Well that does the job.. Now just need to charge up that battery before charging the battery.
Is your fan a Ford model or some knockoff. I am afraid of using something not manufactured by Ford because they make it specifically for this purpose

Oh it’s a Mustang but voided it's warranty by charing that battery above 80% in the summer and using it until it was dead. So far it hasn't jailbar'd me but I hot the 5 second limit constantly, So I electrical taped the safety wire out of the way.

* The above is all sarcasm. You can't get my factory charge door cooling system, but Suma might release one that looks just like it soon, after they figure out the BLIS

Well we finally have a scientific answer to our questions- we all have to buy leaf blowers if we want a fast charge at home.

I feel so relieved

But why not just make 10 faster and make 10 the highest?
It's 185 MPH! I don't think the charge door will stay on lol.

On I misread that reply. It's on 1.0 now, I meant turning it up. to 1.1. Maybe going to go to something in the middle, say 4.2.6 but figured why not just try 6.1.7 following the power up numbering. But I'm still waiting for the BC 1.2 (Blower Charger 1.2, but I'll probably never get it because Job 1.0 car and blower. sigh.) And I never got EA access.


After nearly 2 hours on the charger charging stopped fully for a couple seconds and NOW my cooling fan is on.

My Level 2 charger in the garage has now done the same thing, almost to the day of one of the automatic updates. Used to get about 20 miles per hour added. Now its much less. KW went from 9 to 3 and I got the amber/blue light on the Ford charger. Its warm here, about 85 and humid but I never had this issue last summer. Also, tried to charge at night and got the same result. Should I report this to Ford, maybe get a new Ford charger under warranty or is it the software limiting the charging ability due to heat at the charge port?

Now that the cooling fan is running it ran the fan at one speed for about 3 minutes then started ramping that up faster for 10, back down, then back up, then back down. Sounds like someone trying to fix high idle on a carb in my garage.
(Edit: it stopped, charging, completely, again, then started, again, with no fan.)
I'm going to take the charging turbo off so this thing down' try to melt it's self to the ground in my garage.

Are you trying to tell us that your scientific findings might get not be what they seem to be?

Or just afraid the fan and the car charge port will melt

It just threw a curve ball. It's cycled the car fan twice, and restarted the charge, twice. Now it's charing at 40 solid with the car fan running on low and the leaf bower out of the picture. It's been charging for over 25 min (longest I've seen before a drop in amps) without the blower, the garage and all other temps higher than started and the cars fan running on low.

Something I noted about the way it's charing now, the air from the cars fan, is most likely cooling some other sensor somewhere. One that wasn't cooled by the leaf blower. Which would explain the rain having a better effect. With the way the fan is running now air if coming out of the wheel wells in the front. Remember my cooling fan never started this morning and didn't start until the first crap out. It has now charged to 85% and stopped (my target) without cycling the amps since the second crap out.

So the leaf blower is not the fix :( I had hopes and was charging its battery as soon as I read it ;).

It helped, but I think it really depends on if your cars fan starts at all once plugged in. Mine didn't start until almost 2 hours into the charge when it actually stopped and started the charge by it's self. It was sitting all night in the garage ~ 105 degree soak at 9pm -> prob 90 degrees by 8am.
