Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

As Figure 1-3, intelligent electric motor car charging device of the present utility model comprises relay, pre-paying kilowatt-hour meter 1, remote controller 2, the receiver module 3 corresponding with described remote controller, single-chip microcomputer 4 summation current transformer 5 and socket 6, described socket is in order to charge directly to electric motor car, it accesses civil power through after described current transformer 5 by power line after a pair normally opened contact and pre-paying kilowatt-hour meter 1 of relay 8, simultaneously, described single-chip microcomputer and described current sensor are kept in communication with receiver module and are connected, the coil of described relay is connected with described single-chip microcomputer is controlled.When single-chip microcomputer by current transformer sense power line circuit disconnect or too small time, automatically can cut off commercial power supply, stop electric motor car charging, until next time opens charging by remote controller again, effectively improve the fail safe of charging and the monopoly of use, prevent other people from usurping.Described remote controller and receiver module all can adopt existing commercially available chip.

The utility model adopts public charged area electricity charge household cost allocation, each household specifies respective socket, and by remote controller operation socket power on/off, each household arranges independent ammeter charging and ensure that use is fair, supply socket auto-breaking after electric motor car charging complete simultaneously, and pull up plug in charging process, panel auto-breaking, as needed energising, needs remote controller again to send electrical instruction, guarantee that I uses, be more that of avoiding electricity charge dispute.

Specifically, two output one termination signal grounds of described current transformer 5, the other end accesses the A/D sampling pin of single-chip microcomputer while transfer resistance R17 ground connection through rectifier diode D7, wherein, between rectifier diode and A/D sampling pin, signal ground is connect respectively through the filter capacitor C15 of parallel connection and voltage regulation resistance R18.Namely power line passes from AC current transformer 5, sensor current signal is converted to voltage signal through resistance R17, after carrying out halfwave rectifier and electric capacity C15 filtering and voltage regulation resistance R18 voltage stabilizing by diode D7 again, be connected to single-chip microcomputer and carry out A/D sampling, the magnitude of voltage that single-chip microcomputer monitoring current instrument transformer is sent, if this magnitude of voltage is less than preset value or is zero suddenly, illustrate that charging has been expired or user stops charging, relay power-off.This single-chip microcomputer also arranges the charging interval and is greater than 8 hours control relay power down function.

Preferably, the control signal of single-chip microcomputer is through divider resistance R19, resistance R20 and triode Q3 provides the electric current driving relay, specifically, the control signal that described single-chip microcomputer exports is communicated with the base stage of amplifying triode Q3 after divider resistance, the grounded emitter of described amplifying triode Q3, be connected with supply voltage VCC after the coil of the collector series relay of described amplifying triode, described coil is also parallel with discharge diode D9 and light-emitting diode D8, D8 as alternator indicator to point out power supply state, diode D9 effect is that when preventing relay power-off, induced current washes out amplifying triode Q3, discharge loop is provided.

Further, also comprise with described city's electric connection and provide the Transformer Rectifier module 7 of the not each electric device energy supply of supply voltage, it can adopt prior art, no longer launches to describe at this.

In specific implementation, described socket, pre-paying kilowatt-hour meter and other electric devices can directly be fixed on wall, user for ease of zone line charges, also comprise the hollow charging pile be fixedly connected with ground, described pre-paying kilowatt-hour meter is fixedly installed on charging pile top, the sidewall that described socket is fixedly installed on charging pile is arranged on bottom up and down accordingly with described pre-paying kilowatt-hour meter, other electric devices simultaneously, as receiver module, single-chip microcomputer, Transformer Rectifier module summation current transformer is fixedly installed in the cavity of charging pile, preferably, the cross section of described charging pile is regular polygon, as square or regular pentagon etc., each side arranges a set of pre-payment telegram and socket accordingly, user is more directly perceived, and decrease space duty, inner each electric device can be fixed on inside sidewalls, also can be carried by the dividing plate be fixedly connected with cavity, simultaneously, open the door to improve its usability in the side that charging pile is also provided with maintenance.

The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
