As a key component for monitoring the battery status, the failure of the battery sensor will have an adverse effect on the battery life and safety. The following are some signs that may be observed when there is a problem with the battery sensor:
- During the discharge process, if the battery capacity is found to decrease rapidly, and the high-speed discharge meter shows a sharp drop in battery voltage, this may be a sign of sensor failure.
- When the electrolyte density is lower than the standard value, this indicates that the battery may not work properly, which may also be related to sensor failure.
- If the battery voltage is detected to be abnormally high at the beginning and end of charging, exceeding 2.7V, this will cause the battery to overheat and pose a safety hazard, which may be caused by sensor failure.
- During the battery charging process, if the electrolyte temperature rises rapidly, exceeds 45 degrees, and bubbles appear at the beginning of charging, this will shorten the battery life, which may also be a manifestation of sensor problems.
- If hard and insoluble white particles are found on the battery board, this may affect the battery performance and even cause the battery to be scrapped, which may also be related to sensor failure.
In order to avoid battery performance degradation and potential safety risks, once the battery sensor shows signs of failure, it should be replaced immediately to ensure the normal operation of the battery and driving safety.
