Actual Charging Speeds at Home (What are you getting?)

[Jernat]

I charged my Lightning with my Grizzl-e from 70% to 90% in 2hrs 20 min. Assuming 10% loss, I calculated 8.64KW per hour. I did verify my dip switch settings from factory were correct at 40Amps.

I’ve got a grizzl-e on a 50amp circuit as well and my e-tron actually displays the kW going into the battery (what a novel concept). I typically see 8.8kW so your estimate is pretty good!

Basically I either need to let it go or buy a charger that shows real time electricity transfer. Which I really don’t need considering I have solar and battery back up and could never use a full charge in a day, lol.

I'm surprised that with solar and battery backup you can't better isolate usage on your end and see.

My utility company has an app that shows me usage, down to exact points in time. It's 24 hours delayed, but if I pay $1.99 a month I can get it immediate. So I took the 6 month free trial for the immediate, and got readings on every major appliance to see what they were.

First picture is my usage 2 days ago. You can clearly see that the charger kicked on at 7PM. Second picture shows that at 7:37PM I was using 6,416 watts. I can see that after I was using 764 watts. 6,416 - 764 = 5,652. But it wasn't on for the full hour, and the app is only showing one hour increments. If I go back to when it charged for multiple hours (late October), I see 8,392, 8,414, 8,421, then 532 the next hour. so 8,400 - 530 = 7,870.

My charger is set at 32 amps, and I have 248 volts. 7,936 watts. Pretty close.

My 120v wall outlet gives me about 2 miles an hr off the ford mobile charger. With a 20 mile commute, it's good enough for me to use the 6kw Chargers at work.

(I'm pretty sure 5kwh though is not 36 miles lol)

The only thing I care about is that my target charge % is reached by morning. Which it always is.
8, 9, 11 KW……meh, who cares?

I have the emporia charger and see 46a. It’s hardwired on a 60a circuit.

Same charger - hardwired to a 60A circuit and it's at 11.0kW (46A) sustained charging.

Always charge to 100% once a week.

4 hours total charge time on a weekend:

I have the grizzl e and it charges at around 20 miles an hour in 40-55 degree weather. I know as said above that’s not scientific but that’s all I have are the ford app to go off

Back story, after doing yesterdays Thanksgiving ride to & from family in Nashua NH, I stopped for a DCFC for 39 minutes, [22% to 80%] or 58% gained, that was 240 miles an hour, and EA app said I took on 79 kwh for $10 even including sales tax. A substantial savings to use EA in minute based charging regions like Massachusetts, which is why I stopped to DCFC.

Then we drove the last 10 miles to the house , the SOC went from 80 to 77, plugged into the FCSP, default 80amp setting, plugged in to top off the 3% we used getting to the house, charge station insights said 3.008 kWh was used in 13 minutes, as a side note the trucks charging curve slowed the pace such that it was drawing an average of 58 amps over 13 minutes.

Ford pass said the home charging session of 13 minutes was worth 7 miles, which comes to an average rate of 32 miles per hour, cross check 7 miles / 2.33 MPK of most recent drive = 3 kWh

As long as you get to your targeted SOC before next departure, all is good, so if you are trimming the time frame to charge because of time of use constraints and the charging window is not sufficient for your needs, then you have to charge more during the peak rate time frame.

Anyone using/measuring their kW charge speed via the FCSP? I finally got my ODB dongle working so I could measure and got a reading of about 16.5 kW when my truck's SOC was around 50%. I have my FCSP wired to a 100A circuit and set to the full 80A in the unit and via the app. But at 16.5 kW that would seem to indicate closer to 70A being used? I don't have a means of testing the draw on the circuit to confirm, but just curious if others are getting 18 or 19 kW with their FCSPs. Thanks

Mine is on a 100A breaker. Measures 238V on the FCSP terminals with a 25 foot run and #2 THHN. Set to 80A. Measures 17.5kWh feeding the FCSP, meaning it's drawing around 74A.

If you have a low kWh reading, first thing I would check is your voltage.

I just installed a Emporia Gen-2 Vue, I was seeing ~17925 at 240v that would be ~ 74.7 amps

Isn’t the ODB data the net DC going into the battery? There will be conversion losses between the AC going into the truck and the DC going into the battery. There is also energy used for battery temperature maintenance. Maybe as much as 10% loss.

Here is how I would calculate my charge rate using the Ford Pass data - reference this screen shot from today:

Total charge added is 50%. I have an ER battery which is 131 kWh so total kWh added is:
131 kWh x 50% = 65.5 kWh.
Total charge time was 6hrs 12min (don't use the time plugged in number). This is 6.2 hours.

So the average charge rate is kWh/hours which is 65.5/6.2 = 10.6 kW.

Note I have the FSCP set at 48 Amps. Assuming 240 volts that is 240V x 48A /1000 = 11.5 kW theoretical rate. The FSCP reported 71.0 kWh sent to the vehicle for this session which is an average rate of 11.45 kW. Close enough. Note the difference in the 71 kWh sent and the 65.5 kWh battery increase are charger losses.
