The heating is a lot.
30-35% of range.
But the testing was not done well, and so there
are some caveats in that number. It will be that
bad, if you leave the car on flow-thru, and you
do short trips from one mall to another mall while
shopping. The short trips case causes the car to
warm up from the outside-low temperature to the
cabin-target-temperature, for each short trip. If
you do highway driving, with the car set to
recirculate instead of flow-thru, then the result
could differ. On a long trip, the wastage number
will be somewhat lower. We don't know the average power
needed to maintain the steady state cabin temp.

scientists interested in nuances.
The headlights are nothing, compared to the heat.
The incandescent on your ICE car, is replaced with
LEDs on the BEV. The incandescent would be 60W and 75W,
while the LEDs would be 8W and 10W or so to make the
same light. Small potatoes compared to 4300W for
cabin heat. *******
Here's a fun article for you. The driver was using a Bolt.
It shows there is an issue with charging from the lowest
level of charger, and that is, that the charger can't keep
the battery pack warmed to a good level for later. You would
be leaving the cable connected, just so the battery could
be kept at a good temperature.
For a person in a cold climate, it looks like you should be
a home owner and not an apartment dweller. As then you can
fit a charger worthy of winter conditions. Or alternately,
just drive your chariot into a heated garage. You can keep
your gas car out in the driveway or parked on the street.
Sensible electric car owners pick models with heated seats and heated
steering wheel as that is a small load and enables the heater to be used
A colleague who has a Tesla 3 makes use of the programmed heating whilst
on charge feature during the Winter. He has a 25mile commute so using
the heater on the way home is not an issue with a 300mile range car. But
as it is on charge overnight, he has it programmed to run the heater
whilst still connected. That means even though it is parked on his drive
over night, when he was ready to leave for work, it was already warm and
any ice had melted.
Last three cars have had heated seats. Don't like them, even the
current car with two heat seatings. The lowest still makes your arse
and back hot and sweaty and don't do anything for feet, knees or
hands. What do you have to do, wear long johns and gloves?
Much less wasteful than trying to heat up the whole car interior surely.
Heating something that one is in contact with is a very effective way
of using a small amount of heat. Motorcyclists use heated jackets and
there certainly isn't much spare electricity available on a 'bike.
The heater certainly hammers the battery on my PHEV but the trick is to
use the app to pre-heat while plugged-in, this warms the battery and the
car. Alternatively, ensure the ICE is running at the start of a trip and
then switch to electric when everything has warmed-up.
To use a quote from Sir Humphrey: buying a pure EV at the moment is a
"courageous decision" and it will be many years before I feel that

Not so. On a petrol car etc, they get up to heat very quickly - far
quicker than the coolant driven heater. And since they only heat your bum,
quite an efficient way of doing things.
mm0fmf used his keyboard to write :
I have a very efficient diesel, which needs lots of miles to get to
temperature, especially when it's cold. It is fitted with a diesel
burning 'night heater'. When it is really cold, I fire the heater up 20
minutes before setting off - engine and cabin are warmed, before I need
to get in to drive it.

My current car is the first I've had with them. Love them. Real boon until
the car heater gets going. Low setting doesn't make you sweaty. Full would
if you left it like that.
I love heated seats but would also like a heated steering wheel as my fingers take a long time to warm up but my present car has an app that allows me to preheat the interior and I rarely use the heated seats now.
There's more rubbish talked about electric cars and range. The simple way to use an electric car effectively is to keep topping up the battery when possible and not treated it like a petrol engine and run the tank low before refilling it. Also if embarking on a long journey research it first, establish the location of charging stations and plot the route accordingly around all high power charging stations and make allowance for any that may be occupied or not working. A good app will tell you this. The low power ones are useless unless you anticipate staying near one for a long period of time. I think the Tesla stations should be available to all even if they charge more for non Tesla cars Personally I have a BMW i3 rex which has a small motor bike engine which is used to recharge the battery when it gets too low and means as long as i can get to a petrol filling station I'm not going to be stuck and I could even carry a gallon of petrol if I was anal about it.
The article in yesterdays Guardian high lighted this. The problem there lay with the users lack of knowledge on using an electric vehicle.
