Embodiment Construction

[0045] A detailed description will be given below in conjunction with the accompanying drawings.

[0046] refer to figure 1 , this figure is a schematic diagram of an embodiment of a DC fast charging pile according to the present invention, the charging pile includes: a pile body controller 1 and a plurality of power supply modules 2, each power supply module 2 is respectively connected to the pile body controller, The pile controller is a multi-unit power module controller. The multi-unit power module controller evaluates the power conversion efficiency of each power module by determining the aging degree of each power module, and then distributes the output of the power module according to the power conversion efficiency, so that each power module can work at the highest Conversion efficiency points save energy.

[0047] The control method of the multi-unit power module controller will be described below. refer to figure 2 , which is a schematic flow diagram of an embod...

Abstract

The invention discloses a multi-unit power supply module control method. The multi-unit power supply module control method comprises the steps of S1, determining the aging degree value of each power supply module according to the working current, the working temperature and the working humidity of each power supply module; S2, determining the conversion efficiency of each power supply module according to the aging degree value of each power supply module; and S3, determining the number of the power supply modules which need to be used according to the conversion efficiency of each power moduleand the total power of external demands, and controlling the power supply modules to output electric energy one by one. In addition, the invention further discloses a controller and a direct-currentrapid charging pile. By the adoption of the method, the accuracy of evaluating the aging degree of the power supply module is improved.

Description

technical field [0001] The invention belongs to the technical field of power supplies, and in particular relates to a multi-unit power supply module control method, a controller and a DC fast charging pile. Background technique [0002] In recent years, with the promotion and use of DC fast charging equipment, there are more and more application environments for DC fast charging equipment. However, in different application environments, there are also problems with the aging rate of power modules and unbalanced aging verification, and , because the current domestic charging piles are used in parallel with multiple power modules, therefore, with the increase in the power of DC fast charging piles, the number of modules used is also increasing. However, due to the single control method, the problem of unbalanced aging of the power modules of each unit is more serious, which increases the operating cost of the DC fast charging equipment. [0003] For aging, usually more attent...
