12V electric blanket will not hurt my 12V battery if I only use it while driving, right?

[music_cities]

All this talk about draining the 12V battery has me worried. Just to confirm: if I’m actually driving the car, I have lots of 12V capacity, right? So, I can heat the passengers with a 12V blanket and turn down the cabin temperature a little?

There’s a nice little -30°C spell coming in on Thursday/Friday and I want to be ready for it!

As long as the amperage of the blanket doesn't exceed the max allowed in the outlet, you are fine. The HV battery will charge the 12v battery while driving.

Yes. There is no issue using the 12V power ports, just make the blanket doesn't draw more than 15 amps.

That's useful information.

I have a new 12V blanket and it keeps my knees so beautifully warm.

What a car.... need an electric blanket to keep warm because if you use e-heat it'll kill your range!

Did that in 32F weather, I was losing 1% battery a mile and wasn't going to make it home, had to turn off e-heat.

I wonder how many people go through the first winter in their first EV and it sours them. And don't give me should have researched it, there was nothing telling me about winter range when I purchased in the spring just here's the EPA range which will depend on speed, hills, temperature etc.. yeah, massively depends on temperature!

And all the online motoring journalist reviews didn't mention winter.

I don’t need an electric blanket for range on the drives I’m doing. But, man, I sure wish someone had told me about electric blankets in cars 30 years ago. All those years freezing in the cabin waiting for the ice engine to heat up. I could have avoided those days if someone had only told me.

You are correct to some degree but there is such a thing as common sense. If a car only has an electric heater then the more you run the heat the quicker it will drain the battery. I think most people (I think) realize that if their cell phone is too bright it drains the battery faster. Same effect.

No one is driving around with an electric blanket covering their legs, right?

That seems very dangerous.

I don't see it as an issue for passengers but I would not want to live somewhere where it was even a consideration.

About the same as a person driving with a large heavy wool skirt covering their legs.

The skirt is anchored at the waist. A blanket is free to fall to the floor and block the brake pedal.

I’ve had great success with a 12V blanket for my young daughter. I never go above the lowest setting and it keeps her plenty warm.

Good thinking I’ll see if I can anchor it on my belt. Or maybe loop it under the shoulder belt n

You will be just fine with an electric blanket designed for the 12v socket. The vehicle keeps the 12v powered up via its high voltage to low voktage DC to DC converter when the vehicle is running. If you forget it plugged in when you turn off the vehicle, the 12v socket turns off after a few min and it should not drain the battery much.

I purchased these car seat warmers along with a 12v socket extension cable for the rear seats of my Mach-e, and the kids love it. Keeps them toasty warm in the back seats! Honestly this should have been standard equipment in the Premium, and I'm a bit annoyed that I had to buy an aftermarket solution, but it works just as well.

If your electric blanket draws more than 15 amps you might glow in the dark after using it.
