If you’ve been sweating it out in your EV lately, you’re not alone. With temperatures hitting 90 degrees and up around the US, it’s natural to wonder:
Is blasting the A/C going to wreck my range?
Should I crack the window instead?
How different is EV heat management compared to gas cars?
Let’s break it down.
Key Considerations When Driving Your EV in the Heat
- 1. Climate control eats range — but not as much as you’d think
Unlike ICE (Internal Combustion Engine) cars, EVs don’t “waste” engine heat for cabin comfort. Instead, they draw from your battery. (Womp womp) Turning the A/C on will reduce range, but usually only by 5–10%, especially in modern EVs with efficient systems. - 2. Heat pumps help a LOT
If your EV has a heat pump (like many Teslas, Hyundai Ioniq 5, or some VW ID.4 trims), it uses ambient air more efficiently. That means less battery drain to cool you down. - 3. Pre-conditioning is your friend
You can cool the car while it’s plugged in so it doesn’t zap your range once you unplug. Use your app or scheduled departure feature when possible. - 4. EV batteries hate extreme heat
High temps can accelerate long-term battery degradation — not instantly, but over time. Park in the shade, use a sunshade, and avoid deep fast charges if your battery is already scorching. - 5. Cabin temp doesn’t match engine temp
Since EVs don’t have a traditional engine, heat buildup is more gradual. You might not feel it right away, but battery temps can spike during long drives or DC fast charging.
❄️ Pro Tip:
Cracking the window can help a little, but don’t suffer. Your comfort matters, and today’s EVs are designed to manage temperature efficiently. Just be mindful of your range if you’re far from a charger.
How EVs Differ From ICE/Hybrids in the Heat:
| Feature | EV | ICE/Hybrid |
| Cabin A/C Source | Battery-powered | Engine heat + A/C compressor |
| Idle Cooling | Silent, efficient | Requires engine running |
| Pre-cooling while plugged in | Yes | No or limited |
| Waste heat availability | Minimal | High (engine) |
| Battery heat sensitivity | High | Lower |
Bottom line: Hot weather has SOME effect on EVs, but it’s totally manageable with a little awareness. Use your tech, precondition when you can, and stay cool — literally and figuratively.
