Purpose of Focus battery negative electrode sensor

The battery sensor is generally installed at the negative electrode of the battery, and its main function is to detect the current, voltage and temperature of the battery. Generally, vehicles will install a current sensor at the negative terminal, mainly to detect the battery current of the vehicle, and then switch the charging mode according to the battery usage. Now vehicles have a start-stop function, and the current sensor will also be used as a signal to determine whether it can be started and stopped.
Generally, vehicles with a start-stop function have a battery sensor. The function of the battery sensor is to determine the charging current of the charger by detecting the temperature of the battery. If the battery temperature is high, the current will increase at the same voltage, causing the battery to be overcharged and damaged in advance. If the battery temperature is too low, the discharge current will decrease, which may affect the start. By testing the temperature, the ignition system can increase the starting current of the battery by adjusting the system resistance, thereby ensuring the start of the car.
