8ZR-FXE BATTERY / CHARGING  CHARGING SYSTEM  P058A01  Auxiliary Battery Monitor Module Range/Performance  


DESCRIPTION

The battery state sensor assembly detects the auxiliary voltage, current and temperature of the auxiliary battery. The battery state sensor assembly calculates State of Charge (SOC) based on the voltage and current of the auxiliary battery and sends it to the hybrid vehicle control ECU. Based on the signals received, the hybrid vehicle control ECU adjusts the charging voltage of the DC/DC converter.

The battery state sensor assembly calculates the auxiliary battery temperature based on changes in resistance of a built-in thermistor and sends it to the hybrid vehicle control ECU. The hybrid vehicle control ECU reduces the amount of charging current based on this signal in order to protect the auxiliary battery.
