Heading into the first winter with an EV I have been looking around for hints and tips.
The one I am confused on is to do with pre heating the battery.
For home charging do I need to pre heat battery before charging.
Should I pre heat battery before setting off on long journey?
Or does it not matter?
Ive seen that you pre heat cabin before setting off.
Any other tipa

What car have you got?
You will want to preheat the battery and/or car before departing from home. This means you lose less energy on the road after setting off, your car should draw from the charger rather than the battery to do this.
You don't need to preheat the battery before charging at home, but you may be able to preheat the battery before rapid charging on long journeys.
Lower battery temperatures will reduce rate of charge on rapids. Some cars you set the charger as a destination and it precondition for you. Some cars require some accel and decel harshly to drive the battery temps.

Pre heating battery for rapid charging I get.
Was not sure if pre heating battery before setting off would improve range.
The BMW i3 preheats the battery if you set a departure time well in advance, if it is below 10 centigrade, and if it is connected to a charger. It gives a little buzz at the start of the charging window and another one just before departure. The whole process is automatic. The Tesla model 3 does something automatically on a home charger as well but I don't know the logic. Other makes and models will differ.

It does improve range a bit (10 miles in my iPace) but I rarely need full range so don't bother. Depends on the car but to properly precondition the battery most need to be plugged in (obviously) to a proper home charger, not a 3 pin granny charger, and be fully charged a few (4 in my case) hours before set departure time.

Most people just precondition the cabin 20 mins before departure, but this has no effect on battery temps.
Preheating is nice, you get into a nice warm defrosted car.
If you're doing a long journey, it will extend the range, meaning any use of expensive public charging is reduced.
If you're doing a short journey, and the car is plugged into power, it just means that you are heating the car on power at whatever your current mains rate is - which might be more than the rate when you normally charge it.

The main benefit seems to be doing this pre-journey stuff while connected to your home charger. Ideally some sort of aircraft carrier catapult thing would be handy to relieve the car of the energy drain of getting up to speed. Though for convenience it may require each house to have its own slip road.
Going into winter the most alarming thing is that your access to actual data in an EV is far superior to most ICE cars. So while ICE also uses more gas in colder weather and all cars experience more drag in heavy rain etc., in an ICE car it isn't in your face. You just fill up a bit more frequently yet in an EV you can sit there and look at it and the impacts are significant.

An old workplace of mine was downhill for nearly 10 miles. Was quite normal to do a third of my commute and still have the same range I left the office with (having charged at work too, because PHEV)..

Thanks for the replies.
I'll just make sure to have a toasty car then before departure.
Putting the bum warmers is not an option on the VW app which is irritating.
Yeah, it’s weird that. You can do the rear screen and mirrors but not the seats. The Born allows you to do the seats. It’s like VW and Cupra employed two comepltely different teams for the app development for the cars despite being on the common platform…I'll just make sure to have a toasty car then before departure.

I m surprised people are talking about 20 mins to warm the cabin. My Model Y takes less than 5 mins. Maybe a few mins longer if it s sub zero permafrost conditions.
Quite fancied the idea of pre-heating before we got the car but don't bother now that we have it. Get in, heating on at 22°, heated seats and steering wheel on. By the time I've reversed out of the garage the car (2022 Kona) is fairly warm, by the end of the street it's perfectly comfortable - my wife loves it. Recently back from Glencoe in 0-4° weather. Charged to 100% gave an estimated 318 miles. Heating on at 22° reduced this to 308m - although this was based on previous warmer conditions. Actual total range calculated after arrival (148m trip) was 288m.
As an aside, I was very surprised at the number of slow moving vehicles this time, especially those happy to form a queue and ignore long clear overtaking opportunities, lost count of the overtakes.

Don't have an ID.3 but seen that discussed on SpeakEV where some owners said they didn't work and turns out it should work on all versions of the car and App. Something about selecting the zone (left /right) of the car and it worked the opposite way around on early versions?I'll just make sure to have a toasty car then before departure.
