11kW Charge Rate From Ford 48A EVSE?

[devmach-e]

To be whining about 9.8 and not 10.5 is ridiculous when some of us can not get over 6.5

I can't get over 6.9 kW (according to Ford Pass). But that's because my hardwired EVSE is only rated for 32A (7.68 kW).

I will when the tech gets to the point it makes sense. It will be with a product that actually has a half decent charging curve, a NACS port and definitely not something with a ford name on it.

What are you currently using for an EVSE? Is it a 32A unit?

40 amp that now charges at 4.4 and 2.2 KW averages around 6.5 Kw on long charges. When I first got it there was nothing on the app but would % charged x 88 KW / time in hours and was always 8.3 to 8.5. You know making the car have some value and not a legacy piece of crap.

That sounds like either a problem with the EVSE or your inlet port. I suspect the EVSE or its electrical connection.

For an understand you can look at the laboratory EPA test attached page 5. This is carried out in ideal conditions and therefore depending on your conditions may vary. Your charger is capable of 48 amp 48 x 0.24 KV = 11.5 KW. 11.5 x 0.87 efficiency is 10.0 KW max into the car. Your 9.8 looks in the ball park. At a stead 9.8 your 10 to 100% time will be 0.9 x 90 KW/ 9.8 = 8.3 hours. It slows down when going from 90 to 100 so a bit longer. If you sleep you should be good.

Thanks!

My own experience with the Grizzl-e 48A is between 10.5 to 11.1 kW depending on line voltage.

This seems to provide some insight.

And it absolutely does not slow down between 90% and 100%. It is pretty much the full amount all the way up to about 97% or 98% SOC. Again, tested multiple times.

Minor correction: It is the full amount easily up to 99%. At least on a 30A/205V EVSE at we have at work.

So….here’s a follow up I’ve been meaning to post. There’s a discrepancy between what the app is reporting, and what the car is reading in the GOM. see the attached pics. It appears that the vehicle is actually charging at a rate higher than what the app says…shocker.

The app reports the energy entering the battery so there is some AC to DC conversion loss there.

See my recent post. Seems like it’s the reverse. The app reports a lower value than what the vehicle’s AC to DC converter is reporting that is going to the HVB.

The dash is actually reporting the power from the wall, so yes it will be higher than what the app is reporting.

I don’t know why Ford doesn’t make it consistent between the two.

Right?
