Abstract

The invention provides a DC pile charging power flexible distribution system, which comprises a plurality of charging power module units, a plurality of charging guns, a plurality of switch switchingunits and a switch control unit, and is characterized in that the charging power module units are connected with the charging guns through the switch switching units, and the switch control unit is connected with the switch switching units; and the switch control unit flexibly controls the on-off state of the switch switching units according to the obtained power demand. The invention relates to aDC pile charging power flexible distribution method. The remaining power is borrowed and allocated when other charging guns are idle or need to be small, the load efficiency of the charging pile is improved, the load utilization rate of the charging station is increased, the bicycle charging time is shortened, and the unit time turnover rate of the charging station is increased.

Description

Technical field

[0001] The invention relates to the technical field of flexible distribution of DC pile charging power, in particular to a method and system for flexible distribution of DC pile charging power.Background technique

[0002] New energy electric vehicles are booming, and the demand for charging continues to increase. At this stage, the problem of too long charging time is widespread. There is an urgent need for many high-power charging piles, which are generally equipped with 2 to 4 charging guns. How to flexibly distribute the power of the charging pile to each charging gun. Many existing DC charging piles use a maximum fixed power for each gun. The remaining power cannot be seconded and allocated when other guns are idle or when the demand is small, resulting in waste of idle power , The load rate is low, and the cost performance is low.Summary of the invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a ...
