How To Determine If The Battery Negative Electrode Sensor Is Damaged?

The battery status sensor is often installed at the cathode of the battery, and it plays an important role in monitoring the battery's current strength, voltage value and temperature condition. Many cars are equipped with a current sensing device at the cathode connection point to monitor the current of the vehicle battery and adjust its charging method according to the battery's usage status. Nowadays, some models are also equipped with an intelligent start-stop system, in which the current sensor can issue an indication to determine whether the start-stop operation is appropriate. However, once the sensor at the battery cathode fails, the dashboard will not be able to display the alarm information normally. Although under normal circumstances, this type of failure will not hinder the normal starting process of the car, it may cause the function to fail for vehicles equipped with an intelligent start-stop system. In addition, the generator's power generation regulation may also be affected and cannot be performed normally.
