Driving vehicles in extreme cold temperatures, such as -55 °C (-67 °F) in Yakutia, Siberia, presents unique challenges. These conditions impact all car types—hybrids, plug-in hybrids, and electric vehicles (EVs)—but with proper preparation, it’s possible to operate them effectively.
Let’s break it down:
Challenges for Cars in Extreme Cold
Battery Performance:
Hybrid and Plug-in Hybrid Cars: Reduced battery efficiency due to cold temperatures. The internal combustion engine (ICE) in hybrids helps maintain performance, but plug-in hybrids (PHEVs) might rely on ICE more frequently as the battery loses capacity.
Electric Cars: EV batteries can lose 30-50% of their range in extreme cold due to increased energy consumption for cabin heating and the slower chemical reactions in lithium-ion batteries.
Oil and Lubricants:
ICE components in hybrids and PHEVs can face thickened engine oil, making it harder to start and operate.
Tire Performance:
Rubber hardens in extreme cold, reducing traction. Special winter tires are essential.
Charging Issues:
EVs and PHEVs require charging, but charging times can increase in cold weather. The charging infrastructure also needs to be designed to handle low temperatures.
Freezing of Fluids:
Windshield washer fluid, coolant, and brake fluid can freeze if not rated for such extreme conditions.
Interior Heating:
Electric heating systems in EVs and hybrids consume significant energy, reducing efficiency and range.
How Cars are Driven in -55 °C
Pre-heating Systems:
Cars are equipped with block heaters for ICEs and battery heaters for hybrids and EVs. These systems warm the engine and batteries before starting the vehicle.
Parking and Storage:
Cars are parked in heated garages or covered parking spots to prevent them from freezing completely.
Battery Management:
EVs and PHEVs often have thermal management systems to maintain the battery temperature. Drivers preheat the cabin while the car is still plugged in to reduce energy loss from the battery.
Fuel Efficiency Adjustments:
Hybrids and PHEVs tend to rely more on their ICEs in extreme cold, reducing the reliance on electric-only operation.
Tires and Traction:
Specialized winter tires designed for subarctic conditions are mandatory for optimal grip.
Cold-Resistant Fluids:
Engine oil, coolant, and washer fluid designed for extreme cold are used to prevent freezing.
Routine Maintenance:
Frequent checks on the battery, tires, fluids, and brakes are necessary to ensure the vehicle performs well in the harsh conditions.
How Hybrid, PHEV, and EV Perform in Yakutia
Hybrid Vehicles:
Reliable because of the ICE as a backup. The battery’s reduced performance is less of a concern since the engine compensates. However, fuel efficiency drops as the ICE runs more often.
Plug-in Hybrids:
Similar to hybrids but may see even greater reliance on the ICE due to the battery being used less in extreme cold. Pre-heating systems and block heaters are essential.
Electric Vehicles:
EVs are more challenging but not impossible to use. Reduced range and slow charging times are key concerns. Thermal management systems and regular charging are critical to keep the battery warm. Vehicles like the Tesla Model Y and Nissan Leaf with advanced battery heating systems perform better than older models.
Adaptations in Yakutia
In Siberia, drivers often:
Leave their engines running for extended periods to prevent freezing.
Use diesel-powered heaters for cabins and engines.
Insulate the engine bay and battery with thermal covers.
Install additional heating systems for EVs and hybrids.
Limit driving to short distances to avoid being stranded far from help.
