Hyundai Tests Kona Electric And NEXO Eco Crossovers In The Snow Of Lapland
After the presentation of the compact Kona Electric SUV and the NEXO hydrogen off-road vehicle at the Motor Show in Geneva on March 6, 2018, Hyundai Motor Company sent its eco cars to Sweden, where they pass road tests on snow-covered routes of the Hyundai Mobis test center at temperatures below 30°C .
To test how the powertrains and batteries of the new Kona Electric and NEXO models behave in extreme cold conditions, Hyundai Motor Company sent both debutants of the Geneva Motor Show to the road tests in Aryehlug (Sweden), where the Hyundai Mobis is located.
TA key challenge for the Kona Electric during the tests was to achieve the most efficient use of electricity. To increase the power reserve in conditions of extreme frosts, the electric crossover was equipped with HVAC technology. It minimizes the loss of electricity used for heating, ventilation and air conditioning in the cabin.
The effectiveness of this technology is justified by the use of a high-performance new generation heat pump, intelligent systems to control air intake flaps, individual ventilation (only for the driver) and pre-conditioning.
The Kona Electric heat pump uses the heat generated by the electrical components of the powertrain and directs it to heat the cabin, thereby minimizing battery power consumption.
The intelligent air intake flap control system, presented on the Kona Electric, efficiently distributes heated air, controlling the amount of air entering and leaving the car.
Due to improved control of the airflow inside the vehicle, the HVAC system is able to heat the cabin faster, thereby minimizing the amount of electricity from the battery, used during winter driving.
The individual ventilation system of the Kona Electric completely disconnects the heating and ventilation on the passenger side, directing warm or cold air only to the driver. It allows to reduce power consumption much and, as a result, increase the SUV’s driving range.
Hyundai Kona Electric has got a unique heating system for the cabinDuring battery charging, the pre-conditioning system lets preheat or cool the air in the cabin of the Kona Electric, using electricity from the network. Owners of the electric car will be able to program the time of preheating or cooling switch on before the trip.
How does the hydrogen Hyundai NEXO fight the frost?
Previous generations of FCEV models have faced a serious technical problem – effective operation at temperatures ranging from -10° to -20°C. To solve this problem, Hyundai engineers have developed a new heating system for the NEXO hydrogen fuel cell power pack, which allows, in particular, to start the crossover engine at a temperature of -30°C.
Another technical problem, usually found on FCEV models, is the formation of ice in the fuel cell power pack after the vehicle has stopped. The glaciation is due to condensate, which is formed as a result of the powertrain work, since water is the only release in hydrogen crossovers.
Hyundai engineers solved this problem by mounting a special fan heater on the fuel cell power pack. When the car stops, the fan heater is activated, and the warm airflow removes the condensate from the pack to the formation of ice.
After the completion of road tests in Lapland, crossovers will be tested in regions with a temperature regime above 30° C and high humidity.
