The system temperature is calculated by the BMS based on 8
temperature sensor signals. And the cooling fan is conrolled in 9 steps
to maintain the normal temperature of high voltage battery system.
The air-cooling method is applied in the cooling system where
indoor air is used to cool down the high voltage battery pack assembly.
Operation
Control Flow
Air Flow
1. Cooling fan operates.
2. Indoor air flows into the cooling duct (inlet).
3. Cools down the high voltage battery in the direction of the arrows.
4. Air is ventilated out through the cooling duct (outlet).
Inspection
1.
Turn the ignition switch OFF.
2.
Disconnect the temperature control actuator connector.
3.
Verify that the temperature control actuator operates to the
cool position when 12V is connected to terminal 3 and ground to terminal
7.
Verify that the temperature control actua ...
