Judgment of the normal heating range of an electric vehicle charger after use

It is a normal phenomenon for an electric vehicle charger to heat up after use, as the current passing through the electronic components inside the charger generates a certain amount of heat. However, the degree of heat generation needs to be controlled within a certain range to ensure the safety of the charger and extend its service life. The following is a judgment on the normal range of heat generation after the use of an electric vehicle charger:

Normal fever range

Temperature range:

Under normal circumstances, the temperature of an electric vehicle charger during the charging process is generally between 40 and 60 degrees Celsius.

When the ambient temperature is relatively low (such as 25 degrees Celsius), the charger temperature usually does not exceed 45 degrees Celsius.

If the ambient temperature is high, the charger temperature may approach but should not exceed 60 degrees Celsius.

Sensory judgment

Slight heating: If you touch the charger's casing with your hand and feel it is only slightly warm, this is a normal phenomenon.

Excessive heating: If you feel that the charger casing is hot to the touch or even gives off a burnt smell, this is abnormal. You should immediately stop charging and check the charger and battery.

The causes of abnormal fever

The charger does not match the battery:

If an inappropriate charger is used, such as when the output voltage or current does not match the battery, it is easy to cause excessive heating.

Poor charging environment

Charging in a high-temperature and closed environment is not conducive to the heat dissipation of the charger, thereby causing the temperature to rise.

Charger quality issue:

Poor quality of the charger itself, aging or damage of internal components may also cause abnormal heating.

Long continuous charging time

Long-term continuous charging can cause the internal components of the charger to overheat, thereby increasing the risk of failure.

Suggestions for Safe use

Choose the appropriate charger:

The original charger that matches the battery should be selected, and the use of non-compliant third-party devices should be avoided.

Pay attention to the charging environment

When charging, choose an environment with good ventilation and suitable temperature, and avoid charging in high-temperature or closed environments.

Avoid prolonged continuous charging:

When charging, the charging time should be reasonably arranged according to the battery capacity and actual needs to avoid continuous charging for a long time. Unplug the charger in time after it is fully charged.

Check the charger regularly:

Regularly check the appearance and internal components of the charger for any damage or aging, and replace the faulty charger in time.

To sum up, it is normal for an electric vehicle charger to slightly heat up after use, but the temperature should not exceed 60 degrees Celsius. If you feel that the charger is overheated or there is an abnormal situation, you should stop charging immediately and check the charger and battery. At the same time, following the above safety usage suggestions can ensure the safety of the charger and extend its service life.
