How to prevent "jump gun" when charging new energy electric vehicles?

November 20, 2023

First, what new energy electric vehicle charging "jump gun"?

In popular terms, there is a sudden power failure in the process of charging

The new energy electric vehicle charging jump gun actually refers to the phenomenon that the charging process is suddenly interrupted due to overheating of the battery or other factors during the fast charging process of the tram. In this case, the charging gun of the electric vehicle suddenly pops out of the charging mouth of the vehicle, just like a "jump gun", resulting in the charging process cannot be completed. Generally, electric vehicle charging jump guns are used to protect the battery and vehicle from overheating and other potential risks. When the temperature is too high or other abnormal conditions occur, the charging system will automatically interrupt the charging process to protect the safety of the battery.


Second, why do new energy electric vehicles "jump gun" when charging?

1. SOC threshold setting for electric vehicles

Set the SOC threshold of the electric vehicle

When the SOC (commonly known as the amount of charge, also known as the remaining electricity) is about 95%-98%

In order to protect the charging safety, the charging pile will automatically jump gun.

In order to prevent overcharging of electric vehicles, most new energy owners will set the SOC of the vehicle below 100%, and when the charging power has reached the preset SOC value, it will stop charging, which causes the situation of jumping guns

4. Charging gun failure: The charging gun connector is damaged or the internal parts are faulty, resulting in the failure to insert or pull out the charging port normally.

5. Charging interface problem: The charging port is blocked by foreign bodies, dirty or deformed, resulting in the charging gun cannot be inserted or pulled out. Freezing or sticking: In a cold environment, the moisture around the charging port may freeze, or the lubricant between the charging port and the charging gun may condense, making insertion or removal difficult.

6, the charging system is incompatible: the standard between the charging gun and the charging port does not match, resulting in difficulties when inserting or pulling out.

The above are some common reasons for the phenomenon of "jumping gun" when charging new energy electric vehicles. In case of charging problems, it is recommended to contact professional maintenance personnel or charging facility providers for troubleshooting and handling.


Third, how to reduce the "jump gun" before charging new energy electric vehicles?

"Jump gun" refers to the phenomenon that the charger automatically stops charging when the electric vehicle is charging due to various reasons. If you want to reduce this, you can try the following:

1. Temperature management: Keep the battery and vehicle at a suitable temperature. Too much heat or too much cold can cause a "jump gun".

2. Regular inspection: Regularly check the status of electric vehicles and charging equipment, and maintain and clean on time.

3. Charging mode selection: Using the appropriate charging mode, such as slow charging mode, will be more stable, but it will take longer charging time.

4. Reduce the number of charges: try to make each charge reach more than 80% of the battery, reduce the number of frequent charges.

5. Power management: Ensure that the power supply of the charging device is stable to avoid problems caused by voltage fluctuations.

6. Use a local brand certified charging station: Such stations often have better equipment and services, and can provide a safer charging environment.
