Battery Preheating in Winter: Set the Right Temperature

Cold batteries are sluggish. Preheating your EV before a winter drive improves efficiency, protects range and makes the cabin comfortable. Here's how it works and how to use it.

On a cold morning, your EV's battery behaves differently until it warms up. The good news: you don't have to manage any of this manually — the car handles the warming, and you just set the schedule — a one-time job that pays off all winter. Battery preheating means warming the battery to a better operating temperature before or during a drive. It's one of the smartest winter features you can use. Here's what it does and how to get the most from it.

Why preheating matters

The battery's chemistry works best within a temperature range. In cold weather, reaction rates slow down and the battery can't deliver power as freely. Preheating raises the battery's temperature so it can work efficiently from the moment you drive. That means better performance and less energy spent warming the pack during the trip.

Think of it this way: warm the battery before you set off, and the heating energy comes from the charger. It never touches your driving range.

Precondition while plugged in

The most efficient way to preheat is while the car is still connected to a charger. Aim to start it shortly before you leave — the car does the rest, warming the battery and cabin together. There's no need to leave it running for hours. If you have a home charger, use the XPENG app to precondition the car before you leave. Or schedule it so the car is ready when you are. Because the car is plugged in, the battery and cabin can warm up without reducing your available range. This is the single best winter habit for range. The same trick works before fast charging: preheat the battery on the way to a fast charger, and charging speeds stay closer to normal. Cold batteries accept power more slowly, so a warm pack saves time at the station.

Set the cabin temperature sensibly

For everyday winter driving, set the climate control to around 22°C and use recirculation mode. It keeps the cabin comfortable without making the heater work harder than it needs to. Avoid cranking the temperature to maximum on a short trip — the extra heat costs range without adding much comfort. In an Australian winter, that 22°C setting is plenty for most mornings — reserve maximum heat for genuinely cold starts in the mountains.

Choose an efficient drive mode

Once you're on the road, an efficient drive mode with high energy recovery smooths acceleration and braking. It also helps the battery hold its temperature longer, which matters on longer drives. Avoiding sudden acceleration and heavy braking matters more in winter, when the battery is less responsive in the cold.

Comfort without the range penalty

Preheating also makes the cabin comfortable faster. And because the battery is already warm, the first kilometres of your drive are more efficient. You protect range before you've even left the driveway. On a cold morning, you step into a warm car instead of waiting for the heater to catch up. It's the difference between starting a winter drive comfortably and shivering through the first few kilometres. If your commute starts before sunrise, set the schedule up once. After that, the car is simply ready when you walk out the door.

The bottom line

Battery preheating is simple: plug in, precondition, and drive off with a warm battery and a comfortable cabin. It's one of the easiest winter habits to build — and that's why preheating an EV battery tops so many winter checklists. It's one of the easiest ways to protect the winter range — and it makes winter mornings genuinely nicer.
