Smart battery level sensor
The start-stop system of traditional cars, STOP&START
12V enhanced VLRA battery in 48V car
12V battery in PHEV or HEV car
12V battery in EV car
Installed on the negative pole of the car’s 12V lead-acid battery to collect the three physical quantities of voltage U, current A and temperature T, the microprocessor μC then estimates in real time according to the internal software algorithm, the battery’s state of charge (S0C) and health can be obtained. State (SOH) and State of Function (SOF), through LIN communication, send the relevant information state to the upstream control unit ECU to facilitate energy management, and realize the start-stop function of the engine and the intelligent generator control function, and reduce CO2 emissions , Reduce fuel consumption.
Storing energy during driving and analyzing during battery interruption can help reduce the risk of failure due to insufficient voltage:
Display the battery power, monitor the battery S0C status, and remind customers to replace the battery to prevent the vehicle from being unable to start due to insufficient battery power or severe aging.
It adopts a compact and economical design and gives it maximum flexibility, making it suitable for a variety of different cable styles and integrated solutions.
The advanced battery algorithm used by the sensor can support a wide range of battery types, bringing a very cost-effective integration solution for vehicles.
