First, make sure that the charging cable is connected to the bit. Sometimes because the charging cable of the charging cable is very thick, the weight is heavy. Some people with less strength will have more difficulty lifting the charging gun.
It will cause the connection to be not in place and not plugged in tightly. As a result, the charging pile cannot recognize the connection. Secondly, some charging piles do not enter the charging state immediately after being plugged in, and the electric gun is in a state of self-protection and will be powered off.
If you encounter this problem, try to change the charging pile. The second is to find out from the problem of the vehicle itself, there are many factors that cause this problem, some are because of interference problems, some are because of the shutdown instructions sent by the on-board BMS, some are caused by the failure of the charger, or the communication between the charger and the battery does not match, or it is possible that the battery temperature is too high during charging, or the charging interruption caused by the temperature of the charging pile is too high.

If the cause of the battery is ruled out, this fault may be caused by the virtual soldering of components inside the charger, or poor performance.
There is a voltage comparison circuit inside the charger, which can monitor the real-time voltage of the battery and compare it with the output voltage of the charger to prevent the battery from overcharging and protect the battery.
When the charger is in use, components such as power tubes generate large amounts of heat, resulting in an increase in the temperature of the charger. In this case, if the components in the voltage comparison circuit are soldered, the pins of the components will be separated from the pads of the motherboard, forming a broken circuit; In addition, if the chip performs poorly, it can also become unstable due to temperature increases, which can lead to monitoring failures or false alarms.

There are a number of reasons for this problem:1. There is a problem with the battery of a new energy vehicle.
2.The battery cannot be charged because the temperature is too low. 3.
There is a problem with the connector of the charging cable. 4.The charging mechanism used is faulty, the charging pile is damaged, or the power supply is faulty.
What is a new energy vehicle.
There are five types of new energy vehicles, the first is a pure electric vehicle, the second is an extended-range electric vehicle, the third is a hybrid vehicle, the fourth is a fuel cell electric vehicle, and the fifth is a hydrogen engine Gaoque car. The type of battery used in electric vehicles is lithium iron phosphate batteries. Lead-acid batteries, ternary lithium batteries, lithium-ion batteries, and more.
How to distinguish new energy vehicles.
The license plates used by new energy vehicles and ordinary fuel vehicles are different. The license plates used by new energy vehicles are gradually greening for small cars and greening for large vehicles. Ordinary fuel vehicles, small vehicles use blue license plates, and large vehicles use yellow license plates.

<> if the new energy vehicle is always automatically disconnected during the charging process, then it may be that there is a problem with the vehicle's electrical equipment, or there is a problem with the charging pile, or the vehicle is interfered with during the charging process.
During the charging process of the car, if the voltage is unstable, or the grounding wire is not connected, the charging pile will automatically interrupt the charging when it detects this situation. In addition, if the battery temperature is too high during charging, or if the temperature of the charging pile is too high, the charging will also be interrupted to prevent dangerous accidents.
The following is a brief introduction to the reasons and solutions for the automatic power failure of the charging pile.
1. The charging load is too large.
We all know that it is dangerous once the charging pile is overloaded, so for the sake of Ansan or all, the charging pile will automatically enter the power-off mode as soon as it detects that the load is overloaded.
Solution: Generally, this situation is mostly caused by multiple vehicles charging at the same time in the same charging station, and then we can only choose to replace another charging station with fewer charging people.
The charging standards of charging piles in the peak period, flat period and trough period are different, and the charge will be a little higher during the peak period, so in order to help car owners save electricity bills, many APPs have automatic charging functions. As long as the plug is plugged in, the app will automatically charge at the right time.
Solution: If the automatic charging function is set on the APP, the charging pile will not be turned on when the time is not up, if the owner wants to start charging immediately, just cancel the function manually.
3. The charging port is not connected properly.
When charging, if the charging interface is not connected, then the vehicle will be interrupted from charging.
Solution: Check the charging port and reconnect it.
4. The charging socket is loose.
If you are using an old charging pile, you can remove the problem of loose charging sockets, and once the charging sockets are loose, it will lead to charging interruptions.
Solution: At this time, the charging pile needs to be replaced, if this problem occurs in the home charging pile, you should ask a professional maintenance electrician to check and repair.
The common key technologies of new energy vehicles mainly include vehicle integration technology, electric drive technology, energy storage technology, fuel cell technology, high-voltage electrical technology, etc. >>>More

All new energy electric vehicles with their own power supply on the car, the power supply is the electric energy stored in the battery, which can supply power to the DC motor through the controller, or convert the DC power into AC frequency conversion power through the inverter, and supply power to the AC motor, and the role of the AC motor or DC motor in the electric vehicle is the same.
To charge new energy vehicles and choose a charging method, we must first find out which charging mode the car supports and the appropriate charging location. >>>More
