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...
