we are currently at one of my favorite
Chinese most stations charging any
whopping about 32 kilowatt right now
putting some power into an ice-cold
battery was cold i thought my life and
I've hinted to it before but I got a new
little device here and can see flashes
great here and can meet little little
thing here and turn on some night-vision
shaft we and still not enough but what
it is
ICF this neat little dongle here thanks
to some very awesome Tesla Motors club
members and this converts the can bus to
obd reader to reader and that's a
low-power Bluetooth transmitter which
then transmits up here to my phone using
a certainly closed but available Tesla
spite app now of this is intestines by
this remote us because I just wanted to
see what checking out of 33 kill a lot
right now and that's because the voltage
of the battery so alone so as you can
see we're just kinda but no way here so
we are going to open up Tesla spy until
we have lots of data goodies and as you
can see it shows some interesting data
that you don't normally get to see about
your car one of those being in the most
important is the berry patch health for
the most part if you look at the top it
starts off with my vin number which they
do a great those are in annual ease
man shows that the voltage of the pack
mouth usually you get to see the pack
voltage if you're supercharging well
this lets me see the voltage of the pack
1 i'm not super charity you can see the
negative 95.3 amp the negative means
powers going into the battery if there
wasn't a negative on it then we'll be
drawing power from the battery now this
is one thing I'm not too sure on what
you see where it says pack it's an
80-point name and then remaining 16.6
now what I'm not sure of yet and i'm
still experimenting on this is does that
18.9 with a 16.6 now 16.7 kilowatt hour
remaining is that before are the actual
pet capacity or is that the pack
capacity after after the Tesla chops the
little little bit of overhead for entire
Benny
yes it's been awhile since i don't have
any of any talker in the car interment
you can go back to your seat
so one way I'm going to be able to find
that out I've asked you a few times I
haven't got any responses from anybody
as to this yet but the last test
actually my other my bluetooth on don't
had crapped out on me i was a deal
it worked for about a day so I said that
was back when I just got the new one
back then you're not yesterday so
finally get to test it now
now the other one read last week 81.1
kilowatt hour battery pack capacity now
that would go ahead and hand with my
current rated range of about 280 miles
which would show the loss of capacity so
it also would would go hand-in-hand with
what the usable
capacity of the battery pack according
to jason hughes who act the BMS and got
pulled some actual number of street from
the DNS system now you should also see
them my the mileage on the car also see
the discharge in charge numbers there
which are supposed to be the lifetime
charge and discharge of the vehicle now
I don't know that for the whole vehicle
even if you have a battery change or if
that's reported by the berry pack so the
life of a battery pack personally the
numbers don't quite add up my Kaminsky
kidding
Koski exciting to me so I mean discharge
should actually technically be lower
than charge because you know you do get
self discharge of a battery pack so i
don't know if those numbers are reversed
but says charge 11 or discharged so at
12.8 68 megawatts so if we go down to
the screen here and go to my trips trip
a-and this car is the lifetime
consumption of the vehicle so since i
got it
this is what about 40 miles from the car
i think that is 9.81 megawatts so who I
mean we've got a three megawatt
different that's a pretty big difference
so i'm not sure exactly how accurate
that is now we get to the good stuff
alright this represents the 96 bricks in
my battery pack so how the car is
arranged there's something 7200 and
something 18 650 look himself in my car
each of those cells is placed into a
brick then there's multiple bricks for
sheet there's 16 sheets of cells in the
car 16 modules of you if you will so
what this shows me is what the voltage
of each individual r96 bricks of cells
because each brick has a nominal voltage
of about 3.7 fully charged is about 4.2
volts when you add up all the bricks
together and come out to about 403 bolts
roughly which is what the car reports is
fully charged when you're done charging
and a supercharger so this shows us what
each of those bricks held that against
each of them are right now I have a 17
millivolt difference between the lowest
and the highest brick the lowest
brickhead as 3.6 48 volts iceberg is 3.6
64 with an average of three point six 57
very interesting and it's actually a
little more often it is when it's at
rest so you can see it's slightly
different for to the bricks little wavy
haven't quite figured everything out but
this is the first time I've been able to
see it
well it's been doing a DC fast charge of
some sort that if we hopes your mouth a
little bit
can he meant not sure what you need your
feelings receiving more elsewhere
tonight mode means that your shoes off
our film right now my state of charge is
24.99 25-percent quickly jumped and see
what I'm charging it then 34 kilowatt ok
so now I right now until I'm still
exploring the problem i'm quite a bit
now that I got the dongle back at you
can be continued to explore again but so
far there's basically three usable
screens for me at the moment this one
gives me the voltage histogram gives it
a little bit better idea of the balance
of the pack so this is showing that
there is a 16 millivolts difference how
of course with them in the minimum
average and maximum and after you know
in the morning after it's been sitting
in charge complete dependent no matter
what you know that the the charge rate
that i have selected is it's usually
about a five or six millivolt difference
meaning my pack is really really
balanced so it's quite possible that i'm
going to have to rewrite the book and
I'm balancing the test the battery pack
by doing one hundred percent charges so
keep that in mind I mean I wrote the
book i'm balancing your battery pack at
superchargers and that mean don't get me
wrong it's working but the theory behind
it might need to change we had
twenty-six percent car is now reporting
that we have a rated range of 62
yeah 62 miles still load fifteen
available
let's let's switch screens when we
return we'll come back and here is my
battery pack temperature before we
started our drive to get here we have a
few different areas different now we're
at about 24 degrees Fahrenheit of our
battery pack now we're at 66 degrees
Fahrenheit for the hottest self
excuse me the hottest module now there
appears to be two temperature sensors
per module and so a total of thirty-two
32 sensors for these 16 modulation in my
90 degrees now one thing that's a little
strange is this one always seems to
report quite a bit hotter than the
others
I we're not talking that bigger
difference regarding 67 degrees compared
to about 63.2 so that the difference
isn't as big as what the chart makes it
look like but we're still talking that
will say 65 so talking about how 2.2
degrees hotter than their other sensors
so i don't know i guess in a way that
might be a good thing in the summertime
because then the car might trigger the
active cooling sooner but no winter time
it might let it charge the batteries are
still well actually no it should be just
fine because know what time will let you
charge until to call the cell is up to
the designated temperature for charging
so like I say this is still a work in
progress on going on going still
learning that is a few screens and
there's lots of different actions i
haven't even started to touch yet so
there's a lot of good information that i
will be adding to my every thousand mile
range updates on his feet
um I just hit the 26,000 last weekend
and we have hit shoot any 'hi he's
taking these children our Mama's left
got your foot teeth said mama Jimmy then
season-high five cents here he funny
little man
so we'll be adding that to do my range
updates and jumped up and now back to 15
millivolt I can't wait to see what this
looks like when we plug into the
supercharger on friday night I mean that
should be something something fairly
impressive now have 68 moderated miles
into the car let's see what we're
charging at no I'm curious on how high
the voltages will jump up when the cars
charging at 98 kilowatt since that seems
to be the maximum i can pepper since
they came out with firmware 833 kill
have our excuse me kilowatt surgery it's
not too good i should be able to hit
about 44 on this stations and 400 nissan
Slim's i don't know if i'm getting i'm
either getting voltage limited right now
or temperature limited have returned at
94 amp think the station goes up 220m so
I think I'm temperature limited yet but
I really shouldn't be and well above be
there and well about the the temperature
reading for supercharging 70.2 66 point
for that one just keeps going up to you
so that's the in my introduction to
Tesla spy you will not see that in the
app store I that's currently only
available on test flight but you're
welcome to check out the form link in
the Tesla Motors club forum just search
for p.m. dish spy
I'm there's it's available for Android
and iOS and alive discovered discussions
going on right now about it so we're
going to stick around till we have a
hundred miles an hour battery pack and
then we're going to continue the drive
home tonight folks smile tease
