This article outlines the key design considerations for R290 electric compressor applications, focusing on system safety, sealing performance, operating envelope, structural strength, motor and power electronics reliability, and lubricating oil compatibility. The insights presented aim to support engineers and OEMs in developing safe, efficient, and reliable R290-based electric compressor solutions.

This article provides a comprehensive system-level analysis of their operating conditions, covering vehicle electrical architecture, high- and low-temperature challenges, startup performance, and the transition to eco-friendly refrigerants like R290. Key design considerations include electromagnetic interference mitigation, power sequencing, insulation requirements, and adaptations for higher speeds and larger displacements. By examining these factors, the article highlights essential strategies for developing reliable and efficient electric compressors tailored to the demands of modern EV thermal management systems.

This article explores two transformative industry trends: the integration of thermal systems—combining multiple functions into compact, energy-efficient modules—and the adoption of carbon dioxide (CO2 or R744) heat pumps as eco-friendly, high-performance alternatives to traditional heating methods.

With a GWP of just 3 and zero ozone impact, R290 (propane) delivers powerful, energy-efficient cooling—cutting EV compressor load by up to 30%. Advanced safety innovations like flame-retardant hoses, leak sensors, and automatic shut-off valves are unlocking its full potential. R290 is cost-effective, eco-friendly, and ready to drive the next generation of sustainable vehicle HVAC systems.

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.
