As winter sets in, electric vehicle drivers experience reduced battery performance due to increased resistance in cold temperatures, potentially lowering range by 15 to 25 percent. To mitigate this, drivers can preheat their vehicles, use selective heating, and park in warm garages. Maintaining a steady driving style and minimizing energy use from non-essential systems can help extend range. Pedelec users should also keep batteries warm and switch to Eco mode to conserve energy during colder months.
E-Autos in Winter: Understanding Range Loss
As winter approaches, electric vehicle (EV) drivers may notice a drop in battery performance. This is primarily due to increased electrical resistance in batteries when exposed to cold temperatures. As explained by Andreas Richter from the Dekra Competence Center for Electromobility, many drivers in the past resorted to warming their batteries overnight in a heated garage to ensure reliable starts in the morning.
The impact of colder weather on range can vary significantly between different EV models. When temperatures fall, the internal resistance of the battery rises, leading to a reduction in the typical range that electric vehicles can achieve. However, with temperature-managed batteries, both electric cars and e-bikes can maintain a better performance.
According to ADAC, drivers can anticipate a decrease in range averaging between 15 to 25 percent in cold conditions around freezing. In harsher sub-zero temperatures or during frequent short trips, this range reduction can be even more pronounced. Thankfully, newer electric vehicles come equipped with advanced technology and practical tips that help drivers stay efficient and safe on the road, even in winter.
Maximizing Efficiency: Tips for Winter Driving
Heating is a significant energy consumer in electric vehicles, second only to propulsion. To enhance winter driving efficiency, it is advisable to park in a warm garage or preheat the vehicle while connected to a charging station. Some electric cars allow for selective heating of only the areas in use, which conserves energy and enhances overall range.
Instead of heating the entire cabin, consider using seat and steering wheel heaters while lowering the cabin temperature to around 18 degrees Celsius, rather than the usual 22 degrees. Additionally, parking in a garage can help maintain battery warmth, as cold batteries are less efficient at absorbing energy. For optimal performance, driving in Eco mode can also contribute to extending your range.
During stops, be mindful not to leave doors open for extended periods to avoid the need for reheating the interior. Parking in a warm underground garage can further improve range, and using opportunities to recharge while on the road is always a wise strategy.
Small power consumers, such as lights and audio systems, have minimal impact on range, according to Dekra. However, it’s important to prioritize safety over energy conservation. Richter warns against waiting too long to turn on headlights in low visibility conditions or neglecting ventilation to clear fogged windows, as these actions can compromise safety.
Concerns about freezing in traffic jams with electric vehicles are largely unfounded. With a sufficiently charged battery, an electric car can maintain interior warmth for many hours, similar to traditional combustion engine vehicles. ADAC tests indicate that maintaining a comfortable 20 degrees Celsius inside the vehicle at an outside temperature of minus 10 degrees requires approximately 1.5 to 2 kW of power, which is manageable for most modern electric cars.
In general, ADAC recommends that all drivers, regardless of vehicle type, stay aware of traffic conditions, maintain ample reserves in their battery or fuel tank, and keep a blanket in the vehicle for emergencies.
Essential Tips for Extending Your Electric Car’s Battery Life:
- Park your electric vehicle in a garage during winter.
- Consider preheating the vehicle using energy from an outlet for optimal range.
- Heat only the areas of the vehicle that are in use whenever possible.
- Take advantage of opportunities to recharge while on the go.
- Adopt a steady driving style to improve range.
- Avoid leaving doors open for too long during stops.
- Never compromise on safety.
Enhancing Pedelec Range in Winter
Pedelec enthusiasts should also prepare for diminished range during the colder months. To maximize distance, it is advisable to keep the battery indoors until just before use. Research from Dekra suggests that using a thermal protective cover can help retain heat in the battery, ultimately extending its range. If the battery runs low during a ride, switching to Eco mode can help conserve energy and allow for a few more kilometers.
