The voltage detection device 70 is used for detecting voltages of various devices inside the charging device 100, and in the present embodiment, the voltage detection device is a voltmeter. The network detection element 80 is configured to detect whether the network of the charging device 100 can be conducted, and in this embodiment, the network detection element 80 is an ethernet tester. The gun insertion detecting element 85 is disposed inside the charging gun 20, and is used for detecting and recording the number of times the charging gun 20 is inserted into the vehicle. The power-off element 90 is used to cut off the power supply connection of the charging device. In this embodiment, the power cutoff element 90 is a circuit breaker. The reminding element 95 is used for receiving the reminding instruction transmitted by the processor and sending out voice reminding. In this embodiment, the reminding element 95 is a voice prompter, and can send out voice information to inform the user of the state of the charging device 100 after receiving a reminding instruction.

In this embodiment, the processor 40 is a PX3-SE processor. After receiving the level signal detected by the pressing detection element 50, the processor 40 controls the stop electronic element to stop the power supply of the charging device 100 or detect the state of the charging device 100 according to the number of changes of the level signal, and generates a reminding message according to the detection result.

Further, when the received current does not match the preset current value, the processor 40 indicates that the current is abnormal. Further, if the received current is smaller than the preset current value, it is indicated that the charging device 100 has an undercurrent, a second reminding message is generated and sent to the reminding element 95, and the content of the second reminding message may be "charging device undercurrent"; if the received current is greater than the stored current value, it indicates that the charging device 100 is in a state of six, and generates a third reminding message to be sent to the reminding element 95, where the content of the third reminding message may be "charging device overcurrent".

Similarly, if the received voltage is smaller than the preset voltage value, fourth reminding information is generated, and the content of the fourth reminding information may be 'charging equipment under-voltage'; and if the received voltage is smaller than the stored voltage value, generating fifth reminding information, wherein the content of the fifth reminding information can be 'overvoltage of charging equipment'.

Similarly, if the received network delay is greater than the preset network delay, it indicates that the network of the charging device 100 is not available currently, at this time, the processor 40 generates a sixth reminding message and transmits the sixth reminding message to the reminding element 95, and the content of the sixth reminding message may be "network not available currently".

Further, when the processor 40 determines that the received current, voltage and network delay all match the stored values, the processor 40 generates a seventh alert message to be transmitted to the alert element 95, where the content of the seventh alert message may be "charging device current, voltage, network normal".

It can be understood that, if the processor 40 determines that at least two of the current, the voltage and the network delay are abnormal, the processor 40 correspondingly generates at least two pieces of reminding information to the reminding element 95, and the reminding element 95 broadcasts the at least two pieces of reminding information at the same time.

Further, when the emergency stop button 30 is pressed three times within a preset time, the pressing detection element 50 detects the level change three times and transmits the detected level change to the processor 40. The processor 40 controls the gun insertion detection element 85 to transmit the recorded plugging times of the charging gun 20, and the processor 40 compares the plugging times with preset times in the system after receiving the plugging times and generates reminding information according to a comparison result. Specifically, if the recorded number of times of plugging and unplugging is not greater than the preset number of times, the processor 40 generates eighth reminding information and transmits the eighth reminding information to the reminding element 95, and the content of the eighth reminding information may be "the charging gun exceeds the service life, please replace"; conversely, the prompting element 95 generates a ninth prompting message, and the content of the ninth prompting message may be "the charging gun does not exceed the service life, and does not need to be replaced".

Further, when the emergency stop button 30 is pressed four times within the preset time, the pressing detection element 50 detects four level changes and transmits the detected level changes to the processor 40. The processor 40 will restore the factory setting, and generate tenth prompting information, where the content of the tenth prompting information may be "the factory setting of the charging device is restored. It can be understood that the factory restoration setting is to restore each parameter and storage information of the charging device recorded in the processor to a default state at the time of factory shipment.
