Extreme Heat Drains EV Range: How 35°C Weather Hurts Electric Car Performance.

Summer Heat and Its Impact on Vehicle Efficiency

According to Novyny.live: Research by the American Automobile Association reveals that scorching summer temperatures negatively affect the performance of cars, including electric vehicles, hybrids, and those with internal combustion engines. At 35°C, the strain on key vehicle components increases, leading to reduced efficiency.

For electric cars, hot weather cuts efficiency by 10.4% compared to 24°C conditions. This translates to an 8.5% reduction in driving range per full battery charge. Additionally, resource consumption rises every 1,600 kilometers driven in summer, potentially raising overall operating costs.

How High Temperatures Challenge Batteries

Lithium iron phosphate batteries, often considered stable in high heat, also face difficulties. The EV’s onboard computer uses significant energy to cool the battery pack, further lowering efficiency in hot climates.

Given these factors, drivers are advised to pay close attention to how they use their vehicles during summer heatwaves. This awareness can help prevent performance issues and conserve resources.

These study results highlight the importance of considering weather conditions when operating vehicles, especially electric cars, which already experience performance changes due to high temperatures.

Drivers can take steps to reduce the negative effects of heat, for example:

• planning trips during cooler times of the day;
• ensuring proper battery cooling.

Such measures can be crucial for maintaining efficiency and saving on vehicle operating costs during hot periods.
