In recent years, with the popularization of new energy vehicles, we have gradually enjoyed many conveniences. As a new product in the forefront of the market, we are often troubled by the use problems that follow. Why did the charging post jump? Why doesn't it charge when it reaches 95%?
What happened to the "gun jumping" of electric vehicles? Today, I will answer this question for you. This question may be caused by many reasons, including but not limited to the following:
01
SOC is about 98% to protect charging safety
SOC, full name of State of Charge, is the charging state and remaining power of the battery, usually expressed in percentage. In order to prevent the vehicle from overcharging and ensure the safe use of the vehicle, we usually set the SOC of the vehicle below 100%. When the charging power has reached the preset SOC value, the charging will stop. That is, when the pile end detects that the remaining power of the vehicle has reached the set value, the charging operation will be automatically stopped.
In this way, "gun jumping" and "insufficient charging" will occur when charging new energy vehicles. This protection setting is to avoid possible battery short circuit problem that may occur when the vehicle is overcharged and the built-in BMS (charging management system) cannot automatically interrupt the charging operation, which may lead to fire New energy vehicle charging pile Cause unnecessary safety accidents.
02
Battery management system (BMS) error
If the BMS of the vehicle is wrong, the charging process may be terminated in advance. This error may be related to the vehicle software upgrade or the communication module between the charging piles.
03
Power supply problem of charging pile
If the power supply of the charging pile is insufficient or exceeds the power of the on-board charger, the charging may also be interrupted. For example, if the power of the charging pile exceeds the bearing range of the household circuit, the protection mechanism may be triggered, leading to the interruption of charging.
04
Ambient temperature effect
When the ambient temperature is too high, the charging gun may activate the thermal protection device to prevent the battery from overheating and safety risks. If the battery temperature is too high during charging, the system will automatically stop charging and the gun will jump.
05
Charging interface worn
Long term use or improper operation may cause serious wear of the charging interface, which may also be one of the reasons for charging gun jumping. Electric vehicle charging pile

How to solve the problem of charging pile gun jumping
1. Re select slow charging pile: if the residual power of the vehicle has reached the preset SOC when "gun jumping" occurs, it can be regarded as normal. When the power fails to reach the relevant value and the gun "jumps", you can reinsert the gun and start charging again. At the same time, some charging stations will further reduce the SOC setting in order to increase the safety of the charging process in the high temperature season. Please consult the charging station service provider for the specific setting range. If you are looking for 100% full charge, you can select the slow charge pile to make up the trickle charge after the fast charge pile has charged to the SOC threshold value, so that you can achieve "full charge" on the premise that the SOC at the vehicle end is set to 100%.
2. Check the status of the charging pile and the vehicle: In case of gun jumping, first check whether the charging pile works normally and whether the charging interface of the vehicle is damaged or worn. If conditions permit, try to replace the charging post or charging interface.
3. Avoid high temperature environment: Avoid charging in high temperature environment, so as not to touch the heating protection device and cause charging interruption.
4. Update software: If you suspect that the gun jumps due to BMS error, you can try to update the software of the vehicle, New energy vehicle maintenance To fix possible problems.
5. Follow charging specifications: correct use and maintenance of the charging pile is crucial to ensure the charging safety and efficiency of electric vehicles. It is recommended to follow the use rule of shallow charging and shallow discharging, which is more consistent with the normal use state of lithium battery cells.
