US 2018/0001780 A1 · MATRIX-TYPE FLEXIBLE CHARGING PILE AND A CHARGING METHOD CAPABLE OF DYNAMICALLY ALLOCATING POWER

Abstract

A matrix-type flexible charging pile and a charging method capable of dynamically allocating power are disclosed in the present invention, and the method comprises the steps of: S1, connecting each charging terminal to a corresponding electric vehicle; S2, receiving a charging power demand of the electric vehicle and comparing the charging power demand; S3, calculating the number of charging modules required to be additionally allocated to the present DC-bus and delivering it to a matrix controller; and S4, allocating the required number of charging modules in a dynamic power region to the corresponding DC bus and switching the module communication line to a corresponding communication bus synchronously. The implementation of the charging method capable of dynamically allocating power can satisfy the electric vehicle charging demands for different energy storage capacities and different charging rates, as well as improve the conversion efficiency and the utilization rate of the charging device further.
