Nationwide Vehicle Contracts has put together a short blog explaining how weather conditions affect electric car efficiency and offering tips to mitigate their impact on miles per kWh

Electric cars have made a significant mark in the automotive industry, championing sustainability and paving the way for a greener future. As more individuals opt for electric vehicles, understanding the various factors affecting their efficiency is crucial. One of these factors, often overlooked, is the impact of weather conditions on electric car efficiency.

The Weather's Influence on Electric Car Efficiency

Weather can significantly influence how efficiently an electric car operates, affecting its overall range and miles per kilowatt-hour (kWh). Here's a breakdown of how different weather conditions impact an electric car's efficiency:

Cold Weather: Cold temperatures can reduce the efficiency of electric car batteries. When it's cold, the battery's capacity diminishes, resulting in a decrease in the car's range. Additionally, the need to heat the car's interior and defrost windows requires extra energy, further depleting the battery.

Hot Weather: High temperatures can also impact electric car efficiency. Heat can degrade the battery's longevity and performance, reducing the overall range. Air conditioning is a necessity in hot weather, consuming more energy and, subsequently, reducing the miles per kWh.

Rain and Humidity: Rain and high humidity don't significantly affect electric car efficiency, but they can impact aerodynamics and rolling resistance, slightly reducing range.

Tips to Mitigate the Impact

Despite the influence of weather conditions, there are several ways to mitigate their impact on an electric car's efficiency and optimize miles per kWh:

  • Preconditioning: Before setting off, precondition your car while it's still connected to the charger. This allows you to warm or cool the interior using electricity from the grid, preserving the battery's charge for driving.
  • Efficient Driving Habits: Practice efficient driving techniques like gentle acceleration, coasting, and avoiding abrupt braking. Smooth driving can significantly improve your electric car's efficiency.
  • Battery Management: Avoid letting the battery drain completely or charging it to 100% frequently. Keeping the battery within the 20-80% charge range is optimal for its longevity and performance.
  • Utilize Climate Control Wisely: Be mindful of how you use climate control. Precondition the car when connected to a charger and use seat heaters instead of heating the entire cabin to save energy.
  • Plan Your Routes: Consider weather conditions when planning your routes. If possible, choose routes with favourable weather conditions to maximize efficiency.
  • Regular Maintenance: Ensure your electric car is well-maintained. Regularly check and service your vehicle to optimize its performance and efficiency.


Weather conditions undeniably impact electric car efficiency, but understanding their effects and implementing smart driving habits and maintenance strategies can help mitigate these effects. By taking these steps, electric car owners can make the most of their vehicle's range and contribute to a more sustainable and eco-friendly future.
