Charging Speeds at Home

Good advice. Reliability with the Ford Mobile EVSE has been reported by many as not robust.

Is it that it is not as robust or is there as safety issue as well?

Not robust. There have been no reports of safety issues to my knowledge.

MidAtlantic best me to it but to concure, I have not seen any safety issues either.

Generally the Ford mobile "charger" not as reliable as other EVSEs. Plus the plug to outlet can be an issue with overheating and melting the outlet, as with every mobile charger. When I refer to a "Charger" it really is an EVSE. Electric Vehicle Service Equipment. The actual charger is in the vehicle.

The best solution is to install a hard wired EVSE. It eliminates the plug/jack heating issue and eliminates the need to have it wired to a GFCI circuit which is required by code in some areas.

Many reliable hard wired EVSEs are out there. Tesla Universal Wall Connector, Grizzl-e, Emporia, Charge Point etc.

In the 10 + years for EV ownership my vote is for a Tesla Universal Wall Connector hard wired to a 60 amp or 50 amp circuit. It gives you a J1772 plug for your Lightning and a Tesla NACS built in plug. In the next few years almost everyone will have Tesla NACS charge port so you are future proofing.

I had an old bulky hard wired Siemens EVSE for 8+ trouble free years. I replaced it with a Tesla Wall Connector about 2-1/2 years ago. I also installed a Tesla Wall Connector at our cabin. I couldn't be happier.

I just had a 50 amp RV hookup installed at my house. I plugged in my Ford charging cable and it reached a maximum of 6.6 kw/hour. Is that the fastest one can charge with the standard Ford charging cable? Thanks.

I upgraded the wiring for 80 amp, and it charges at 19.2 kWh per hour. I own the Lariat ER.

So If i change my breaker to a 60 amp (currently a 30amp) will that increase my charging ability with the supplied ford charger? would that be safe? its a 23 XLT

No.
However for a 30 amp load, you SHOULD have a 40 amp breaker and wiring size to go along with that. Also note that since the NEMA 14-50 outlet that the mobile charge cord plugs into is a 50 amp outlet (and it is reasonable to assume that it really could be used for up to a 50 amp load), it really should have a 60 amp breaker and wire size to go along with that. However that will not make the mobile charge cord charge any faster.

Danger Danger Danger!!!!!

You should not be using the Ford Mobile "charger" on a circuit that is rated for 30 amps.

1- A 30 amp constant load device requires at least a 40 amp circuit (1.25 x the device amperage or 80% of the circuit rating) . A 30 amp circuit can only legally handle a MAX OF 24 amps. That 40 amp circuit can legally handle a MAX OF 32 amps

2- You simply cannot replace a 30 amp breaker with a 60 amp breaker to increase the capacity of a circuit. You must also have the proper wire gauge to support 60 amps.

3- FINNALY- THE FORD MOBILE "CHARGER" PROVIDED WITH A LIGHTNING IS FIXED AT 30 AMPS NO MATTER WHAT CIRCUIT IT IS CONNECTED TO !!!

Yep the wiring is 4 gauge. not a problem there. When I initially installed I was thinking of a 60 amp breaker but downgraded to 30 after. I may just go back and install a 60. Thanks

If i wired with 4 AWG Copper then I would buy and install one of the highly rated reliable Hard Wired 60 amp EVSEs. The I would keep the mobile charger in the Fronk to use when traveling. THHAT IS WHAT I DID.

The Ford Mobile Power Cord says (on the back of mine anyway - see image) 32A max, so at 240V that's 7.6kW assuming no losses.

But perhaps they operate at 30A as some contend, then 7.2kW max with some losses at 240V.
So your output seems lower than would be expected IF you have a 240V circuit.

But is you outlet voltage 240V?
If it is say 220V, then that's why you get 6.6kW: 220V x 30A = 6,600kW

Regardless...the FMPCs have a spotted record based on posts about failures after relying on one exclusively for charging for some period of time (months).

On a 50A 240V outlet you could charge at 40A (80% rule and NEC code for plug-in EVSEs).

So find a better EVSE suitable for daily use that can charge at 40A. Or higher if hardwired on an appropriately wired and protected (breaker) circuit.

If you have an SR battery, the limit is 48A (also for some 2024 and later trucks with larger batteries).

I expect Webasto downrated the chargers internally but didn't change the labels. Mine looks exactly the same on the back.

You can test your charger a few ways:

1. Use it to charge your Lighting. See what the charge rate is on the FordPass app.
2. Use an ammeter to measure the output. You will find a square 30A draw during charging.
3. Plug it into the ProPower Onboard of your truck and charge an EV (or charge your own truck) using the 30A 240 outlet. This requires an adapter to go from the 30A outlet to your NEMA 14-50 on the charger. If you have a 32A charger, it will quickly pop the circuit. If you have a 30A charger it will work just fine. I gave a Fiat 500e half a charge this way at an EV display event Saturday.

Yes, thanks, I guess that explains it.

I put mine away in the Frunk ice bucket under the cover, but I thought about checking it too.

I used it when I first got the truck - had a 30A J1772 set up on a 40A breaker for my 2012 Nissan Leaf through a 6-50R for the 6-50P that my GE WattStation came with and got an adapter to use the FMPC temporarily. I took down the GE EVSE but then I read about all the issues with the FMPC so I put the GE back up for the Leaf and put the FMPC away in case of an emergency, like a stranded EV on the road.

I'm an EE so I know how to check the current, if I could find my ammeter, lol, but I'll take everybody else's word for it that it is 30A. It makes sense if the idea was to use it with the 30A 240V bed outlet.

Nice of you to help someone out on the road, we EV drivers have to stick together for sure! Those compliance EVs don't have a lot of kWh's in their batteries, a friend of my wife's has a Mini Cooper EV with pitiful range - about the same as my 2012 Nissan Leaf - well not much room for battery on a Mini Cooper.

Chris,

Mach-E and Lightning Mobile EVSEs are the same except for the pigtail.

If the pigtail for your mobile Ford OEM EVSE has a piece of yellow tape on it, then it is limited to amps. If no tape then it is the 32 amp version.

The Lightning's ProPower 240vac output can handle 30 amps continuous , unlike a typical home dryer outlet which is code limited to 80% of circuit rating for continuous use.

Tesla has multiple cords that will change the output of their mobile connectors. I have a 14-30P plug version for my Tesla Mobile Connector that plugs into my 4-wire 30 amp dryer outlet and limits the Tesla Mobile ESVE output to 24 amps.

Here is a picture of a 30 amp Lightning pigtail.

To add to this.

The Ford mobile charger is a rebranded Webasto Go, which other OEMs use as well. In other areas you can change the pigtail of the unit to tailer the output for a specific plug and current.

Folks on the Mach-E forum tried the TT30 end for the Cadillac charger but found it didn't work on the Ford mobile charger.
