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.
Measure the pressure of high pressure line by measuring voltage output between terminals No. 1 and No. 2.
2.
Inspect the voltage value whether it is within the specified range.
Voltage = 0.00878835 * Pressure + 0.5[PSIA]
3.
If the measured voltage value is not within t ...
General Inspection
After or before servicing the EPS system, perform the
troubleshooting and test procedure as follows. Compare the system
condition with normal condition in the table below and if abnormal
symptom is detected, perform necessary remedy and inspection.
