Description

Technical Field

[0001] The utility model relates to the technical field of charging stations, in particular to a charging system for centralized dispatching. Background Art

[0002] With the continuous improvement of economic level and the continuous advancement of science and technology, electric vehicles have developed rapidly. Electric vehicles refer to vehicles that use on-board power as power, use motors to drive wheels, and meet the requirements of road traffic and safety regulations. Because their impact on the environment is relatively smaller than that of traditional vehicles, their prospects are widely optimistic. As the number of electric vehicles gradually increases, the demand for charging piles is also increasing.

[0003] At present, there are the following problems with electric vehicle charging piles: 1) In many communities and parks, due to the limited capacity of the transformer, too many charging piles cannot be installed. If the number of charging piles is increased by force, the transformer may be overloaded, the power voltage may drop, the power quality may be affected, and even the power equipment may be damaged, resulting in power outages, which will have a serious impact on the power supply of the community and the park; 2) Some communities or parks may have already installed a certain number of charging piles in advance. As the number of electric vehicles increases, if the capacity of the transformer cannot be increased in time, a large number of charging piles may not be fully utilized, resulting in a waste of hardware resources; 3) For investors in charging piles, if more charging piles cannot be added due to the limitation of the transformer capacity, then their returns on investment in the layout of electric vehicle infrastructure will also be affected, which may lead to the problem of weakened motivation to invest in more charging piles. To solve this problem, it is necessary to increase the capacity of the transformer or improve the efficiency of the existing transformer. However, increasing the capacity of the transformer requires a large amount of capital investment and may require the expansion of power grid facilities, which is unrealistic for many communities and parks.
