Abstract

The invention relates to an automatic control method for a power supply system of a DC charging pile, which comprises the steps that an AC contactor control coil KM1 is controlled by a switch JCQ1 of a contactor JC and an emergency stop button SE; when the emergency stop button SE and the control switch JCQ1 are switched on simultaneously, the AC contactor control coil KM1 operates, and the AC contactor JC is switched on, thereby realizing charging of a main circuit for a DC charging module; and when any one of the emergency stop button SE and the control switch JCQ1 is switched off, the AC contactor control coil KM1 controls the AC contactor JC to be switched off, and charging for the DC charging module is stopped. According to the invention, automatic charging control for the DC charging module is realized through the emergency stop button SE and the switch JCQ1, a circumstance that an original charging module cannot disconnect the main circuit in an emergency condition or when charging is completed is solved, and the stability and the safety of the power supply system are improved.

Description

A kind of electric power system autocontrol method for direct-current charging post
Technical field
The present invention relates to direct-current charging post technical field, be specifically related to a kind of electric power system autocontrol method for direct-current charging post.
Background technology
Greatly developing and using of electric automobile will become following trend, and its major reason applied of current obstruction is the construction of charging pile.Reason is also had to be exactly charging interval of electric automobile.Charging pile divides two kinds, and one is alternating-current charging pile, and one is direct-current charging post.Alternating-current charging pile is that the alternating current exporting 220V charges a battery through Vehicular charger.Direct-current charging post can export DC400V big current directly to charge in batteries.The direct-current charging post charging interval is than alternating-current charging pile charging interval much shorter.Therefore, direct-current charging post obtains the welcome of many clients.High-voltage great-current because direct current fills that stake exports in addition, very large to the device loss controlling main circuit, often there will be the situation that main circuit controls contact sintering; in case of emergency or after charging complete; break not open the situation of main circuit, this can damage electromobile battery, and there will be danger.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of electric power system autocontrol method for direct-current charging post, solve original charging module in emergency circumstances or after charging complete, break not open main circuit situation occur, improve stability and the fail safe of electric power system.
For achieving the above object, present invention employs following technical scheme:
A kind of electric power system autocontrol method for direct-current charging post, control system is adopted to control charging pile, the three-phase kilowatt-hour meter for detecting electric energy power and the DC charging module for powering to charging pile is comprised described in described control system, the end of incoming cables of described three-phase kilowatt-hour meter is connected with triple line A, B, C by contactor JC, and the leading-out terminal of described three-phase kilowatt-hour meter is connected with the end of incoming cables of DC charging module; The A line of described triple line is connected with triple line N line with the switch JCQ1 of contactor JC by switch S E successively, and the control coil KM1 of described contactor JC is connected on the wire between contactless contactor JCQ1 and triple line N line; Described three-phase kilowatt-hour meter is used for carrying out electric energy metrical in the charging process of DC charging module;
A kind of electric power system autocontrol method for direct-current charging post specifically comprises the following steps: A.C. contactor control coil KM1 controls by the switch JCQ1 of contactor JC and scram button SE; When scram button SE and control switch JCQ1 is simultaneously closed, A.C. contactor control coil KMI action, A.C. contactor JC closes, and realizes main line and charges to DC charging module; When in emergency stop switch SE and control switch JCQ1, any one disconnects, A.C. contactor control coil KMI controls A.C. contactor JC and disconnects, and DC charging module stops charging.
The invention has the beneficial effects as follows: the electric power system autocontrol method for direct-current charging post of the present invention, the charging controller to DC charging module is realized by scram button and wiring board control switch, solve original charging module in emergency circumstances or after charging complete, break not open main circuit situation occur, improve stability and the fail safe of electric power system.
Accompanying drawing explanation
Fig. 1 is system diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of electric power system for direct-current charging post, comprise the three-phase kilowatt-hour meter 1 for detecting electric energy power and the DC charging module 2 for powering to charging pile, the end of incoming cables of described three-phase kilowatt-hour meter 1 is connected with triple line A, B, C by contactor JC, and the leading-out terminal of described three-phase kilowatt-hour meter 1 is connected with the end of incoming cables of DC charging module 2; The A line of described triple line is connected with triple line N line with the switch JCQ1 of contactor JC by switch S E successively, and the control coil KM1 of described contactor JC is connected on the wire between contactless contactor JCQ1 and triple line N line; Described three-phase kilowatt-hour meter 1 is for carrying out electric energy metrical in the charging process to DC charging module 2.
A kind of electric power system autocontrol method for direct-current charging post: A.C. contactor control coil KM1 controls by the switch JCQ1 of contactor JC and scram button SE.When scram button SE and control switch JCQ1 is simultaneously closed, A.C. contactor control coil KMI action, A.C. contactor JC closes, and realizes main line and charges to DC charging module; When in emergency stop switch SE and control switch JCQ1, any one disconnects, A.C. contactor control coil KMI controls A.C. contactor JC and disconnects, and DC charging module 2 stops charging.
The present invention is by the charging controller of switch JCQ1 realization to DC charging module of scram button SE and contactor JC, solve original charging module in emergency circumstances or after charging complete, break not open main circuit situation occur, improve stability and the fail safe of electric power system.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection range that claims of the present invention determines.
