Abstract

The invention discloses an electric automobile multi-port direct current charging point which comprises a central control unit, a chargeable unit, a card swiping unit, an energy dispatching unit, a man-machine interface unit, communication units, a charging interface and a guidance control unit. The central control unit is respectively connected with the chargeable unit, the card swiping unit, the energy dispatching unit, the man-machine interface unit, the charging interface and the guidance control unit; the guidance control unit is connected with the charging interface; and the central control unit and the charging interface are respectively provided with the communication units for communicating with a charger. The direct current charging point can be multipurpose by calculation of the energy dispatching unit and the control of the central control unit, energy usage rate is increased, and the resource problem of large occupied area of a plurality of charging points is solved. Moreover, the multi-port direct current charging point can be managed and dispatched by a superior monitoring system, charging output power can be adjusted under the condition of power network load peak, and the influence on a power network is decreased.

Description

technical field [0001] The invention belongs to the technical field of chargers, and in particular relates to a multi-port DC charging pile for electric vehicles and a control method thereof. Background technique [0002] With the increasingly severe energy crisis and environmental crisis, electric vehicles have become the focus of current development. However, the popularity of electric vehicles has put forward higher requirements for the construction of charging facilities and efficient and convenient charging. Moreover, when charging electric vehicles, the area occupied by the construction of charging facilities is also a problem that cannot be ignored. In this situation of tight land resources, how to solve the problem of charging facilities and land resource allocation remains to be studied. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a multi-port DC charging pile for an electric vehicle and a contro...
