Problems solved by technology
Although the control process of this method is simple, due to the inconsistency of the overall usage of the charging pile, it may cause a large load on one branch, while the utilization rate of another branch is not high.
This uneven utilization rate and load will cause problems such as performance degradation and shortened life of charging piles.

Embodiment Construction
[0022] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0023] refer to figure 1 , is a schematic diagram of the control flow of the first embodiment of the present invention. The present invention provides a control method based on charging pile balanced charging, comprising the following steps:
[0024] By accumulating and calculating the working conditions of each charging module respectively, and comparing the accumulated values, determining the charging module with the smallest value to perform the charging action;
[0025] Wherein, the working condition of the charging module includes start-stop time and / or start-stop frequency.
[0026] As an improvement of this technical solution, the working conditions of the charging modules represent the weighted sum calculation of the cumulative working time and cumulative working frequency of each charging module...

The invention discloses a control method and system based on charging pile equalizing charging. The method comprises following steps: performing accumulative calculating on work condition of each charging module and comparing the accumulative values to determine a charging module having the minimum accumulative value for charging; the work condition of the charging module comprises start and stop time and / or start and stop frequency. The invention also discloses a control system based on charging pile equalizing charging. According to the control method and system based on charging pile equalizing charging, through control and adjustment of work method of the charging modules, comparing work conditions of charging modules, a proper branch is selected to work so as to balance the work condition of charging modules and increase the system performance and service life of charging module. The method and system can be widely used in the field of charging piles.
Description
technical field [0001] The invention relates to the field of charging piles, in particular to a control method and system based on balanced charging of charging piles. Background technique [0002] With the gradual development of the new energy vehicle industry, the status of its supporting charging facilities - charging piles has increased in the industry. DC charging piles can provide high-power fast charging functions and have attracted widespread attention from the society. The working mode of its core component charging module is different due to the function of the product. [0003] For charging piles with two guns or multiple guns, the traditional way is to share the power equally, and the charging module operates according to the pre-grouped and corresponding branches. Although the control process of this method is simple, due to the inconsistency of the overall usage of the charging pile, it may cause a large load on one branch, while the utilization rate of anothe...
