HYBRID BATTERY CONTROL: HYBRID BATTERY SYSTEM: SYSTEM DESCRIPTION

SYSTEM DESCRIPTION

1. BATTERY SMART UNIT CONTROL

- The battery smart unit monitors the HV battery condition signals (voltage, current, and temperature), which are needed to determine the charging or discharging values that are calculated by the hybrid vehicle control ECU and transmits them to the hybrid vehicle control ECU via serial communication.
- A leakage detection circuit is provided in the battery smart unit in order to detect any leakage from the HV battery.
- The battery smart unit monitors the voltage of the cooling fan, which is needed by the hybrid vehicle control ECU to effect cooling fan control, and transmits it to the hybrid vehicle control ECU via serial communication.
