good evening y’all it’s been a while yes
as he things have been brewing for one today hi he drove to Madison Wisconsin
to pick up a picnic table that was sudden really good price on Facebook
marketplace so I am now super charging because my IDs my dad’s heavy freaking
trailer which is probably the heaviest one I’ve ever pulled with the Model S
and it’s freeway speeds of 75 miles an hour
I averaged about 580 to 600 watts watt hours per mile which is really high yes
really really high even my teardrop in my campers don’t go that high
so purpose for tonight’s video oh ho ho it’s a doozy let’s see what is going
what is going on well exciting news the model Y just started deliveries exciting
and there’s some two really important things I would like to touch on that are
featured in the model Y which are not featured in the s3x original roadster
probably gonna be featured in the 2020 roadster that 2019 point what are we
calling second general Chester okay so thing number one which is already
talked about quite a bit the model Y features a heat pump finally it took
long enough for them to get the heat pump what seat pump you might ask to put
it simply it’s a reverse air conditioner instead of an air conditioner which
takes the heat inside a space such as inside a car or a house and then
transfers that heat outside the school in your space a heat pump is a reverse
air-conditioner takes the heat from outside the space and moves it inside
the space and yes they do work in the winter what is so great about this well
they are very efficient very efficient you can
cut your winter power consumption significantly with a heat pump I’m gonna
link to some information on heat pumps in general there’s that too much dealing
with cars and heat pumps since really it’s only the electric vehicles and
maybe some fusses that use them RVs that use automotive style heat pumps because
they’re really not needed with a gas-powered vehicle since or diesel
since you have an endless supply of heat that you just want to get rid of which
you know heater but they’re very efficient give you an example I have a
little cottage that I rent out like it’s also in the description box below that’s
what I’ve been doing so busy doing is I’m trying to build a little more nest
egg Empire especially now that I have my baby Minah so I got three kids now all
my so give you an example might want my cottage that I rent out on Airbnb was
built in 1940s I believe was 1947 it has no natural gas service which in
Wisconsin would probably actually be the best choice if possible for heating an
entire house or cottage but it does have electric service and it’s always been
heated with baseboard electric well baseboard electric is 100 percent
efficient all the power going in gets turned into heat maybe there’s a little
line loss here there that because that’s lost as heat too so one to one ratio my
electric bill for that cottage is about 400 to 500 per month in the winter when
it was being powered with baseboard electric wasn’t even worth renting out
because I basically be renting it out just to keep it warm
no so I installed a 20 seer heat pump and this particular one it’s made by
chigo and I’ll link you guys to some heat pumps they’re really cheap
believe it or not if you’re willing to try and install them yourself which I
installed now ten of them and each one’s taking me about an hour and a half each
to install and five five to six hundred bucks each
heating the house now the car the cottage 100% with a heat pump it’s only
costing me about a hundred two hundred and twenty five dollars a month for the
entire electric bill and not just that is I keep it at 70 degrees Fahrenheit
all the time nice and comfortable for Wisconsin nights
that’s a tropical vacation or a tropical beach temperatures for us and with the
baseboards I’d have to turn them down as soon as the renters left those things
were crank down back down to 55 just enough to keep the pipes from freezing
no one’s in there not going to heat the place up to full full temperature so
that’s how much of a cost savings in terms of monetary wise and electricity
wise and I’m seeing heat pumps as high as 32 32 seer of course prices go
sky-high when they start getting that efficient but as just a rough example my
20 seer heat pump which actually is a for heating that’s for air conditioning
for heating it’s HS PF heating seasonal performance factor is actually like a 10
which is excellent for a heat pump on the heating end of things and that uses
about about 1200 watt continuous if it’s on max power to heat an entire 850
square foot house that was built in the 1940s with has insulation about as best
as I could get into the walls for the Aged house that it is so it is it’s an
old and drafty house basically the s3 and the ex use resistive heater which is
like a baseboard electric heat and I got to cut the shirt cuz I’m rambling on and
it’s one to one efficiency whereas the model Y with a heat pump you’re talking
about 300 to maybe 500 percent efficiency
pending on outside temperature the colder gets outside the less efficient
it’s going to get the warmer it is outside the more efficient it will be
also depending on how much they spent on the system you know whatever the H SPF
is on it which is gonna be great so in the winter time your main range
hit for driving is going to be heat heating the cabin so that is going to be
it’s basically it’s going to be the same power consumption in the wintertime
heating the cabin as it is in the summer time to cool it which for my model s the
actual air conditioning is very efficient and keeps me freezing even
especially at full power and and it works great and very low power
consumption the other thing I want to talk about is and doesn’t seem to take
too many people are actually talking and discussing this the mouth why has a
battery pack heater yay now the S and the X have battery pack heaters but for
some reason Tesla decided to get rid of that nice cheap little battery pack
heater that works so well and very proven and instead they got rid of that
and instead of use something like a the waste heat from the motors the motor or
motors and when you’re parked it puts the motors into a stall so that way they
generate heat without actually turning not a very efficient way of generating
Heat and it doesn’t also also does not generate very much heat and it’s very
slow to heat up that battery pack the amount of why they went back to the pack
heater awesome great here’s a case for why they really need it last year almost
exactly a year ago if he was around in the February March beginning of March
2019 Wisconsin hit a negative thirty-two degrees now we get cold occasionally but
we had that for two solid days well I pulled up to
a the Oak Creek Wisconsin supercharger after being after my battery was cold
soaked and within about 15 minutes I was at my full charge rate I got almost a
100% charge since I had to do some grocery shopping at that Meijer grocery
store that’s where the superchargers are located at perfect when I arrived there
there were other model threes plugged in you want know what their charge rate was
a big fat whopping zero and instead their range is going down not off
because it was trying to warm the pack somehow putting the motors in a stall
but that that stall mode generated so little heat they were not getting any
charge rate I take that back some of them the head started charging finally
by the time we were done grocery shopping an hour and like an hour and
twenty minutes later but they were only charging at like five or ten kilowatt or
as like I said I pulled in when I first plugged in I think I was
getting about five within 15 minutes my car was at about ninety eighty or ninety
kilowatt charge rate so that’s that’s the difference between having the pack
heater and not so those are two very exciting things that are going into the
model why and to be honest with you if if I could get grandfathered in from
limited free super charging and get the full self Drive Bob Loblaw you know kind
of match the features that are on my Model X I’d probably even if I had to do
it even up trade for the Model X to the amount of Y I’d probably do it but it’d
have to have the unlimited super charging towing and full self Drive
options for me because I can’t stand the damn Falcon wing doors on the Model X
yes they are event mad in the wintertime God they drive me batshit crazy all the
powered doors on the X just suck you know in the wintertime on a level that’s
so unbelievable but it seats seven full-grown adults so
that is all for tonight I rambled on for 11 minutes eight seconds so I actually
managed to restrain myself I figured I’d go to at least 15 or 20 minutes so more
to come hopefully someone around Wisconsin takes
delivery of one soon so I can get my hands I’m going to do a little videos
and testing

    So might Y heat the battery even for normal driving? Could it get the 400V from one module and use the heat more locally? Some clever switching might pull 50-100 kW from each of 4 modules. One is plenty for most drives. Balancing to happen only when charging.
    Crazy idea, sure.

    I hope that Tesla will add heat pumps to their other vehicles.

    But….the Y is missing something too…besides no towing (yet)…no parcel shelf or cargo cover of any kind.

    I have a feeling that they may be fitting the same heat pump system in the new 3. My week old car (ordered last August, long story) is getting 85% rated range in Irish winter weather, freezing mornings even short trips.

    Andy Slye just had video about heat pump in model Y, but you went an extra mile(battery hester), and with your knowledge about heat pump and differences in other Tesla heating experiences, it's a bomb of information! Thanks so much!

    Different explanation of a heat pump:

    It's a pump, that pumps heat. In whatever direction you (car) please.

    You put in work (electricity) and you get heat. Super advantage is that you can get more heat energy than you put into a pump.

    You don't 'create' the heat, you just transport it from a place the heat already is. It's possible (and usually THE purpose) to transport heat from colder place to warmer place by making the colder place even colder. But because the colder place usually has practically infinite amount of heat at disposal, you never make it colder (You cannot make the whole atmosphere colder by making car interior warmer. Also the heat eventually disspipates again.)
