Intelligent scheduling direct current charging pile group between dual gun piles and control method thereof

Abstract

The present invention discloses an intelligent scheduling direct current charging pile group between dual gun piles and a control method thereof, belonging to the electric car charging field. The group comprises three direct current charging piles with the same power specification, a power automatic distribution control cabinet and a high-voltage direct current cable; each direct current charging pile comprises a cabinet body, a control module, an alternating current 380V input, a three-phase miniature circuit breaker, a power module 1, a power module 2, a direct current charging gun 1, a direct current charging gun 2, a high-voltage direct current relay set AK-A, an AK-B and two cable interfaces; the power automatic distribution control cabinet comprises a power automatic distribution control module, a pile interface set and a nonpolarity high-voltage direct current relay matrix, the pile interface set comprises a pile interface 1, a pile interface 2, ..., a pile interface 6, and each pile interface is provided with corresponding interface of DC+ and DC-. The intelligent scheduling direct current charging pile group between dual gun piles and the control method thereof can satisfy the increasing power demand day by day, the design is reasonable, the integration efficiency is high, and the intelligence and the automation control can be realized.

Description

technical field [0001] The invention relates to the field of electric vehicle charging, in particular to an intelligently dispatched DC charging pile group between two gun piles and a control method thereof. Background technique [0002] In recent years, a large amount of energy has been consumed, and environmental pollution has become increasingly serious. Electric vehicles use electricity instead of fuel, which has the advantages of energy saving, environmental protection, low noise, light weight, and safety. Low-carbon, energy-saving, and safe electric vehicles are becoming more and more It is recognized by the majority of users. With the increasing popularity of electric vehicles, the problem of charging electric vehicles has become increasingly prominent. [0003] How to charge electric vehicles is an important issue. Charging piles can effectively solve the problem of difficult charging, and charging piles can quickly charge electric vehicles. The demand for chargi...
