How to Keep Your EV Safe and Efficient in Scorching Weather
Share this article:
As temperatures rise, electric vehicle (EV) owners face unique challenges in protecting their cars and maintaining performance. While EVs are known for their efficiency, extreme heat can strain the battery, reduce range, and even damage internal components if precautions aren't taken. Here’s a complete guide on how to keep your EV safe and running efficiently in scorching weather.
Park in the Shade or Indoors
Direct sunlight can significantly heat up your EV’s cabin and battery pack. Whenever possible, park your EV in a shaded area, under a carport, or inside a garage. This simple habit helps reduce battery stress and prevents cabin components from aging prematurely due to heat exposure.
Pre-Cool While Plugged In
Most EVs come with a pre-conditioning feature that lets you cool the cabin while the car is still charging. Use this smartly—cooling the interior while plugged in prevents battery drain once you're on the road, maintaining optimal range and keeping passengers comfortable from the start.
Monitor Battery Temperature
Excessive heat can degrade battery health over time. EVs are equipped with thermal management systems, but during heatwaves, it’s a good idea to avoid pushing your battery to the limits. Try not to charge to 100% unless necessary, and avoid deep discharges, especially in hot weather.
Limit Fast Charging in Extreme Heat
While fast charging is convenient, it generates extra heat, which can add stress to the battery—especially when ambient temperatures are already high. Opt for standard or slower charging methods during the hottest part of the day, or charge overnight when it's cooler.
Drive Efficiently
High heat can reduce your EV's range. Minimize aggressive acceleration and braking to optimize battery use. Use eco-driving modes, if available, and plan your trips to avoid unnecessary detours or extended idling in traffic under the sun.
Maintain Tire Pressure
Hot weather can cause tire pressure to rise, increasing the risk of a blowout and affecting handling and range. Check tire pressure regularly and adjust according to the manufacturer’s recommendations, especially before long drives in the heat.
Keep Software Updated
EV manufacturers often release software updates that improve thermal management and overall performance. Ensure your car’s firmware is up to date to benefit from the latest enhancements designed to improve performance during seasonal extremes.
Use Sunshades and Window Tinting
To reduce heat build-up inside the cabin, consider installing UV-reflective sunshades or legal window tints. This keeps the interior cooler, reduces the need for heavy A/C use, and protects your dashboard and upholstery from cracking or fading.
Inspect and Clean Cooling Systems
Some EVs have liquid-cooled battery systems that need periodic checks. Ensure coolant levels are adequate and the cooling system is functioning properly. Clean out any vents or grills that may be blocked by dust or debris.
Know Your Limits
In extremely hot conditions, consider delaying long trips or adjusting your driving schedule to early mornings or evenings. It not only saves energy but also protects both you and your vehicle from heat-related strain.
Hot weather doesn’t have to mean trouble for EV owners. With a few mindful steps, you can protect your electric vehicle from the effects of extreme heat and continue enjoying smooth, efficient, and eco-friendly driving all summer long.
