When an electric vehicle charger has an unpleasant smell during use, it may indicate a safety hazard or equipment failure, and it needs to be dealt with promptly. The following are some processing steps and suggestions:
First, stop charging immediately
Once an unpleasant smell is detected in the charger, regardless of the intensity or source of the smell, charging should be stopped immediately. This is the first step to prevent potential dangers.
Second, determine the source of the unpleasant smell
The charger itself:
If the unpleasant smell comes from the charger, it might be caused by reasons such as poor soldering of internal components, overheating of the circuit or failure of the cooling system. At this point, it is necessary to carefully observe whether the charger shows any signs such as charring, deformation or smoking.
Charging interface:
If the unpleasant smell comes from the charging interface, it may be caused by poor contact of the interface, oxidation and blackening of the copper contacts, or melting of plastic components, etc. At this point, it is necessary to check whether the charging interface is loose, deformed or charred, etc.
Battery
In very rare cases, the unpleasant smell may come from the battery itself. If the battery gives off a pungent smell during the charging process, it might be a normal phenomenon of hydrogen release (although this situation is relatively rare, vigilance still needs to be maintained).
Third, deal with the odor based on its source
Charger problem:
Internal component false soldering: It is necessary to have professionals disassemble and solder the charger.
Overheating of the circuit or failure of the cooling system: You can try disassembling the charger and cleaning the dust and dirt on the cooling system (such as fans, heat sinks, etc.). If the problem persists, it may be necessary to replace the charger or seek professional repair.
Charging interface issue:
Poor contact: Check if the charging interface and charging cable are damaged or aged. If necessary, replace the charging interface or charging cable with new ones.
Copper contacts oxidized and turned black: Use sandpaper or a special cleaner to remove the oxide on the copper contacts to ensure good contact.
Battery problem:
If the unpleasant smell comes from the battery itself and is accompanied by abnormal phenomena such as smoke and heat, you should immediately move away from the vehicle and contact professional maintenance personnel for handling.
Fourth, preventive measures
Regular inspection and maintenance:
Regularly check the status of the charger and charging interface to ensure there is no damage or aging.
Regularly clean the cooling system of the charger to prevent the accumulation of dust and dirt, which may cause overheating.
Use the appropriate charger and charging cable:
Make sure that the selected charger and charging cable match the charging interface and voltage level of the vehicle.
Avoid using inferior or uncertified chargers and charging cables.
Comply with charging regulations:
During the charging process, abide by the local charging norms and electrical safety regulations.
Avoid charging in damp, dusty or flammable and explosive environments.
Charge in time
Form the habit of charging the battery on the same day it is used to avoid over-discharging or long-term undercharging of the battery.
Fifth, Precautions
Do not disassemble the charger by yourself.
If you are not a professional, please do not disassemble the charger by yourself. Improper disassembly may lead to equipment damage or safety accidents.
Avoid using wet hands or metal contact with the electrode:
During the charging process, avoid touching both ends of the electrode with wet hands or metal objects to prevent electric shock or short circuit.
Seek professional help
If you are unable to determine the source of the unpleasant smell or solve the problem by yourself, please contact a professional maintenance personnel immediately for handling.
