Intelligent charging station of electric automobile

Abstract

The invention discloses an intelligent charging station of an electric automobile, which comprises a charging machine and a charging terminal, wherein the charging machine comprises an alternating current power distribution module, a rectifying module, a switch matrix and a power controller; the alternating current power distribution module supplies power for the charging machine; each charging machine comprises a plurality of rectifying modules; the rectifying modules are divided into the groups of power units; the groups of power units are controlled and connected to the direct current output loops through the switch matrix; each direct current output loop is correspondingly connected with the charging terminal; the switch matrix switches each set of power units in the direct current output loops according to a control instruction of the power controller. The intelligent charging station can achieve the reasonable distribution of the distribution capacity of the power grid and ensurethe orderly power supply of residential areas and charging stations.

Description

technical field [0001] The invention relates to electric power engineering technology, in particular to a DC charging station for electric vehicles. Background technique [0002] With the rapid development of electric vehicles, the number of people using electric vehicles is increasing year by year, and the charging needs of users are very urgent. However, in the planning and design of the original distribution substation, the electric vehicle charging facilities were not included in the design capacity of the distribution substation. The existing distribution capacity of the distribution substation cannot meet the rapidly growing charging demand of the electric vehicle charging facilities. In addition, it is difficult to requisition land for the construction of charging facilities at present. In order to take into account the regional power distribution capacity and charging demand, the construction of electric vehicle charging stations based on the integration of transform...

AI Technical Summary

Problems solved by technology

[0003] At present, the conventional smart charging stations for electric vehicles have a single charging strategy, which cannot meet the charging needs in different scenarios.

In addition, during the charging process, the charging terminal often cannot effectively protect against some situations that endanger the charging safety.
