Description
Technical field
The utility model relates to smart jack technical field, particularly relates to a kind of smart jack of automatic identification electric car charger.
Background technology
A kind of socket of save electricity that what smart jack was popular say; the theory of energy-saving socket just generated very early; what up to the present developed is more extensive; but the technical progress that needs: the high-grade energy-saving socket having not only economizes on electricity; can also protective device, say its protective device, be mainly to have from it the function of removing electric power rubbish; what have also adds anti-lightning strike, anti-short circuit, antioverloading, anti-creeping function, produces the functions such as electric pulse while eliminating Switching Power Supply goods electrical equipment.
Current electric motor car, taking the electric automobile of electric bicycle, electro-tricycle and low side as main, also has the high-end electric bus of part trial run, and the former is the result of society and nature's demand, and the latter is the result of policy support; These electric motor cars are substantially all the needs that meet short distance trip or transport, and charging work is all to be solved by user oneself substantially, very inconvenient, has been charged to a large difficult matter, thereby have caused random charging, random phenomenon of parking.
Have about the patent overcoming the above problems, comprise CN203102445U, CN203055001U, CN102044723B etc., all mention the Charge Management to electric motor car, but all do not relate to the self energy identification to electric motor car charging plug, the identification electric motor car charging plug that socket itself can be single-minded of justing think, only in the time that electric motor car charging plug inserts, smart jack is just powered, remaining electronic product inserts no current to be passed through, like this, just can well avoid disorderly charging and carry out private behavior with public power steathily, for this reason, the utility model has been researched and developed a kind of intelligent charge socket for electric motor car identification.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of smart jack of automatic identification electric car charger, effectively identifies the plug of electric motor car, repels other electric equipments, thus protection charging device.
The technical scheme that the utility model adopts is: a kind of smart jack of automatic identification electric car charger, comprise power supply voltage terminal L, power supply voltage terminal N and testing circuit, it is characterized in that testing circuit is made up of resistance R 6, K switch 1, diode D6, resistance R 13, photoelectrical coupler O2, resistance R 14, resistance R 6, K switch 1, diode D6 form ON-OFF control circuit, and in photoelectrical coupler O2, light-emitting diode is by resistance R 13 current limlitings;
In described photoelectrical coupler, O2 has a light-emitting diode and a phototriode, lumination of light emitting diode while having voltage to produce, and phototriode testing circuit has no current to pass through;
Described testing circuit do not have charger insert time, generation current in circuit, in photoelectrical coupler O2, light-emitting diode is not luminous, phototriode is without On current, node NET2 place voltage is 5V;
Described testing circuit is in the time having charger to insert, generation current in circuit, lumination of light emitting diode in photoelectrical coupler O2, photosensitive triode On current, node NET2 voltage <5V, node is by input information to Chip Microcomputer A/D port, and single-chip microcomputer detects that voltage changes and has been judged as electric car charger and inserts.
As preferably, the K switch 1 in described testing circuit is double-point double-throw switch.
Compared with prior art, the beneficial effects of the utility model are: the smart jack of automatically identifying electric car charger, stopping other equipment uses, such as: electric rice cooker, hair-dryer, electric furnace, these powerful devices of thermos all cannot use, battery of electric vehicle is full of automatic circuit break function, general charging system is timing, the utility model detects in real time, battery is full of stops power supply, effectively avoid overcharging and bring battery explosion, the faults such as components and parts heating is on fire, without relying on charger self configuration, if electric power exceedes electric motor car charge power, smart jack quits work.
Brief description of the drawings
Fig. 1 is the internal circuit diagram of this socket.
In figure, R is that resistance, K are that switch relay, D are photoelectrical coupler for protecting diode, O.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, a smart jack for automatic identification electric car charger, comprises L, N and testing circuit, and testing circuit is made up of R6, K1, D6, R13, O2, R14, wherein R6, K1, D6 form ON-OFF control circuit, and in O2, light-emitting diode is by R13 current limliting; The insertion of light-emitting diode induction electricity charger in O2 in described testing circuit, in O2, phototriode has On current; K1 in described testing circuit is double-point double-throw switch
Embodiment: while not having electric car charger to insert when O2 light-emitting diodes, do not have electric current to pass through, phototriode is without On current, NET2 node voltage is 5V, in the time having charger to insert, between charger L, N, has certain resistance, and in O2, light-emitting diodes is luminous, in O2, photosensitive three pipes have certain On current, NET2 node voltage is <5V, and NET2 is input to Chip Microcomputer A/D port, single-chip microcomputer detect voltage change be judged as charger insert.
Above-described embodiment; it is only several representative example of the present utility model; not be used for limiting enforcement of the present utility model and interest field, all or technical schemes of being equal to identical with content described in the utility model claim, all should be included in the utility model protection range.
