The utility model solves the technical scheme that its technical problem adopted: this parallel heavy-current direct current drive vehicle charging stake system; It is characterized in that; Comprise main control module; And the touch display screen, direct current energy accounting module, IC-card module for reading and writing, bill printing module, DC power supplier, electric automobile communication module and the charged in parallel module that electrically connect with main control module respectively, DC power supplier one end and AC380V electrically connect, and the other end and charged in parallel module electrically connect.
The charged in parallel module is formed for the multi-channel parallel charging inlet.
Every road charging inlet comprises charge switch, current detection module, charging socket and connection detection module; The positive pole of charging socket connects the positive pole of current detection module, the positive pole and the DC+ of charge switch successively; The negative pole that connects current detection module successively of charging socket, the negative pole and the DC-of charge switch are connected control line Ctrl behind the negative pole of connection detection module connection current detection module and the negative pole of charge switch.
Charge switch is be in parallel a plurality of, and current detection module is be in parallel a plurality of, and charging socket is be in parallel a plurality of, and connection detection module is be in parallel a plurality of.
DC power supplier is an IGBT high frequency direct-current switch power supply.
Main control module is programmable logic controller (PLC) PLC.
The charging method step of parallel heavy-current direct current drive vehicle charging stake system is following:
A) main control module obtains the charging requirement of electric automobile and the charge parameter of importing through touch display screen through the electric automobile communication module;
B) main control module detects the signal that is connected of every road charging inlet and electric automobile through connection detection module;
C) whether main control module meets the permissible value of charging inlet according to the charging current that is connected the every road of calculated signals charging inlet of charge parameter and charging inlet: as be not more than its permissible value; Then open charge switch; DC power supplier work; Begin charging, continue to detect the signal that is connected of every road charging inlet and electric automobile simultaneously, until the charging end; Otherwise the charge closing switch stops the output of DC power supplier, on touch display screen, shows fault message.
Compared with prior art; The beneficial effect that charging method had of the parallel heavy-current direct current drive vehicle charging stake system of the utility model is: this parallel heavy-current direct current drive vehicle charging stake system has fast, the security performance advantages of higher of charging rate; Its charging method adopts charged in parallel interfacing and charging inlet connection of intelligent judgment technology; Can select corresponding charging inlet and charging cable according to charge parameter; But multi-channel parallel uses during big electric current; Because of charging plug and the charging cable volume is big, weight causes greatly operating difficulties, the problem of time-consuming, effort has realized big electric current (more than the 500A) direct current quick charge technology when well having solved large current charge.
