Cooling System,
Why do the engine and hybrid system need independent cooling systems?
Q. Why do the engine and hybrid system need independent cooling systems?
A. Because the target cooling temperature differs for both the engine and hybrid system.
The engine and hybrid system have independent cooling systems
Due to differing target cooling temperatures, the engine’s cooling system is designed to maintain an engine coolant temperature within 80 °C to 100 °C (176 °F to 212 °F) after warming up, the same as conventional engines, and hybrid system is designed to keep less than approximately 65 °C (149 °F), particularly for cooling down the inverter.
