The invention relates to the field of electric vehicles, and provides a charging power scheduling method and device for a matrix type flexible charging pile. The charging power scheduling method of the matrix type flexible charging pile comprises the following steps: receiving a first charging power demand of a first charging terminal, counting N charging module groups in an idle state, and scheduling the N charging module groups according to the historical accumulated use duration of each charging module group in the N charging module groups under the condition that N is not 0. And receiving a second charging power demand of the first charging terminal, calculating a difference value between the second charging power demand and the first charging power demand, and re-scheduling when an absolute value of the difference value is greater than a first threshold value. By implementing the application, the charging modules in the system can be used in a balanced manner by combining a charging module scheduling strategy on the basis of full-flexible power distribution, so that the charging power requirements of different electric vehicles can be met, and the reliability of the system is further improved.
Description
technical field [0001] The application relates to the field of electric vehicles, and in particular, to a charging power scheduling method and device for a matrix flexible charging stack. Background technique [0002] With the continuous popularization of new energy electric vehicles, the number and types of electric vehicles are increasing, and the output power requirements of charging facilities are quite different. In order to meet the charging needs of various types of electric vehicles in the society, flexible charging stack technology came into being. The current flexible charging stack mainly performs power dispatching according to the power demand of electric vehicles or the load capacity of the power grid. [0003] However, in the case of a given allocation demand, if there are multiple groups of charging modules available for dispatch, it needs to be allocated more effectively and reasonably. The usual allocation strategy of idle modules (groups) is to allocate b...
