The sensor detects the current, voltage and temperature of the battery. It is the first battery sensor based on the CAN bus, which can accurately measure and monitor the voltage, current and temperature of lead-acid and lithium-ion batteries, and can also calculate the remaining time of the battery when the car is in poor working conditions.
A sensor (English name: transducer/sensor) is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required information output according to certain rules, so as to meet the requirements of information transmission, processing, storage, display, recording and control.
The principle of the negative electrode sensor is to check the voltage, current and temperature of the battery by checking the current flowing through the battery. If the car has an automatic start-stop function, the negative electrode sensor of the battery can also determine whether the car has an automatic start-stop function by sensing electrical signals.
When the battery temperature is too high, the current in the battery will increase, the battery will be overloaded, causing failures, and in severe cases, it may be directly scrapped.
When the battery temperature is too low, the current in the battery will decrease, and the battery may lose power, which will affect the normal start of the car engine.
