Detailed description of the invention
Charging electric vehicle as Figure 1-5 connects confirmation device, its structure is: the signal output part at governor circuit 1 is connected to display screen 2 and pwm signal output module 3, governor circuit signal output part is connected to control input 4, control input 4 includes each independent be connected with governor circuit 1 testing button 4-1, SR 4-2, manual/auto switching button 4-3, PWM control knob 4-4, dutycycle button 4-5 and frequency button 4-6; Being connected to charging indicator light 7 on vehicle charging socket 6, signal detection module 8 is connected on vehicle charging socket 6, pulse input detection signal, resistance input detection signal and alternating voltage detection signal is transferred in governor circuit 1.
Described governor circuit 1 is also associated with lithium battery group 9 and 220V power supply 10.
Described signal detection module 8 includes alternating current collecting part 8-1 and AD collecting part 8-2.
Time actually used, the working condition of electric automobile charging pile can be detected by this utility model, and detects fault Producing reason. This utility model in use has the effect of simulation electric automobile, the each parameter of electric automobile charging pile can be carried out real time scan, and then judge whether charging pile meets charging requirement, wherein, the parameter that detect has: CP frequency, CP dutycycle, power supply maximum current, RC resistance, cable capacity, input voltage value etc.
When electric automobile charging pile is connected with this device, firmly whether invention first determine whether to connect, i.e. detection RC resistance, when detecting that RC resistance and its value are in prescribed limit, now judges to be connected as being reliably connected; Meanwhile, according to RC resistance, it may be determined that the size of cable capacity; When RC resistance or RC resistance exception being detected, doing and go out alarm on a display screen, according to alarm, connecting portion can be checked or change by related personnel.
Under the premise that is connected firmly, CP frequency, CP dutycycle are detected by invention, to determine whether charging pile meets charging electric vehicle requirement, when CP frequency, CP dutycycle are in its prescribed limit, it may be determined that charging pile connection line is normal;Meanwhile, the numerical value according to CP frequency, CP dutycycle, it is possible to obtain the maximum supply current of charging pile, now judges whether charging pile cable capacity and its match; When CP frequency, CP dutycycle cannot be detected or its value beyond in prescribed limit, alarm can be made, according to alarm, connection line or charging pile can be detected or change by related personnel.
All above detected value is all in its prescribed limit, Guan Bi charging ACK button, now charging pile is in running order, now detect the input voltage of electric automobile charging pile, when the input voltage detected is in prescribed limit, test is passed through, and illustrates that the duty of charging pile is good, can be used for charging electric vehicle.
When alarm occurs, according to abnormal alarm data search relevant position, problem producing cause can be investigated rapidly.
