HYBRID BATTERY SYSTEM


  1. CONSTRUCTION


    1. The HV battery mainly consists of the HV battery (5 battery stacks), No. 1 to No. 5 HV battery voltage detection wire, HV battery junction block assembly, battery cooling blower assembly, battery ECU assembly and service plug grip.

    2. The HV battery uses plastic container type cells. As a result, high power density, lightweight construction, and longevity have been accomplished at high levels.

    3. The battery cooling blower assembly is used as a dedicated cooling system to ensure that the HV battery performs properly, despite it generating significant heat during the repetitive charge and discharge cycles.

      1. No. 1 HV Battery Voltage Detection Wire to No. 5 HV Battery Voltage Detection Wire


        1. 3 thermistor type battery temperature sensors are provided in each the HV battery detection wires.

        2. The thermistor type intake air temperature sensors is provided in No. 3 and No. 4 HV battery voltage detection wire to detect the temperature of the cooling air.

        3. The battery ECU assembly optimally controls the cooling system so that the HV battery temperature can be within a specified range according to the temperature information.

      2. Battery Heater


        1. The battery heater wire is sewn into a non-woven fabric which is laminated between insulating polycarbonate boards.

        2. Each heater uses a different wiring pattern to evenly distribute heat to each HV battery cell when heating the battery.
