CONSTRUCTION
The battery state sensor assembly installed on the negative (-) auxiliary battery terminal calculates the current, voltage, battery temperature, SOC (battery charging percentage) and SOH (battery degradation percentage) and sends these signals to the hybrid vehicle control ECU via LIN communication.
To detect the current, a shunt resistor installed inside the battery state sensor assembly is used to convert and calculate the voltage generated in the shunt resistor due to the battery charge and discharge current.
The auxiliary battery temperature is calculated from the resistance value of the thermistor built into the battery state sensor assembly.
