The provided image is a comprehensive technical diagram illustrating an Electric Vehicle (EV) Thermal Management System (Cooling & Sensor Control), detailing how fluid circuits, heat exchangers, and sensors regulate temperature across the battery pack, motor, inverter, and cabin.
Main Subsystems & Components
• Cooling & Heat Exchange Units
• Radiator & Radiator Fan: Cools the liquid coolant using ambient air flow.
• Chiller: Transfers heat from the coolant loop to the A/C refrigerant loop to cool the battery.
• HVAC Compressor & Expansion Valve: Compress and regulate refrigerant flow for cabin and battery cooling.
• Evaporator & Cabin Heater: Cool (dehumidify) or heat the cabin air.
• Motor/Inverter Cooling Jacket: Circulates fluid directly around the electric motor and power electronics to prevent overheating.
• Pumps & Reservoirs
• Coolant Pumps (Battery Loop & Motor/Inverter Loop): Dynamically circulate liquid coolant through separate thermal loops.
• Coolant Reservoir (Expansion Tank): Maintains proper coolant level and system pressure.
• Sensors & Control (BTMS)
• Battery Thermal Management Controller (BTMS): The central electronic control unit managing temperature thresholds, pumps, and valves.
• Temperature Sensors: Monitor multiple points across the battery pack, motor, inverter, coolant lines, cabin, and ambient air.
• Pressure & Flow Sensors: Track coolant flow rate, coolant pressure, and refrigerant pressure.
• Humidity Sensor: Measures interior cabin humidity for climate control optimization.

If you'd like to dive deeper, let me know:
• Would you like to know how the high-temperature vs. low-temperature loops separate?
• Are you interested in how the system adapts during fast charging vs. cold winter driving?
