Ensure Optimum Cabin Temperature Control with BMW iX's Thermal Management System and Tesla's Overheat Protection Feature.
BMW iX has an integrated heating and cooling system with heat pump function, anticipatory thermal management for the battery. This system comprises three cooling/heating circuits that can be interconnected by means of electric valves with a shared expansion tank. The BMW iX is designed to use the excess heat generated by the drive units to warm up the high-voltage battery while driving at low outside temperatures. A two-level cooling module, a refrigerant compressor, two evaporators, a water-cooled condenser and a high-performance control unit together ensure optimum temperature control for both the BMW eDrive components and the cabin.
The Tesla Cabin Overheat Protection feature can be toggled: Off, No AC, With AC. In almost all climates the No AC option will suffice and does not drain the battery much. However, even when this feature is off, it may still turn main battery contractors to recharge 12V battery because cabin fan even AC is off will draw enough current to call for 12V battery recharging. To avoid this issue, windshield sunshades are the best alternative.
In conclusion, BMW iX has an advanced thermal management system that ensures optimum temperature control for both the BMW eDrive components and the cabin. It also uses an efficient heat pump function to warm up the high-voltage battery while driving at low outside temperatures. On the other hand, Tesla offers Cabin Overheat Protection feature which can be toggled: Off, No AC, With AC. Windshield sunshades are also recommended as an alternative solution to prevent draining of the battery due to cabin fan or AC running.
Does the BMW iX have an automatic thermal battery management system?
The BMW iX is equipped with an integrated heating and cooling system for the cabin, together with its high-voltage battery and its drive system that operates using an exceptionally efficient heat pump function. This system comprises three cooling/heating circuits that can be interconnected by means of electric valves with a shared expansion tank. While driving at low outside temperatures, for example, the excess heat generated by the drive units is used to warm up the high-voltage battery.
Is this system related to preconditioning the battery?
Yes, it is related to preconditioning the battery "on the way" to the fast charging station by using the Nav system.
What about Tesla's feature of running AC when parked in hot sun?
Tesla Cabin Overheat Protection can be toggled: Off, No AC, With AC. In almost all climates the No AC option will suffice and does not drain the battery much. However, it will still turn main battery contractors to recharge 12V battery because cabin fan even AC is off will draw enough current to call for 12V battery recharging. Windshield sunshade are best alternative to this type of issue.
