As the UK embraces EV technology as part of the transition to sustainable travel, EVs are praised for their efficiency and lower environmental impact. However, electric vehicles can be less efficient in colder weather.
We’ve explored how to use an electric vehicle in winter in depth, offer tips for mitigating the effects of cold weather on your EV, and highlight EV models that fare best in low temperatures.
The Science Behind Cold Weather and EV Batteries
EVs rely on lithium-ion batteries to store and deliver energy, and these batteries operate optimally between 15°C and 25°C. When temperatures drop below this range, chemical reactions inside the battery slow down, reducing its efficiency. Cold weather also increases the battery’s internal resistance, which can reduce range by up to 33%.
Impacts of Cold Weather on EV Range
One of the most noticeable effects of cold weather is a decrease in range. This happens because:
Increased Energy Demand: Heating the cabin, defrosting windows, and running heated seats consume significant amounts of energy.
Reduced Regenerative Braking Efficiency: Cold weather can limit the regenerative braking system, which recharges the battery during deceleration.
Lower Battery Efficiency: Chemical reactions in the battery slow down in cold temperatures.
Charging Challenges in Cold Weather
Charging an EV in the winter can be slower and less efficient due to the battery management system prioritising heating the battery. Fast charging stations are often less effective in cold weather, as rapid energy input can strain a cold battery, causing it to limit the charging rate for protection.
Long-Term Effects on Battery Lifespan
Repeated exposure to cold weather without sufficient thermal management can accelerate battery degradation. While modern EVs come equipped with battery management systems to regulate temperature, improper charging habits or lack of preconditioning can exacerbate wear and tear. Over several years, this can translate to reduced capacity and overall performance.

Tips to Improve Winter EV Performance
While the effects of cold weather can’t be entirely avoided, there are steps drivers can take to mitigate them:
Precondition Your Vehicle: Use your EV’s preconditioning feature to warm the cabin and battery while still plugged into a charger. This reduces energy demand during the journey.
Plan Your Charging: Charge your EV overnight in a garage or sheltered area to maintain a higher starting temperature.
Utilise Eco Modes: Many EVs offer an “eco” mode that optimises energy consumption for longer range.
Use Heated Accessories Wisely: Opt for heated seats and steering wheels over cabin heating to conserve energy.
Keep Tyres in Good Condition: Ensure your tyres are properly inflated and consider winter tyres for improved efficiency and safety.
Used Electric Vehicles
Investing in a second-hand electric vehicle is a cost-effective way to embrace eco-friendly driving while enjoying the latest advancements in EV technology.
A used EV often provides excellent value, as they’re priced lower than new models, but still offer reliable performance to help navigate winter challenges. This means that you can access the more advanced technology, such as heat pumps and preconditioning systems, to combat range loss in cold weather.
Looking Ahead: EV Technology Advancements
Manufacturers are actively addressing the challenges posed by cold weather. Heat pumps, which are more energy-efficient than traditional resistive heaters, are becoming standard in many new EV models. Additionally, battery chemistries are evolving, with solid-state batteries promising improved performance in extreme temperatures.
Research and development into cold-resistant materials and more efficient thermal management systems are also paving the way for better winter performance.
