Problems solved by technology

During the peak period of residential electricity consumption, if the available load power of the charging station is less than the total rated power of all charging piles in the station, the number of available charging piles will decrease at this time, resulting in a low utilization rate of the charging station equipment
[0004] Moreover, some small-capacity charging stations will not be equipped with a monitoring and management system
When the on-board battery pack is nearly full, its charging demand power will be reduced to about one-fifth of the rated capacity of the battery. At this time, there will be more remaining capacity in the charging station. If it cannot be used effectively, it will also cause the charging station to fail. Low load utilization
[0005] The existing technology has the following problems: There are large differences between the original communication protocols of different charging pile manufacturers and the communication protocols of the monitoring and management system, which makes it very inconvenient and inflexible to connect the charging pile to the monitoring and management system; During the peak period of residential electricity consumption, if the available load power of the charging station is less than the total rated power of all charging piles in the station, the number of available charging piles will decrease at this time, resulting in a low utilization rate of the charging station equipment; , there will be a lot of remaining capacity in the charging station, if it cannot be effectively used, it will also cause the load utilization rate of the charging station to be low

Embodiment Construction

[0027] Below in conjunction with embodiment the present invention is further described.

[0028] Such as figure 1 As shown, the charging pile cluster controller has the function of communication protocol conversion, which can improve the convenience and flexibility of charging pile manufacturers and charging station monitoring and management systems. An adaptive power distribution network composed of charging pile cluster controllers and charging piles, when the maximum allowable power of the charging station P MAX lower than the total rated power P of the charging station N , it can ensure that the equipment utilization rate of the charging station is maintained at a high level.

[0029] Flow chart of adaptive power allocation of charging pile clusters, such as figure 2 shown. The rated power of each charging pile is P N i , then the total rated power of n charging pile clusters is P N =P N 1 +P N 2 +···+P N n . The output power of each charging pile is P O i...

Abstract

The invention provides an adaptive power distribution method for charging pile cluster control. The method comprises steps as follows: a charging pile cluster is connected with a charging station monitoring and management system through a charging pile cluster controller, and an adaptive power distribution network for a charging pile cluster controller is formed; whether total rated power of the charging pile cluster is higher than the maximum permissible power of a charging station is judged; capacity utilization of the charging station is kept at a higher level by proportional distribution of powder. According to the method, total load power of the charging station is dynamically adjusted in real time; the capacity utilization of the charging station can be increased, and part of charging piles are prevented from being out of service in the peak season of electricity utilization; the load utilization rate of the charging station can be increased, and surplus power when a battery packis almost fully charged can be effectively utilized.

Description

technical field [0001] The invention relates to a charging pile cluster control management technology, in particular to a charging pile cluster control adaptive power distribution method. Background technique [0002] At present, during the construction, operation and expansion of charging stations, various charging equipment from different charging pile manufacturers need to be connected to the monitoring and management system. Due to the large differences between the original communication protocols of different charging pile manufacturers and the communication protocols of the monitoring and management system, the work of connecting charging piles to the monitoring and management system becomes very inconvenient and lacks flexibility. [0003] At the same time, the rated electricity load in the area where the charging station is located is fixed. In principle, the residential electricity load should be satisfied first, and the remaining available capacity should be alloca...
