YG 762 Use Method and Maintenance Method

  • Use method

1. The receptacle installation mode is installed in front of the panel, and installed on the charging interface of the car body,

Tightening force shall be 6~8N. M, in the process of locking bolts, use cross diagonal lock, to ensure the receptacle black silicone sealant gasket uniform compression;

2. When the charging interface is not charged, plug the receptacle cover and keep the charging interface clean;

3. During the car washing process, prohibit the high-pressure water gun to directly charge at the charging interface;

4. It is forbidden to use sharp tools to pick the internal reed of the metal terminal;

5. To avoid arc pulling, live plugging is prohibited;

6. Charging current is controlled within the rated current, and it is recommended to control within 85%~90% of the rated current;

7. Before charging, make sure the car stops and stops (according to the requirements of the manufacturer) and check the inside of the vehicle inlet (black plastic cavity)

Whether the body and metal terminal holes) are transferred from foreign bodies, if there are foreign bodies to be cleaned, and then use the charging gun for pre-insertion, if the charging gun can be normally inserted (feel no more than 14 kg force), in addition, the charging interface needs to detect whether the water phenomenon, to ensure the normal plugging and no water before charging;

8. During the charging process, turn on the temperature sensing and detection function of the BMS DC vehicle inlet;

9. After charging, close the receptacle cover.


  • Maintenance method

1. When the charging gun is inserted and stuck, check whether there is any foreign body drilling in the receptacle hole, and if there is no foreign body after inspection Normal plug and pull, contact the manufacturer for processing;

2. When reporting the insulation fault, first ensure that the battery service switch is disconnected, and close the main gate of the car body circuit system when necessary; Check and check whether the receptacle is leaking. If there is water leakage, use the multimeter to detect the insulation resistance between the terminals (except between PE and CC1), the resistance value of 2000M Ω is normal, otherwise contact the manufacturer for treatment;

3. In case of abnormal charging connection, first make sure that the battery service switch is disconnected, and close the car body circuit system if necessary

For the total gate, detect the resistance value between PE and CC1, if the resistance value is 1000 + / -30 Ω is normal, otherwise contact Manufacturer processing;

4. Wipe and clean the charging interface with alcohol, especially the metal jack inside the receptacle.
