How to deal with the unpleasant smell problem of electric vehicle chargers

To deal with the odor problem of electric vehicle chargers, targeted measures should be taken in combination with the source of the odor, while paying attention to safe operation. The following are the specific methods:

First, identification and treatment of the source of unpleasant odors

Internal problem of the charger

The reason is that the internal circuit of the charger overheats, the components are poorly soldered or have poor contact, causing local heating and generating a burnt smell.

Treatment method:

Stop charging immediately to ensure safety.

Disassemble the charger by yourself, clean the cooling system, and check if there is any accumulation of dust or dirt that may affect the cooling effect.

If the unpleasant smell persists after cleaning, it might be due to poor soldering or poor contact of the internal components of the charger. It is necessary to seek professional maintenance personnel for soldering repair or component replacement.

Problem with the charging interface

Cause: Poor contact at the charging interface leads to high temperature, melting the surrounding plastic and generating a burnt smell.

Treatment method:

Check whether the charging interface is clean and free of foreign objects, and whether the copper contacts are oxidized and blackened.

If any problem with the interface is found, it is recommended to replace the charging interface or the charging port of the charger.

Battery problem

Reason: During the charging process of the battery, gases such as hydrogen may be produced. Although they are odorless under normal circumstances, battery malfunctions or aging may cause abnormal odors.

Treatment method:

If you suspect that the problem lies with the battery, stop charging immediately and contact a professional maintenance person for inspection.

Avoid using open flames or generating sparks during charging to prevent accidents.

Second, safe operation and preventive measures

Stop charging immediately: Once you notice an unpleasant smell from the charger, stop charging immediately to avoid potential safety risks.

Choose an appropriate charging environment: When charging, select a well-ventilated, dry and fire-free environment to prevent the charger from overheating or causing a fire.

Use a dedicated charger: Make sure to use the dedicated charger recommended by the manufacturer and avoid using incompatible or unreliable chargers.

Regular inspection and maintenance: Regularly inspect the appearance, circuits and interfaces of the charger to ensure there is no damage or aging. If necessary, replace the damaged parts in time.

Follow the instructions: Operate strictly in accordance with the charger's instructions to avoid problems caused by improper use.
