This innovation means the latest EVs from Hyundai and Kia offer around twice as much driving range and battery capacity compared to the their first-generation EVs – and are capable of travelling significantly further on a single charge. “So it’s going to make it more marketable, more attractive, and it’s going to take less energy.”. This process generates additional heat energy that is recovered by the heat pump and used to warm the cabin. A study carried out by Korea’s Ministry of the Environment on the Hyundai Kona Electric and Kia Niro EV found that the heat pump significantly reduced battery consumption in cold conditions. The test monitored the performance deviation of each vehicle in cold conditions compared to quoted manufacturer figures. The system has been gradually refined since its 2014 introduction through extreme cold weather testing in Northern Sweden, where temperatures can get as low as -35°C (-31°F) in the winter. The technology was first introduced in 2014 on the first-generation Kia Soul EV. I agree to receive emails from Green Car Reports. Hyundai and Kia said they are continuing to test and refine their heat-pump tech, hoping to make additional improvements for next-generation EVs. Blagojce Krivevski is physicist and green technology lover. One of the keys to a more efficient system is to develop stronger heat pumps. All Rights Reserved. It enables EV drivers to heat their car’s cabin in cold weather without significantly impacting electric driving range, unlike other EVs. That heat is what turns the liquid refrigerant into a gas. Hyundai and Kia’s heat pump is a leading heat management innovation that maximizes the distance that Hyundai and Kia EVs can travel on a single charge, scavenging waste heat to warm the cabin. Under its ‘Strategy 2025’ plan, Hyundai Motor aims to sell 670,000 battery EVs and FCEVs (fuel cell electric vehicles) annually and become a top-three EV manufacturer by 2025. Comprising a compressor, evaporator and condenser, the heat pump captured waste heat given off by the vehicle’s electrical components, recycling this energy to heat the cabin more efficiently. Hyundai and Kia are proud to use heat pumps in their electric cars since 2014 – when the Soul EV first presented it. One solution is the heat pump, an external vapor-compression system with an independent compressor and expansion valve. How it works: EV cabin heating without the energy drain. From that year on, the Korean brands have been only improving it to become one of their best tools in achieving high energy consumption efficiency. One solution is the heat pump, an external vapor-compression system with an independent compressor and expansion valve. Hyundai and Kia continue to develop their heat pump technology to yield even greater improvements in energy capture and efficiency. Hyundai and Kia are proud to use heat pumps in their electric cars since 2014 – when the Soul EV first presented it. According to the Electric Drive Transportation Association, a Washington, D.C.-based industry group, electric-drive vehicles accounted for a little more than 2 percent of annual car sales in the United States in 2011. Equipped with the latest heat pump technology, the Kona Electric proved this in a recent test in Norway, the most advanced EV market in the world. Hyundai and Kia’s heat pump technology made its debut six years ago on the first-generation Kia Soul EV. The heat pump is one of a number of innovations found in Hyundai and Kia’s current generation of EVs, with heat management also used to realise major improvements in EV battery packs. electric vehicles, such as a drainage problem regarding the external heat exchangers while in heat pump mode, and the decrease in heating performance when operated in a cold climate. According to the two companies, the first heat pump would get that heat from power electrics modules. (2) The unit combines an advanced heat pump with a “next-generation electric compressor.” Hyundai and Kia continue to hone and improve the heat pump system and other heat management innovations, with the technologies currently informing the development of next-generation EVs from each brand. Hyundai and Kia honing heat-pump tech for next-generation EVs, turned to the use of heat-pump technology, after resisting the cost and weight in the past (but accomplishing, Hyundai plans to sell 670,000 battery-electric and hydrogen fuel-cell cars by 2025, and become a top-three EV manufacturer. A study from Korea’s Ministry of the Environment showed the Hyundai Kona Electric and Kia Niro EV kept 90 percent of their driving range “in temperatures of -7°C (19°F) with the HVAC system activated.” Other EVs without the heat pump had drops going from 18 percent to up to 43 percent when submitted to the same tests. High-pressure gas is discharged from the compressor and forced into a condenser to be converted back into a liquid.
