Hyundai And Kia Introduce Innovative Technologies For Optimal Temperature Control
Hyundai Motor Company and Kia Corporation have introduced three innovative technologies aimed at enhancing passenger comfort and energy efficiency in vehicles. These advancements were revealed during ‘Heat Tech Day’ in Seoul, South Korea, highlighting the companies' commitment to improving in-vehicle conditions through advanced temperature control systems.
The new technologies include Nano Cooling Film, Radiant Heating System, and Metal-Coated Heated Glass. Each of these innovations is designed to regulate the vehicle's interior temperature efficiently, providing a more comfortable environment for passengers while conserving energy. This is particularly important as vehicles transition from mere transportation modes to living spaces.
Young Ho Jung, Vice President and Head of Thermal Energy Total Development Group at Hyundai Motor Company, stated, "The three technologies unveiled today are closer to customers than any other technology. We are developing technologies to provide the most pleasant environment, considering every moment that customers experience in mobility."
The Nano Cooling Film significantly lowers the interior temperature of vehicles by over 12°C. This film blocks infra-red radiation from outside while allowing heat to escape from inside the vehicle. It consists of three layers: two reflecting solar energy and one emitting mid-infrared wavelength. This technology can be combined with existing tinting films without affecting light transmission.
In July 2023, Hyundai Motor and Kia demonstrated this technology by applying it to some vehicles while leaving others unchanged. The results showed that vehicles with Nano Cooling Film had an interior temperature of 36.0°C compared to 48.5°C for those without it, showcasing a maximum reduction of 12.5°C.
Radiant Heating System: Quick Warmth in Winter
The Radiant Heating System quickly warms passengers during cold weather by emitting radiant heat towards their legs. This system works alongside the vehicle’s existing heating system and can save up to 17 percent more energy while reaching the desired temperature faster. It delivers warmth within three minutes, significantly enhancing passenger comfort.
This system includes a high-temperature film-type heating element wrapped in fabric material that emits infra-red rays. A burn prevention system detects body contact and immediately lowers the temperature to prevent burns. The Radiant Heating System is expected to extend the driving range of electric vehicles in winter by reducing climate control energy usage.
Metal-Coated Heated Glass: Enhanced Visibility
The Metal-Coated Heated Glass system uses a world-first 48V technology for fast defrosting of windows, improving visibility and safety during winter. This invisible coating provides a clear view without distortion and can defrost glass surfaces within five minutes at -18°C, consuming about 10 percent less energy than conventional systems.
Additionally, on hot days, this metal coating can block at least 60 percent of solar energy passively, reducing cabin cooling requirements and improving overall energy efficiency. Hyundai Motor and Kia have applied for patents for this technology in major markets worldwide.
These advancements reflect Hyundai Motor and Kia’s dedication to enhancing passenger comfort while promoting energy efficiency in their vehicles. As they continue to innovate in temperature control technologies, they aim to meet the evolving needs of modern mobility.
