At the end of charging, the conducting of processing unit controlled motor reverse turn control circuit, motor reversion, charging gun unblock, charging gun can
Normal not charged extraction.By locking charging gun in charging process, it effectively prevent to pull out by mistake in charging gun charging process and fill
Electric rifle and cause the generation of phenomenon of arc discharge, it is ensured that charging personnel personal safety.
Further, by position detection unit detect motor whether lock into place, if motor-locking is in place, processing unit
Control disconnects motor and rotates forward control circuit, motor stalls, it is to avoid long-time stall damages the phenomenon of motor.
Brief description of the drawings
Fig. 1 is the structural representation of charging gun locking system.
Embodiment
The utility model is elaborated with specific embodiment below in conjunction with the accompanying drawings.
Structural representation for the charging gun locking system of pure electric coach is as shown in figure 1, the locking system includes electricity
Pond management system, electronic lock unit, the first relay a and the second relay b.Wherein, electronic lock unit is arranged on charging socket
On, including motor M and position switch.One end b1 of one end a1 of first relay a coil and the second relay b coil points
Not Lian Jie battery management system the first control end Pin1 and the second control end Pin2, the other end of the first relay a coil
The other end b2 of a2 and the second relay b coil is grounded.First relay a normally opened contact a5's and the second relay b
Normally opened contact b5 is connected with power supply respectively, and the first relay a normally-closed contact a3 and the second relay b normally-closed contact b3 are equal
Ground connection, the first relay a common port a4 is connected motor M two ends with the second relay b common port b4 respectively.Electronic lock list
One end of the position switch of member connects the 3rd control end Pin3 of battery management system, other end ground connection.
In above-mentioned locking system, motor is constituted by the first relay a and rotates forward control circuit, by the second relay b
Motor reversal control circuit is constituted, the controlled motor in charging is respectively used to and rotates forward to lock charging gun and in charging complete
Controlled motor reversion is to unlock charging gun afterwards, but motor rotates forward control circuit and motor reversal control circuit is not unique, in reality
In the case of existing above-mentioned functions, it would however also be possible to employ other control circuits provided in prior art.
Position switch constitutes position detection unit, and when charging gun lock into place, feedback is sent to battery management system
Signal, battery management system control disconnects motor and rotates forward control circuit, and motor stops rotating forward；When charging gun is unlocked in place
Afterwards, feedback signal no longer is sent to battery management system, battery management system control disconnects motor reversal control circuit, motor
Stopping is rotated backward, and effectively prevent because long-time stall causes motor damages.In the case where realizing identical function, position
Put switch also replaceable into other detection parts.Certainly, in the case where not considering whether motor damages, in the locking system
Position detection unit can be not provided with.
Whether battery management system is used to detecting whether charging gun inserts to charge starts and whether rechargeable battery is full of
Charge and whether terminate, if charging starts, control conducting motor rotates forward control circuit；If charging terminates, control conducting motor is anti-
Turn control circuit.In addition, battery management system can also disconnect motor and rotate forward according to motor-locking or unblock situation in place, control
Control circuit or motor reversal control circuit.In the case where realizing equal function, the battery management system can also use its elsewhere
Unit is managed to substitute.Certainly, whether the processing unit for substituting battery management system can not also possess detection charging in itself
The function of beginning and end, but the signal that charging starts and charging terminates can be received.
In addition, when the power supply of power supply machine rotating is off-board recharging power supply, battery management system then for charging pile or fills
The battery management system in power station, accordingly, motor rotates forward control circuit and motor reversal control circuit is also deployed in outside car；Work as confession
When the power supply of motor positive and inverse is vehicle power, battery management system is then vehicle mounted battery management system, and accordingly, motor is rotated forward
Control circuit and motor reversal control circuit are also disposed in the car.
The operation principle of above-mentioned charging gun locking system is as follows：
When Vehicular charging, charging gun insertion, battery management system is detected after charging gun insertion signal, battery management system
The Pin1 output high RSTs of system, the first relay a coil electricities, the first relay a normally opened contact a5 closures, the first relay
A normally opened contact a5 and common port a4 conducting, the motor M two ends of electronic lock unit lead to forward voltage, motor main story, charging
Rifle is lockable.After charging gun is locked to position, the position switch of electronic lock unit is connected, and the Pin3 of battery management system is detected
After feedback signal, Pin1 stops output, the first relay a coil blackout, the first relay a normally opened contact a5 and common port
A4 disconnects, and restPoses, and locking motor M stops operating, it is to avoid motor long-time stall damages motor.
At the end of Vehicular charging, the Pin2 output high RSTs of battery management system, the second relay b coil electricities, the
Two relay b normally opened contact b5 closures, the second relay b normally opened contact b5 and common port b4 conducting, electronic lock unit
Motor M two ends lead to backward voltage, and motor anti-pass, charging gun is unlocked.After unlocking in place, the position of electronic lock unit is opened
Shut-off is opened, and the Pin3 of battery management system detects feedback signal disappearance, and Pin2 stops output, and the second relay b coil breaks
Electricity, the second relay b normally opened contact b5 and common port b4 disconnect, restPose, motor stops operating, it is to avoid electricity
Motivation long-time stall damages motor.
The present embodiment is coordinated battery management system to be realized with electronic lock unit and filled by two relays and electronic lock unit
Charging gun automatic locking when electric, reduces part, realizes simply, reduces cost.
