Lightning to Mach-e Charging

Another few questions.

What charge rate (kW's) does the Mach-e EVSE supply to the vehicle? 7.6 kWs, 7.68kWs or 9.6 kWs?

30 amps should be 30x240=7,600 watts aka 7.6 kW's
32 amps should be 32x240= 7,680 watts 's aka 7.68 kW's
40 amps should be 40x24=9,600 watts aka 9.6 kW's

Regardless a 30 amp continuous load on a 30 amp house circuit is not legal.
Is the Lightning designed and legal to provide 30 amp continuous?

At my house I use a tesla mobile charger as backup in case my Wall Connector doesn't work. It plugs into my 30 amp 4-wire dryer 14-30R outlet. Since a 30 amp house circuit is legally limited to 24 amps continuous Tesla has a special dongle that limits the current to 24 amps when using a 30 amp dryer outlet. The charge rate with that setup is 5.76 kWs

Here is a picture of my Tesla Mobile adapter dongle that limits output to 24 amps on a 30 amp outlet

30x240 = 7,200, not 7,600

The Mach-E charger is 32amps.
The Ford Lightning charger is 30amps.

The truck delivers 30amps all day long via the circuit in the truck, each leg is limited to 3,600 watts. I believe there are many threads on this.

Your Tesla dongle limits power just like the Lightning's dongle limits power.

Thanks for the math correction on the 30 amp output

The reason I asked the questions is that I am confused about the Mach-E charger output . The Dongle shows 40 amps. Has anyone confirmed the charge rate on the car at 32a 7.6 kWs or 40a 9.6 kWs?. The YouTube video from Martin Rebuilds states 40a for Mach-e charger.

Martin is wrong.

Yes, the dongle for the Mach-E is rated at 40amps. Now, go pickup the Ford Mobile Charger base, and read that label. It maxes at 32amps. That's what allows the Mach-E to pull 32amps from the wall, whereas the Lightning can only pull 30amps. Same base unit, different dongles.

The derating for household circuits is because houses are wired with cheap wire routed through wood studs inside insulated walls. It’s impossible to know the condition of the wiring so there is an additional safety factor added. Every Lightning is built with high temp wiring routed through steel and aluminum and Ford has test data that shows it is safe to draw 30A continuously. Also, the circuit protection on the Lightning is much better. If you draw 32A through a home circuit breaker the thermal trip can take anywhere from 90 seconds up to 2 hours to trip. The Lightning is actively monitored and if you try to draw 32A it will trip immediately.

Yes, you can charge a Mustang Mach-E (or any EV) from the Lightning's Pro Power Onboard.

You need to use the F-150 Lightning's Mobile Power Cord 30A NEMA 14-50 grid cord (with the yellow band) but you can use any Mobile Power Cord itself (the grid cord is what tells the Mobile Power Cord to limit power flow).

Thanks for the explanation and the link.. Now it clears this up for me.

Tesla has an assortment of dongles that adapt the mobile EVSE to different plugs and circuits. Plus Tesla allows you to dial down the charge current on the car screen. I wish Ford did the same. There are times when I want to charge at only 24a or 32 amps with a 48a EVSE.

From Tesla site. These are their 7 dongles for their mobile charger.

• 1x Gen 2 NEMA 5-20 Adapter (4a?)
• 1x Gen 2 NEMA 6-15 Adapter (12a)
• 1x Gen 2 NEMA 6-20 Adapter (16a)
• 1x Gen 2 NEMA 10-30 Adapter (24a)
• 1x Gen 2 NEMA 14-30 Adapter (24a)
• 1x Gen 2 NEMA 14-50 Adapter (32a)
• 1x Gen 2 NEMA 6-50 Adapter (32a)
