It is normal for the battery of an electric vehicle to slightly heat up during charging, as there will be current passing through during the charging process, generating a certain amount of heat.
If the battery heats up abnormally, such as overheating or high temperature, it may indicate problems such as excessive charging current, battery aging, poor heat dissipation, etc. At this time, it is necessary to check and handle it in a timely manner.
During the charging process, attention should be paid to observing the temperature changes of the battery to ensure that it is within the normal range, in order to avoid battery damage or safety accidents caused by overheating.
