AC charger 48 or 50 amp

[lcarron]

Hello

I got my new charger ready to be installed and the lightning pro with regular battery may arrive next week.
If I set up the charger to 50 amps can the battery handle 12kw? Or should I keep it at 48 amps?

To run at the full 48a you need to size the breaker and wire for 60a since it needs to be run at 80%.

The battery can handle a lot more than that.

A pro can only charge at 48 amps, unless it has the extended range battery. The additional cost to enable your EVSE to output 50 amps is cost prohibitive, even if it could utilize it.

I have a pro and charge at 48 amps. My charger pulls about 11KW. I’m not sure what tangible or noticeable difference you’d see between 48 and 50 amps?
As Blochead mentioned above- you need at least 6 gage wire for either 48 or 50 amp circuit.

That's not true. You need at least a 70 amp breaker and #4 wire for 50 amp charging. That is why it's cost prohibitive. The price difference between #6 and #4 wire, while only gaining, at most, .48kW, is generally not worth the extra cost.

48 amps is the maximum that a PRO-SR can charge, all SR-truck's can not draw more than 48a per the design of the single AC/DC charger.

continuous load @ 48a / .8 = 60a

Appropriate wire & breaker for 60a

Fully agree, about 20-30 minutes less on a full charge from 0 to 100% is very negligible.
Thanks

My calculations show that my Ford Mobile EVSE, supplied with my PRO, at it's typical 30amp rate of speed, can give my PRO more than 50% battery charging, each overnight 11pm to 7am timeframe(my Georgia Power 'EV Charging Rate Plan' time slot)...
6 kwh speed(per hour) ... 6 x 8 hours = 48 kw.... 1/2 of my 'usable' Battery capacity

This means that in a typical 2 overnight timeframe, I have FULLY recharged my FULL battery, if I have not driven any miles. If I subtract a typical 'day' of driving, even if it is 100 miles, I only use about 40% of my battery(average 2.5 mi/kwh)... but, I don't 'commute' everyday, like some might. I've used, though, about 2,500 miles on an average month since August 2022, including DC Fast Charging miles, of course.
I have RARELY, if ever, needed anything more than the typical 30amp EVSE. And, even if I DID need 'more' than the typical overnight's charging would provide, I simply plug in the truck ANYTIME during the day, if/when I need to, or can, if I am at home... I just pay more for 'power' outside of my typical overnight charging hours. I've rarely had to do even that.

In some ways, it pains me to see so many comments and questions about 'faster' charging at home, or even the cost of the FordProCharger and all it's additional costs, such as the wiring/equipment/service required to make it even happen. Then, you hear that even with that 'capacity', many have had to 'dial back' their amperage in order for it to work. I guess each owner does what they want, but I've always taken the 'start slow and easy' approach, using the basics to get things started, before 'wondering' about needs before actually having any practical experience. Probably much of the at-home charging equipment is overkill since most of our vehicles are parking there so many hours of every day, but, certainly, there are a few cases where that may not be the case for some. Those are generally exceptions, not the rule. A truck with an extended range battery pack may seem to be more of a case for this conversation, but I'll bet that owners with ER Lightnings don't necessarily drive any more miles than anyone else. The point, then, is not about 'speed', but since it can handle 'faster' speeds, those with these vehicles will be more inclined to try to meet that speed, even if it's not really needed, for practical everyday purposes.

nonsense.
a 50 amp service (80% rule) would require 62.5 Amp wire size, which (at minimum) 6 gage wire fulfills. The length of the run of course could require a larger wire.
of course, why anyone would go through the trouble to run anything larger than the largest charger the truck could handle (48 amp) remains a mystery, the mere fact that you called me out is the reason for this response.

The Ford Mobile Charger supplied with the truck supplies 30amps, unlike the Mach-E version which supplies 32.​

​

That is 7.2kW from the wall.​

​

With a 10% loss, that is 6.5kW. The Ford app will report 6, because it truncated the decimal place. Charge for an hour, and look at total kW supplied while still plugged in, and you will see the true power supplied.​

I have the Emporia 48 @ 240v wired to a 60 amp circuit. If the truck is low, I plug it in when I pull into the garage. Its always charged the next morning. Not something to worry about.

What charger did you buy that has option of 48 or 50 amp output?

Chargepoint Home Flex can do it.
