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).
Refrigerant System Service Basics
•
Since the electric compressor uses high-voltage, POE oil with high volumetric resistivity should be used.
•
Do not use the same A/C recovery / charging station as in conventional belt-driven compressors.
