Most EV drivers know that cold weather can cause range loss in electric vehicles, and that running the heater can make the loss greater. But most drivers don’t consider the effect of hot weather. Extreme temperatures of any kind can have a detrimental effect on an EV, causing range loss, body wear and tear, and premature battery replacement.
According to CNBC, “lithium-ion batteries like the same sort of temperatures that we do” and perform best at a balmy 70 degrees. EVs lose power under 65 degrees, and lose it quickly under 50 degrees; however, temperatures in excess of 86 degrees also rob the vehicle of power. It’s no wonder EVs use 15% more power in the Upper Midwest and Southwest than on the California coast!
Not sure how to keep cool with your EV during the summer? Follow these simple tips to keep your car in peak performance during a heat wave.
1. Keep cool behind the wheel.
Sudden starts and stops are bad for any car, and particularly for EVs. Wear and tear on the vehicle increases when we drive too fast and then slam on the brakes, or make sudden movements, screech tires, or hit the gas too fast. Whether you have to skip a second cup of coffee, set your alarm five minutes earlier, or skip a route with road rage, avoiding the speed/brake cycle adds years to your car.
2. Take advantage of overnight charging.
One of the best steps you can take is installing a Level 2 home charger. The Blink HQ 200 is a perfect cost-effective option to charge your EV overnight during off-peak hours. Charging in the hot sun not only means you won’t get the best out of your battery, it’s also a drain on the power grid. With the Blink app, you can even schedule your home charging for off-peak hours when electricity is cheapest.

3. Leave your EV plugged in (at home).
When it’s plugged in, EVs benefit from thermal management systems that regulate battery temperature. The battery will be kept cool as long as it’s plugged in. But remember, if you're using public charging stations, good EV etiquette is to unplug so that others can charge. It will also help you avoid any occupancy fees charged at that location.
4. Watch where you park.
Running the heater and the air conditioner are the biggest drains on the battery. Many EVs can pre-cool/pre-condition the cabin and even feature cooling seats! Especially if your EV is still plugged into the charger, you can cool down the cabin before you're ready to drive away.
Sometimes we’re grateful for any parking spot at busy times, but try to find one in the shade, under a tree, or the shadow of a building or sign. Sun-blocking windshield covers or leaving a window cracked open can also reduce the cabin temperature on a sunny day. With practices like these, you can more quickly cool your EV and put less strain on your battery.
5. Avoid too many accessories.
The more accessories you’re using, the more power you’re losing. Keep it simple and focus on the road while driving. We all know focusing on texting while driving, using panel and touchscreen accessories, and even adjusting the radio, can be deadly. It can also drain your battery. On hot days, unplug unnecessary accessories and keep your eyes on the road.
6. Keep your vehicle charged at mid-range.
Lithium batteries are sensitive to extreme temperatures. Keep your charge below 85% to help the car run as efficiently as possible. This allows you to take advantage of regenerative braking!
7. Don’t bring everything with you.
If you know you’re going biking, skiing, or kayaking, it’s reasonable to bring the necessary equipment. However, increasing the weight of the vehicle also increases the drag, leading to lower battery efficiency. Take heavy items out of your car when they’re not necessary, and limit what you haul on each trip.
