space, and transformer capacity are not enough; the other is that the old parking lot has insufficient space and it is difficult to expand the transformer capacity. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic power regulation method and system for a charging station in view of the above-mentioned defects in ...
