First, the battery monitoring module can not charge

The inability to charge the electric car may be caused by the failure of the battery monitoring module. The main role of the battery monitoring module is to monitor the battery status, when the charging current or charging voltage is too high, the battery monitoring module will automatically stop charging to protect the battery. If the battery monitoring module fails, the battery will not be charged. The solution is to check whether the battery monitoring module is damaged, if it is damaged, it needs to be replaced.

Second, the battery capacity display is not accurate

Inaccurate display of battery capacity may be caused by the failure of the battery monitoring module. The battery monitoring module calculates the battery capacity by detecting the battery’s charge, current and voltage and other parameters, if the battery monitoring module fails, it will lead to inaccurate capacity display. The solution is to use professional tools to test the battery monitoring module, if the failure needs to be repaired or replaced.

Third, the battery over-discharge protection failure

Battery over-discharge protection is one of the important functions of the battery monitoring module. Battery over-discharge protection can effectively protect the battery to avoid damage to the battery due to over-discharge. If the battery monitoring module fails, it may lead to the failure of the battery over-discharge protection function, thus causing damage to the battery. The solution is to check whether the battery monitoring module is malfunctioning, if it is malfunctioning, it needs to be repaired or replaced.

Fourth, the battery temperature is too high failure

High battery temperature may be caused by the failure of the battery monitoring module. The battery monitoring module will monitor the battery temperature, if the battery temperature is too high, it will stop charging or discharging to protect the battery. If the battery monitoring module is faulty, it may cause the battery temperature to become too high, which will affect the battery life. The solution is to check if the battery monitoring module is malfunctioning and if it is malfunctioning it needs to be repaired or replaced.

V. Other Failures

Battery monitoring module may also have other faults, such as not working properly, display abnormalities and so on. If these failures occur, you need to check whether the battery monitoring module is faulty in time to avoid more serious consequences.

In summary, the battery monitoring module is a very important component in the electric vehicle, and it needs to be dealt with in time if it fails. When dealing with faults, you need to use professional tools and techniques, and ensure that the operation process is safe and reliable.
