# Temps, Precondition, Regen data with GRAPHS

Go ahead and comment, doesn't matter.

The comments are really the best part. Especially when someone tries to make the analogy that 48kW instantaneous power not used to move the vehicle, can be extrapolated from energy used over a distance. Talk about "data masters interpretations"!

Yeah, he has revised down his claim though. He went down to about 20kW, then ~15kW. It's almost as though there is some variable that is being missed that is causing those wild swings...maybe it is varying SPEEDS!

15kW is still too high, twice the current programmed max capable on an AWD vehicle(~7.5kW)...at a standstill.

Its almost as though when you make an absurd lie, you are willing to adjust your numbers to appeal to the crowd who is listening until they think it sounds reasonable.

...though I think the real limiting factor is the rate of heat transfer between the motor and coolant, and or heat transfer between coolant and battery.

I did notice this morning that the Motor and coolant had a hard time maintaining temperature while driving in ~0C weather. Motor got up to ~32C but would drop 1-2C during slowdowns/stops. And the coolant temp at the battery inlet sensor did not want to go up too much compared to when I started driving.

Too bad he still uses the same energy app graph for all three claims that are from at least 2 different trips.

Someone who does zero math to explain something can only maintain the lie until the crowd listening either does not believe what is being said, or until someone actually proves it wrong with math. The latter results in less comments and typically causes him to flee.

“Yeah, he has revised down his claim though. He went down to about 20kW, then ~15kW.”

The last one was nearly 30kW, and he suggested PC gobbled up twice the energy as everything else the car does, including a 14 minute drive.

Anyone can make the claim their car uses X amount of energy by sitting in one spot without moving for an unknown amount of time running the cabin heater at maximum, so that their 'Past 15 miles' graph shows "off the charts" wh/mi.

@andy
This is why a lot of service centers get accused of Ferris Bueller type antics. People don't have a clue about how you get poor efficiency spikes from sitting still.

“ so that their 'Past 15 miles' graph shows "off the charts" wh/mi.”

But remember, EV range is universally expressed in Wh/mi, so being off the charts is a wonderful thing.

Any ideas what is being used? Glycol? PAO?

I presume it's still ethylene glycol

Now don't keep beating up on poor @Bighorn on his "48kW" clanger. He just miscalculated the data.

You misspelled “correctly calculated the data erroneously collected.”

Nope no miscalculation by Bighorn...

FISHEV Oct 20, 2019 in his OP "Battery Pre-conditioning uses how much power?"
"The Preconditioning message was on for the 11 mile, 10 minute trip. Taking out the 11 miles for the trip, the Pre-Conditioning looks to have used 34 miles of range, 8kWh of
power."

8kWh in 10 minutes = 48kW power draw.

@MAB1980: I think you can look up the coolant in the parts catalog. I know it was spec'd somewhere I just can't remember where right now.

Glad you admitted the "48kW" was not my number but someone else's.

Sorry all the "data" interpretation from the boys furious calcs don't match the actual car performance owner's see but in fairness, they are flying blind trying to reverse engineer what the car is doing from raw numbers without knowing how it is integrated in the car.

The calc's are easy.

Car used 43 miles of range to go 10 miles with Preconditioning on. If @Bighorn's calcs don't match the car, I'm going with the car.

What do you think the draw was then?
• edited January 18
And you are right the 48kW number wasn't yours, it was MATH that determined the value based on YOUR bad data.

"Car used 43 miles of range to go 10 miles with Preconditioning on." "10 minute trip""

As you saw from the Start and Finish energy graphs, it used 43 miles of range for 10 miles. Just a fact. That YOU can't explain it doesn't change the facts. Facts EVERY Model 3 owner will see in similar conditions, battery 38F and heading to SC 10 miles away.

If you look at the energy graphs you were provided, you can see the huge spike. The car uses miles not time on the Energy Graph. The spikes are literally off the chart in energy use, something your "numbers" claim is "impossible" but there it is on the car's Energy graph.

Looking at trends, the Preconditioning seems to turn on about 10-20 miles out from SC's. In all the graphs. You should probably look at what the car is actually doing vs. looking at the raw data and misinterpreting it.

Hey I am just saying that YOUR numbers calculate out to a 48kW power draw over the 10 minutes. If you split that between both motors that is 24kW per motor just for heating. That is not even in the realm of possibility.

And then you come up with two other scenarios that provide wildly different answers that you can't explain.

But thanks for allowing me to point out the flaw in your statements in another thread for everyone to see.
