Abstract

The invention discloses a charging pile control system. The charging pile control system comprises a switching power supply, an intelligent mainboard, an alternating current contactor and a charging gun seat, wherein the intelligent mainboard is connected with the switching power supply; a control terminal and a detection terminal are arranged on the intelligent mainboard; the alternating currentcontactor is correspondingly connected with the control terminal and the detection terminal; the charging gun seat is connected with the alternating current contactor; the intelligent mainboard is used for controlling the charging gun seat to charge a vehicle when the alternating current contactor is controlled by the control terminal to be closed; the intelligent mainboard is also used for controlling the alternating current contactor to be disconnected by using the control terminal when the vehicle is charged and controlling the charging pile to be powered down when the detection terminal detects that the alternating current contactor is in a closed state. According to the charging pile control system, by controlling the charging pile to be powered down when detecting that the alternating current contactor occurs adhesion, a situation that a user gets an electric shock due to the adhesion of the alternating current contactor is avoided, and the charging safety and reliability of an electric vehicle are effectively guaranteed.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a charging pile control system. Background technique [0002] With people's emphasis on green travel, electric vehicles are becoming more and more popular. In order to facilitate the timely charging of electric vehicles and ensure the normal operation of electric vehicles, there are more and more applications of charging equipment, and more and more charging piles are installed on the roadside. In order to charge electric vehicles, safety and reliability of charging equipment are very important when charging electric vehicles. When charging an electric vehicle, the AC current of the charging pile power supply passes through the AC contactor to charge the car. After the charging is completed, the AC contactor is disconnected to return to the original idle state; Leading to the charging gun head or the charging gun seat can easily cause electric shock and endanger safety. Conten...
