- Electrified vehicles subjected to winter testing
- NEXO fuel cell electric vehicle boasts perfect cold start capability at -30°C
- Kona Electric benefits from energy saving heating and ventilation technologies
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 HVAC technologies highlighted in the Kona Electric are a highly efficient new heat pump, smart air intake control, individual ventilation (for driver only) and a pre-conditioning ventilation system.
Featuring two different battery capacity options, the long-range version Kona Electric with a 64 kWh battery pack is going to deliver up to 482 km of drive range on a single charge, whilst the basic version with a 39.2 kWh battery pack is going to deliver up to 312 km (under WLTP regulations).
