Detailed description of the invention

The core of the present invention is to provide a kind of alternating-current charging pile test system, is used for the stability to charging pile and life-spanTest.

In order to make those skilled in the art be more fully understood that technical scheme, below in conjunction with accompanying drawing and concreteEmbodiment, the alternating-current charging pile of the application is tested system and is described in detail introduction.

As it is shown in figure 1, be the principle general diagram of alternating-current charging pile test system in the present invention.This system include master control borad 1,The assemblies such as charging connecting base 3, load unit 4, master control borad 1 is equivalent to the brain of whole system, plays the effect that operation controls.FillElectric connection socket 3 is plugged in charging gun 2, is normally connected with charging gun 2 with the connection procedure during device chargings such as simulated automotive.ChargingConnecting seat 3 and be connected to load unit 4, load unit 4 determines required voltage and current value, charging gun 2 and charging connecting base 3 electricityAfter connection, the voltage of charging gun 2, with on current load to load unit 4, measures actual voltage value and the electric current of load unit 4Value, thus whether the output detecting charging gun 2 reaches normal level, for detecting output function and the performance of charging gun 2.

Master control borad 1 includes the assemblies such as signal gathering unit 11, control unit of swiping the card 12 and power supply unit 13.Signals collecting listUnit 11 is connected to charging connecting base 3, judges that when charging gun 2 is with charging connecting base 3 grafting both are the most normally connected.Swipe the card controlUnit 12 processed is swiped the card when using the POS 5 analog subscriber process, is used for testing alternating-current charging pile and swipes the card response speed, includingSwipe the card distance, frequency response etc. of swiping the card.Control charging gun 2 by the POS 5 whether to be energized.Master control borad 1 is by power supply unit 13Power supply.Charging pile includes the POS 5 and charging gun 2, and the POS 5 is swiped the card operation by user, the signal of the POS 5 controlWhether charging gun 2 is energized.

Alternating-current charging pile provided by the present invention test system is for measuring stability and the service life of charging pile.MeasureWhether the actual voltage value of load unit 4 and current value, be in normal scope with the transmission voltage and electric current determining charging gun 2Within, detect output function and the performance of charging gun 2 in real time.Control unit of swiping the card 12 is for simulating the mistake of the on/off of realityJourney, owing to power supply can be impacted to the process connected by open circuit, therefore by analog power break-make, makes charging pile constantly connectBeing impacted, can simulate the operation scenario of reality, also can test its stability, by swiping the card, control unit 12 is continuousGround carries out electric connection, can test the service life of charging pile.In sum, the alternating-current charging pile test system of the present invention is passed throughThe operating process that simulation is actual, can test the service life of charging pile and stability.

On this basis, the signal gathering unit 11 of the present invention is connected to CP Yu the CC interface of charging connecting base 3, is used for adoptingCP Yu the CC signal of collection charging connecting base 3.CC signal, for connecting confirmation signal, represents and is connected confirmation with charging gun 2；CP signal isPotential energy signal, represents that load connects and confirms.

Further, the power supply unit 13 in the present invention is AC/DC unit, and AC/DC unit is connected to electrical network and powers.AC/DCUnit is AC-DC converter, is directly connected in electrical network, and hands over common alternating current to be converted to unidirectional current, for masterControl plate 1 is powered, and makes other assemblies of master control borad 1 normally to work.Certainly, except using AC/DC unit unit by alternating currentBe converted to unidirectional current, other mode also can be used to power, be the most directly powered by set of cells.

Further, load unit 4 is AC load, and AC load is simultaneously coupled to charging connecting base 3 and electrical network.LeadingBeing additionally provided with load control unit 14 on control plate 1, load control unit 14 is used for the electric current needed for regulating load unit 4 and voltageValue.The charge condition of the equipment of different model when simulating actual charging by load control unit 14.

Being additionally provided with display control unit 15 on master control borad 1, display control unit 15 realizes aobvious by touching display screen 6Show and control.Touching display screen 6 and show the data of detection to user, user controls parameters according to the regulation of corresponding interface and setsPut, other assembly is sent control instruction.

Alternating-current charging pile test system in the present invention also includes that safety switch 7, charging pile with alternating-current charging pile test areSystem is connected in electrical network by respective socket respectively, unexpected in order to prevent test process from occurring, alternating-current charging pile test systemAnd on the circuit that is connected with electrical network of charging pile, safety switch is set, can be selected for air switch.Charging pile is tested with alternating-current charging pileSystem is received in electrical network commonly through safety switch.

As in figure 2 it is shown, be the flow chart of charging measurement process.First by device power, by charging gun 2 and charging connecting base 3Grafting, detects CP, CC signal by signal gathering unit 11 the most normal, if otherwise display " connects abnormal ", by manuallyIntervene and repeat to connect charging gun 2 and charging connecting base 3；If it is carry out next step, set electric current needed for load unit 4 withMagnitude of voltage, arranges the frequency and number of times swiped the card.Above-mentioned numerical value is provided with rear starting device, proceeds by test.

Judge the actual voltage measured of load unit 4 with electric current, the response of CP signal the most normally, if the result is negative, display" curtage or CP abnormal signal ", and terminate test；If result is yes, it is judged that whether continuous working period is T=f*n (fFor frequency of swiping the card, n is number of times of swiping the card), if then terminating test, if the result is negative, then repeat back judge process, it is judged that negativeThe actual voltage measured of carrier unit 4 responds the most normal with electric current, CP signal.

Tester observes the test result of indices by touching display screen 6, and the product development for the later stage provides excellentChange reference.It is also with the auxiliary equipments such as environment storehouse, by improving the temperature of test environment and combining Arrhenius theory simultaneouslyShorten test period, and then improve the efficiency of test equipment, reduce construction cycle and the cost of test product.

Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.Multiple amendment to these embodiments will be apparent from for those skilled in the art, as defined hereinGeneral Principle, can realize without departing from the spirit or scope of the present invention in other embodiments.Therefore, thisThe bright the embodiments shown herein that is not intended to be limited to, and be to fit to and principles disclosed herein and features of novelty phaseThe widest consistent scope.
