Hanon Systems has unveiled the development of the first fourth-generation heat pump system designed for electric vehicles. This thermal management system has been commercially available since July.

The new pump system could be the first to employ a simultaneous heat recovery method. This breakthrough allows both waste heat from the engine and battery, as well as external heat from the air, to be reused for multiple applications. The recovered heat is redirected for vehicle heating and cooling, and at the same time, for battery thermal management.
“Constant improvement in the company’s heat pump system design has enabled it to optimize energy efficiency and reduce consumption, thereby extending the range of electric vehicles. As the world’s second largest thermal management supplier, Hanon Systems remains committed to developing lightweight, highly efficient components through continuous innovation.”
Subu Nagasubramony, co-CEO of Hanon Systems.
Among the innovations of the heat pump system is its modular design, which incorporates several patent-protected or patent-pending features, consolidating Hanon Systems’ leadership in thermal management. The system integrates the refrigerant control module(RCM) and refrigerant circuit control module(CCM) into a unified control unit, enabling comprehensive thermal system management.
Heat pump system advances
The company’s track record in the production of heat pump systems dates back to 2015, when they took on the mass production of systems with waste heat recovery. In 2018, they introduced their second-generation system, which added battery thermal management functions, becoming the first integrated system to improve the range of electric vehicles. Later, in 2021, they developed the third generation, which was implemented on a platform dedicated to electric vehicles and stood out for incorporating an 800 V electric compressor, reducing charging times and energy consumption.
The fourth-generation system has initially been implemented in the Kia EV3 in South Korea, and Hanon Systems plans to expand its production to the United States and Europe. Yoon Ho Wang, vice president of the AP Innovation Center at Hanon Systems Research Institute, noted that “close collaboration with our customers has enabled us to proactively develop this pioneering technology, and we are proud to enhance the driving experience for electric vehicle users.”
In addition, Hanon Systems has launched Thin HVAC (Heating, Ventilation and Air Conditioning) technology, a world first. Thin HVAC is a reduced HVAC system, which decreases the overall size of the system by 30%, providing more legroom for passengers and ensuring a more comfortable driving experience.
