The Xiaomi SU7 features a highly integrated thermal management system designed to optimize the temperature control of the cabin, battery pack, and electric drive system. Central to this setup is the implementation of a 9-way valve that allows dynamic coolant routing across multiple components. With support from various domain controllers and smart actuators, the system enables efficient operation under different thermal scenarios—such as heat pump mode, cabin cooling, battery cooling, and motor heat dissipation. This article explores the structure, components, and working modes of the SU7’s thermal architecture in detail.
