Hanon Systems, the South Korea-based automotive thermal management supplier and subsidiary of Hankook & Company Group, has launched a highly integrated cooling entity (HICE) designed to consolidate multiple refrigerant-circuit components into a single compact module for battery electric vehicles.
Highlights
- Single-module integration: The HICE combines an eCompressor, electronic expansion valve block, water-cooled condenser, internal heat exchanger, chiller, A/C lines, and pressure/temperature sensors into one unit.
- First deployment: The system debuted on BMW’s fully electric iX3 SUV.
- Compact footprint: The module weighs just 16 kg (35 lbs) and dynamically regulates refrigerant flow to support fast charging, high-performance driving, and extreme weather conditions.
- NVH-conscious design: Vibration isolation components and a sound cover address noise, vibration, and harshness concerns.
How the HICE Works
The module manages thermal demands across multiple vehicle subsystems through intelligent, real-time refrigerant flow regulation. Rather than relying on separate components connected by traditional refrigerant lines, the HICE consolidates those functions into a single high-power-density package.
That consolidation delivers packaging and material savings while improving overall thermal efficiency. According to the company, the design also reduces system complexity and enhances energy utilization — factors that contribute to extended driving range.
NVH and Scalability
Beyond thermal performance, Hanon Systems incorporated NVH-specific design elements into the module. Vibration isolation components and a sound cover help minimize cabin noise.
The company also designed the HICE for scalable production and efficient vehicle assembly. Hanon Systems said the module’s architecture supports adaptability across a wide range of BEV platforms.
CEO Comments
“By unifying all critical refrigerant thermal management functions into one exceptionally compact module, we achieve savings in both packaging and materials,” said Soo Il Lee, chief executive officer of Hanon Systems. “The company is committed to delivering innovative technologies that shape the future of electric mobility and contribute to a more sustainable future.”
Company Background
Hanon Systems was founded in 1986 and became a subsidiary of Hankook & Company Group in January 2025. The company operates 50 manufacturing sites and three regional innovation centers across 21 countries, employing more than 20,000 people. Its product portfolio spans HVAC, powertrain cooling, compressors, fluid transport, and electronics and fluid pressure systems.
