As shown in the schematic circuit diagram of fig. 4, the connection method of the resistors in the charging guns 1 to 5 is different from that of a standard charging gun, and the connection method of the resistors in the charging guns 1 to 5 is specifically as follows: r4 is 2.7K omega, RC is 680 omega, wherein an S3 normally open switch is connected in parallel on R4, a 1.3K omega resistor is arranged in the charge and discharge control box 1-3, and a normally open relay is connected in parallel.

Under the conventional state: measuring the resistance values of CC and PE on a charging gun to be R4+ RC +1.3K omega =4680 omega;

and (3) discharging state: when the charging gun 1-5 is inserted into a vehicle, the vehicle enters a discharging waiting operation state after detecting that the resistance values of CC and PE are R4+ RC +1.3K omega =4680 omega, and after a discharging function is manually started on the vehicle, the vehicle starts to discharge to the charging and discharging control box 1-3, at the moment, the inside of the charging and discharging control box 1-3 is electrified, but current is not output to the second temperature control three-plug 3-1; when the discharging adapter 2 is installed on the first temperature-control three-plug 1-1, the probe contacts 1-13 are in contact with the telescopic metal probe 2-2, the resistance R21300 omega on the R2 circuit board 2-7 is recognized by the charging and discharging control box 1-3 after a loop is formed, the charging and discharging control box 1-3 outputs current to the second temperature-control three-plug 3-1 after recognition, and the first temperature-control three-plug 1-1 outputs current to the discharging adapter 2 to complete discharging operation;

It should be noted that:

1. in the discharging process, for example, when the discharging adapter 2 is loosened or detached, the charging and discharging control box 1-3 detects that the R2 resistor is disconnected, and immediately stops supplying power to the second temperature-controlled three-plug 3-1.

2. Under the charging and discharging state, the temperature rise of the temperature control resistor arranged in the temperature control three-plug and the discharging adapter 2 is monitored in real time, and the point contact charging and discharging work can be carried out when the charging and discharging temperature is abnormal.
