CHARGING SYSTEM


  1. SYSTEM CONTROL


    1. This system controls the voltage in order to maintain the capacity of the auxiliary battery optimal condition when auxiliary battery capacity is high, then reduces the power consumption of the vehicle by controlling generated voltage of DC-DC converter.

    2. This control consists of battery sensor (battery state sensor assembly), DC-DC converter, switches and hybrid vehicle control ECU.

    3. The hybrid vehicle control ECU stops charging control and the DC-DC converter switches to the constant voltage control mode under the following conditions:


      1. Low auxiliary battery capacity

      2. Low or high auxiliary battery temperature

      3. A cooling system for the inverter with converter assembly, the hybrid transaxle and the HV battery is in high duty, or high engine load

      4. Battery sensor (battery state sensor assembly) malfunction

      5. Communication failure (LIN communication between the hybrid vehicle control ECU and the battery sensor (battery state sensor assembly))

      6. Accumulated driving time becomes approximately about 20 hours.

      7. Voltage sensing failure
