The invention has the beneficial effects as follows: make to prevent automotive discharge when electric motor car is in charged state, it is achieved discharge and recharge is mutual
Lock, to ensure personal safety.
Accompanying drawing explanation
Fig. 1 is the circuit theory diagrams of pure electric vehicle DC charging interlocking control circuit of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is further described.
Interlock switch loop provided by the present invention includes charging gun, charging socket, discharge loop and is serially connected with electric discharge and connects
The control of discharge branch road of tentaculum coil, with the connection of charging socket, charged state detection branch confirms that end is connected, charged state is examined
Surveying in branch road and be serially connected with auxiliary relay coil, the normally-closed contact of auxiliary relay is serially connected on control of discharge branch road, and electric discharge connects
The normally opened contact of tentaculum is serially connected in discharge loop.Whether it is in charged state by charged state detection branch detection vehicle, if
Being in, then the conducting of this charged state detection branch, the auxiliary relay coil being i.e. serially connected on this branch road obtains electric, makes to be serially connected in and puts
Normally-closed contact on electric control branch road disconnects, so that the electric discharge contactor coil dead electricity in control of discharge branch road, then discharges back
The normally opened contact of the electric discharge catalyst in road is in normally open, and now, discharge loop is off, so that electronic
Car prevents automotive discharge when being in charged state, it is achieved discharge and recharge interlocks, to ensure personal safety.
Physical circuit in the present embodiment as it is shown in figure 1, include charging gun 1, charging socket 2, by divider resistance 3, power supply 4
With testing circuit 5 constitute charged state detection branch, charge circuit, discharge loop, be serially connected with charging contactor coil 9 charging
Controlling brancher and be serially connected with the control of discharge branch road of electric discharge contactor coil 10, divider resistance 3 and power supply 4 and charging socket 2
CC2 is connected, and the CC2 of charging socket is connected with testing circuit 5, the outfan of testing circuit 5 and auxiliary relay coil 11, auxiliary
The normally-closed contact of relay is serially connected in control of discharge branch road, and control of discharge props up route electric discharge catalyst control signal, auxiliary continues
The normally-closed contact of electrical equipment and electric discharge contactor coil 10 are in series, in the normally opened contact concatenation discharge loop of electric discharge catalyst,
Discharge loop is made up of battery 7 and drive system, and charging controlling brancher includes charging contactor coil 9, charging contactor coil 9
One end is connected with BMS negative control end, and the other end is connected with the A+ end of charging gun by charging socket 2, and what i.e. charging contactor touched touches
The A+ signal that point is plugged in rifle 1 by battery management system 8 (bearing) and charging controls, and the normally opened contact of charging contactor is serially connected in and charges back
Lu Zhong, battery 7 connects and composes charge circuit with DC+ and DC-of charging socket 2, and battery management system 8 plugs in rifle 1 He by charging
Charging socket 2 is connected with A+, A-, S+, S-, PE of charger, carries out information transmission.
When the plug in rifle 1 of charging is connected with charging socket 2, the CC2 end of the resistance access charging socket 2 of rifle 1, detection are inserted in charging
With power supply 4, circuit 5 judges that charging inserts whether rifle 1 is connected with charging socket 2 by detection divider resistance 3, as reliable in connected, battery
Management system 8 detects and makes BMS negative control signal effective after battery 7 is in chargeable state, and A+ gives charge contact by charging socket 2
Device 9 is powered, charging contactor 9 adhesive, and testing circuit 5 will detect 6V voltage signal simultaneously, export flash by testing circuit 5
Driving signal to auxiliary relay 11, after auxiliary relay 11 coil electricity, normally-closed contact disconnects.If now electric discharge catalyst 10
Being in attracting state, after auxiliary relay 11 normally-closed contact disconnects, electric discharge catalyst 10 disconnects, if electric discharge catalyst 10 is in
Off-state, even if electric discharge catalyst control signal is effective, electric discharge catalyst 10 also will not adhesive, thus realize at Vehicular charging
Automotive discharge is avoided, it is achieved that the interlocking of discharge and recharge under state.
