At Hyundai Mobis Proving Ground in Sweden, just an hour’s drive away from the Article Circle, Hyundai Motor Company subjects its latest electrified vehicles to the most extreme sub-zero conditions. Rigorous testing ensures winter-proved operation of Hyundai’s electrified vehicles in temperatures as low as -35°C.
Extreme cold can adversely affect various functions of electrified vehicles, such as the ability to start the vehicle, manage thermal control of the electric powertrain, heating and ventilation and maximize the drive range.
Hyundai’s two prominent electrified vehicles, Hyundai NEXO fuel cell electric vehicle (FCEV) and All-New Kona Electric, spearheaded the Hyundai’s winter test.
The other technical challenge typically found with FCEVs is ice formation within the fuel cell stack after the vehicle is turned off, as water is the only byproduct of electricity generation through hydrogen. Utilizing a blower system attached to the fuel cell stack, when it is turned off, the NEXO removes water before it becomes frozen.
The Kona Electric’s heat pump system harnesses wasted heat emitted by electrical components and recycles it to increase the efficiency of the heating and ventilation systems. By minimizing electricity consumption from the battery, the heat pump contributes to the overall driving range of the Kona Electric in winter.
When plugged in, the pre-conditioning ventilation system allows the Kona Electric to be pre-heated, utilizing electricity from the grid before the car is driven. Customers can schedule to pre-heat or pre-cool the cabin of their vehicles before driving.
At the apex of Hyundai’s eco-friendly vehicle line-up, Hyundai’s first dedicated hydrogen-powered SUV, the NEXO boasts the best range within the fuel cell and EV car segments, delivering an estimated 800 km from a single charge (under NEDC testing).
