Group simultaneously stores；
Step 6: the detection module can detect the voltage, electric current and power of charging circuit described in the charging unit, pass through
The physical quantity that the signal transmission module will test is transmitted to the CPU module, and the CPU module will
The analog signal received is passed through after filter amplifying processing, analog signal is transmitted to the display screen carries out output and show；
Step 7: the detection module incudes the charge condition of the battery pack by the power transmission module, and will test
Signal be transmitted to the CPU module, and be transmitted to after analog-to-digital conversion, filter and amplification and digital-to-analogue conversion described
Display screen is shown that obtained physical quantity is transmitted to the mobile terminal by wireless network by the server；
Step 8: the information that the server carrys out information transfer module transmitting is compared analysis, sees whether charge
Failure: continue to charge if charging is normal, if charge fault occurs, enter step 9；
Step 9: the server, which is pulled up a horse, disconnects the connection of the emitter Yu the alternating current, and the alarm is rung, and notifies work
Make personnel and carry out maintenance and inspection, after repairing normally, continues to charge；
Step 10: whether the detection module is completed by the detections such as voltage, electric current charging: if not completing, continuing to charge, if filling
Electricity is completed, and the communication module can send information notice charging to the mobile terminal and be completed, and deduct fees automatically, the service
It is electrically disconnected that device can control the city, terminates charging.
