How much difference in range is there between a P85D or 85D to a 75D?
From
electrek.co
Original 60 – ~61 kWh total capacity, ~58.5 kWh usable.
Original 70 – ~71.2 kWh total capacity, 68.8 kWh usable
75/75D – 75 kWh total capacity, 72.6 kWh usable
Software limited 60/60D – 62.4 kWh usable
Software limited 70/70D – 65.9 kWh usable
85/P85/85D/P85D – ~81.5 kWh total capacity, ~77.5 kWh usable
90D/P90D – ~85.8 kWh total capacity, 81.8 kWh usable
and from
link re: 100 battery: "
the BMS indicates 98.4 kWh of usable capacity"
so on that basis the 85 battery has 10% more usable battery than the 75. Different battery chemistry, but I don't think that will make a difference?.
non-P(D) to P(D) is quoted at about 10% range reduction I think.
Although looking at Tesla website Car Designer:
NEDC range (unrealistic, but perhaps?? suitable for model-comparison) 75D=304 100D=393 P100DL=381
So 75D - 100D is NEDC Range difference +29%, usable battery difference is 36% ... so maybe not useful for comparison!
P100DL 381 miles : 100D 393 miles = 3%. I think the real world difference is more than that, but that's just my subjective view ... People did not buy the initial P100D and waiting for the 100D because they wanted Max Range. Can't believe they would have done that for just 3% ...
so I can use it for a working day to test range in the real world
Hardest part of that test will be NOT driving it like you stole it! Maybe you can ... ermmm ... do "that part of the test" at the start of the test (before charging) or after re-charging on second day
If you are trying for max reasonable day-to-day range, and assuming you are speed limited a good proportion of the time by commuter traffic then its good that we are in "Winter" and have low temperatures, so a reasonably-worst-case scenario
I suggest you try to use minimum energy, and as such turn on Range Mode and also try to use Climate as little as possible Turn the seat heater on (uses much less power than cabin air heater). Perhaps wear a woolly hat.I appreciate that you wouldn't drive like that normally, but if you do your test like that and it doesn't have the range then for certain you're not going to be able to squeeze any more out of it ...
Plug the car in (13 AMP socket will do as presumably that will be all you have at home) and pre-heat it for at least 30 minutes before you leave. When you own the car, and it is plugged in overnight, you can schedule heating to happen whilst you are still asleep
Actually if the car is reasonably charged when you get home then charging it on 13AMP will probably charge it to 100% overnight. normally it would be set to, say, Charge Limit = 90% so if you want to start with 100% charge then you'll need to change the Slider Config to 100%
13AMP will charge at about 5 MPH.
No need to do that if your Test Day is not a max-range day, but just a "decent range try-out" test.
There are two TRIP counters, so you might want to reset both of those at the start, and then you could use one for whole-day and the second for individual journey. If you are visiting clients then getting-there is likely to be one figure, and short-journey-between clients something else.
Apologies if this all Granny + Eggs, just keen that your only-one-day test goes as well as it can.
