It's about to fill up
But the battery is stuck at 98%.
Or half full charge
The phone suddenly shows "charging interruption".
Occasionally, there is a "lock gun" situation
You may have encountered the above problems
Indeed, the car as one of the necessary tools for travel, the stable way of replenishment is the foundation and the key "jump gun", "charging interruption" and other conditions will directly affect the use of electric vehicles, but what is the reason for the "jump gun"?
Today Xiaojie will take you to face the "truth"
SOC factory protection
SOC, the full name of State of Charge, that is, the charging state of the battery, also known as the remaining power, represents the ratio of the remaining discharge power and the fully charged power after the battery is used for a period of time or a long time, usually expressed as a percentage.
When the battery is fully charged, the internal chemical activity is high, and long-term storage may increase the safety risks such as self-discharge, overheating and even thermal runaway of the battery. Especially in the transportation and storage process, the vehicle may encounter various environments and conditions, and the non-full charge state can reduce safety risks. At the same time, long-term full charge will accelerate battery aging, affecting the cycle life and performance of the battery. Maintaining a certain amount of remaining power at the factory, such as SOC at about 50%, can make the battery in a relatively stable state in the storage and transportation stage, which is conducive to protecting the health of the battery.
In the process of charging, the situation of "jumping gun" and "charging dissatisfaction" that we often say is actually a normal phenomenon. The main reason for this is security. When the vehicle is overcharged, and the built-in BMS (battery management system) of the vehicle cannot automatically terminate the charging operation, it is likely to cause a short circuit of the battery, which will lead to a fire, resulting in unnecessary safety accidents. Such a setting can effectively avoid such hidden dangers and ensure the safety of vehicle charging. This is also one of the reasons why many careful owners find that even if the vehicle charging limit is set to 100%, the electricity can not reach 100%.
Pursuit full? This can be achieved by slow charging
If you are obsessed with the pursuit of 100% full power, it can be operated like this: After setting the SOC at the end of the car to 100%, charge the fast charging pile first, charge to the SOC threshold, and then switch to the slow charging pile for trickle recharge, so that you can achieve a true sense of "full". However, Xiaojie here warm tips, follow the rule of shallow charging and shallow discharge, more conducive to the lithium cell to maintain normal use, the car's battery health will be better.

Insulator failure
At present, Xiaojie charging adopts the national standard charging standard in China. Therefore, once the insulator detection failure occurs, we must first confirm whether the model and the interface meet the national standard requirements. At the same time, carefully check the vehicle charging port to see if there are foreign objects or water stains to avoid affecting the charging due to these factors. If the problem still cannot be solved after the above investigation, it is recommended to replace the charging pile and try charging. If the pile can not be charged normally, you can contact customer service staff for further help.
BMS- Overvoltage/alarm, timeout
To ensure that the charging process goes smoothly, please follow the following steps: First, confirm that the vehicle has stopped and turned off, then select the correct vehicle type (such as small cars such as passenger cars or large vehicles such as buses and heavy trucks) on the charging pile screen, and then follow the correct charging steps. If the charging pile display is abnormal, it is recommended to restart the vehicle or replace the charging pile and try again. If the vehicle electricity is too low, especially less than 10%, it is recommended to use AC charging pile for proper recharge, and then use DC charging pile for charging. If the problem persists, please contact customer service for help.
So what to do about it? Don't look down
When you encounter the situation of charging the jump gun, you can first try to re-insert the gun to see if you can return to normal charging. If you still jump the gun after re-inserting the gun, you can consider replacing the charging pile. If the vehicle still cannot start charging after replacing the charging pile, it is recommended that the owner contact the customer service staff in time to understand the relevant information about other available charging piles nearby. In addition, if there is a frequent jump gun problem, be sure to contact the after-sales service of the charging pile and the vehicle for professional testing. This can effectively avoid safety accidents during use and ensure that the charging process is safe and reliable.
