Hanon Systems' new heat pump system increases EV range

SEOUL: South Korea's Hanon Systems, a leading global automotive thermal management supplier for electrified mobility, has announced the development of the world's first fourth generation heat pump system, a key thermal management component for electric vehicles (EVs).

The new heat pump system has been commercially available since July.

The company's new heat pump system is the first to employ a parallel heat source recovery method, using waste heat from the motor and battery as well as heat from external air.

The recovered heat is used for both heating and cooling, as well as battery temperature management, significantly enhancing EV driving range.

The system combines the Refrigerant Control Module (RCM) and Coolant Control Module (CCM) into a unified unit, offering comprehensive thermal system management.

According to co-CEO Subu Nagasubramony, the company’s ongoing improvements in heat pump design have contributed to extending electric vehicle (EV) driving range by enhancing efficiency and reducing power consumption.


Hanon Systems, the world’s second-largest thermal management firm, aims to continue developing lightweight and high-efficiency components through innovation.

Hanon Systems began mass production of heat pump systems with waste heat recovery in 2015.

The second generation, launched in 2018, introduced battery thermal management, while the third generation, developed in 2021, featured an 800V electric compressor, reducing EV charging times.

The latest system was first implemented in the Kia EV3 in South Korea, with plans for expansion to the US and Europe.

In addition, Hanon Systems has unveiled the Thin HVAC technology, reducing HVAC system size by 30%, increasing passenger legroom and enhancing driving comfort.

Hanon Systems operates 50 manufacturing sites and three regional innovation centres, employing over 20,000 people in 21 countries.
