Intentional cold soak -15

[TaxmanHog]

The battery prep phase resumed at 9:27, automatic cabin conditioning did not execute as expected at 9:45, I started it by hitting the fan button, also requested extra time to 10:15 though I plan to get out around 10:00 ish.

Here is the final results of charging & conditioning:

Fordpass doesn't track total kWh accurately IF you interrupt the process with stop/start button

Now to see how far this lasts on my 160 ish mile trip today

Very well documented thanks! Be watching the see how the trip went. If round trip and below freezing but above 0* my guess is 50 miles of range at 15% on return.

Full rate ~9 KW battery warming kicked on around 12:02 pm, ran for about 12 minutes then amperage went up to ~18 KW as if the battery OBCC was trying to top the battery, but note SOC only went up 0% during the entire process of 1.75 hours. Total energy used to condition the battery was 10.1 kWh. The official cabin conditioning ran from 12:45 to 1:00 pm, you see the cycling of the PTC around and under 4.5 KW during this phase, it appears the battery was at spec around 12:35.

I have an Emporia Vue Gen 2 with current transformers on the two 100A lines going to the garage sub-panel with Tesla J1772 wall connector, etc. Is there a way to see the two lines added together as 240V instead of two separate 120V Amp/kWh rates?

Now to see how far this lasts on my 160 ish mile trip today

Condition at the start of the trip with warm battery & cabin, 100% SOC and 100% power to the motors, possible range is 263 as I'm rolling away from the house, note the immediate drop from the 309 while it was plugged in from my morning report, I think the route planner and current condition reduced the projected value since I would be getting onto the highway a short distance away. Ideal {309/131=2.36 MPK} while more realistic {263/131=2.01 MPK}

Road trip completed, from the house to the "Club House" and back home ~168 miles, overall 1.8 MPK, using 74% of the 131 KWH battery or 97 kWh, the computed MPK is 1.73.

Cabin temps maintained at 72° while outside temps ranged from low 30's to 27° seen below.

The ride was at a steady 66 MPH while on the highway, including gusty winds.

Notice the gauge cluster and the where did my energy go MPK values match!!!!

I noticed this on the way up earlier, you can still get it to mis-match by 0.1, especially if goosing the go pedal too much, I was easy going the whole trip except for a couple quick down hill passes to get by unsafe slow-pokes. I don't know when this improvement came about, see my SIG for most recent OTA's

The battery lost a little of its optimism, after the first leg of the ride was done, this was my estimated range and SOC. I consumed 36% or ~ 47 kWh for a 1.79 MPK, as the evening got cooler the start of the return trip home, the available energy to the motors was limited 97% which slowly crept lower to the end of the trip.

I did not require any charging, but I did set a destination for a DCFC not far from my house to simulate on the fly battery preparation in case I needed to stop, the battery temp gauge stayed at the normal mid point the whole day so I suspect not to much warming was needed.

I only look at WATTS or CURRENCY displays and ignore all the others.

I'm using the two large clamps, one on each of the split phase feeds to the EVSE.

If I look at the amperage display the value is double the actual current.

Hah, she was projecting 48 mile at 26%, the orange (ALERT) warning at 50 miles came on at 27%, this is a little pessimistic, 26% at my 1.8 burn rate should get me 61 miles to the last electron, I'm not pushing it that close this time of year.

No complaints here just curious if the motors temperature gauge is just a dummy gauge. Or possibly only registers overheating. I started up this morning and the motor is right on the line (always is -15 to 95) yet I didn’t lose a single percent of battery overnight so how is it at temp?

by the way, the only reason this was intentional is I would’ve had to move my wife’s car to charge and seeing I was almost at 90 didn’t bother

Your GOM sure took a hit. Fuck! So far here in Michigan charging to 90% even with it 6 this morning granted I was plugged in I was showing around 265ish. I have a 23 lariat ER.
