Smart Battery Power Sensor
Three physical quantities, voltage (U), current (A), and temperature (T), are collected from the negative pole of a 12V lead-acid battery installed in a vehicle. A microprocessor (μC) then uses an internal software algorithm to perform real-time estimations, thereby obtaining the battery's state of charge (SOC), state of health (SOH), and state of function (SOF). This information is sent to the upstream control unit (ECU) via LIN communication, facilitating energy management and enabling engine start-stop functionality and intelligent alternator control. This reduces CO2 emissions and fuel consumption.

Product Details
Application Range:
Start-stop system for traditional vehicles, STOP&START
12V enhanced VLRA battery on 48V vehicles
12V battery on PHEV or HEV vehicles
12V battery on EV vehicles
Principle:
Installed on the negative pole of the vehicle's 12V lead-acid battery, it collects three physical quantities: voltage U, current A, and temperature T. The microprocessor μC then uses an internal software algorithm for real-time estimation to obtain the battery's state of charge (SOC), state of health (SOH), and state of function (SOF). Through LIN communication, it sends the relevant information to the upstream control unit ECU, which helps in energy management and enables engine start-stop functionality and intelligent alternator control, reducing CO2 emissions and fuel consumption.
Advantages:
Energy storage during driving and analysis during battery interruption help reduce the risk of failures due to insufficient voltage:
Displays battery power, monitors battery SOC status, and reminds customers to replace the battery to avoid vehicle failure due to insufficient battery power or severe aging.
It adopts a compact and economical design and is highly flexible, making it suitable for various cable types and integrated solutions.
The advanced battery algorithm used by the sensor supports a wide variety of battery types, providing a cost-effective integrated solution for vehicles.
