Embodiment 1

[0058] For example, if the current redundant capacity is 100KW (P1), the maximum power of each charging pile is 4KW (P3), and after calculation, there are 25 charging piles that can be connected (C2=P1 / P3), and the actual current charging piles are 30. (C1), according to the ratio of C2 / C1, the actual number of charging piles that can be put into use is calculated as C3= (C2 / C1)×C2=(25 / 30)×25=20.8, and the integer is 20 charging piles ( C3), and put into charging according to the calculated priority.

[0059] After 10 minutes, recalculate the current redundant capacity of the transformer. When calculating, the actual power of the 20 charging piles is 60KW (G). The calculation of the number of charging piles or the power-off sequence is still carried out according to the above method. Assuming that the external load of the charging pile has not changed, recalculate the current redundant capacity of the transformer as P1=100-60=40KW, and calculate the number of charging piles th...

Embodiment 2

[0061] According to the capacity of the transformer, it is divided into equal intervals by 10. For example, if the capacity of the transformer is 50, each interval is 0-10, 10-20, 20-30, 30-40, 40-50. If the load within 15 days is as follows:

Abstract

A coordinated control method for intelligent charging of electric vehicles, which solves the technical problem that the existing intelligent charging management of electric vehicles does not realize economical and rational charging. Charging of electric vehicles. The basis of the present invention can be that one or more outputs of the transformer are connected to the charging pile separately, and the load monitoring is carried out separately with the external load of the charging pile, which better realizes the use of the redundant capacity of the transformer to support the normal power consumption. Intelligent charging management for electric vehicles. When balancing the redundant capacity of the transformer and the number of electric vehicle charging needs, determine the number of charging piles that can be put into each time according to the percentage, and put into charging according to the priority of the charging piles, instead of putting all the redundant capacity into the charging piles at once , reducing the negative impact of sudden increase in transformer load.

Description

technical field [0001] The invention relates to an electric vehicle charging management method in the field of energy management, in particular to a coordinated management method for electric vehicle intelligent charging applicable to public places such as supermarkets and shopping malls. Background technique [0002] Against the backdrop of increasingly tense environmental protection and traditional energy supply, the new energy automobile industry chain has become a new trend in the future development of the automobile industry. New energy vehicles and charging facilities complement each other, and the strong development momentum of new energy vehicles has increased the demand for charging facilities. The charging facilities market is about to explode, and the industry will also usher in an investment climax. According to the requirements of the current situation, the main construction locations of charging piles are mainly destinations, such as residential areas, shopping...
