ChargePoint Discount

There's really no reason to go with a 70A breaker, which would require even thicker wire. Just go with 60A. That will give you the full 48A charging speed of the Mach-E.

You may be right that the Mach E charging tops out at 48A but have you found that in writing anywhere?

No, just that the Ford Connected Charger is 48A. If the Mach-E could do more, I would imagine the charger would match it, but I guess we don't know that for sure. Even if it's higher, it still wouldn't make sense to go with a 70A breaker for the Flex since it tops out at 50A. Not worth the thicker wire for an extra 2 amps.

I concur on the minimal difference between 48A and 50A charging. It's odd, though, that we have never seen actual charging specs for the car.

So tempted since that CP Flex is on discount....

However, I already have wayyyyyy more battery than I need (88 kWh) and have two functioning EVSEs at home (L1 and L2) so I think I will put my credit card away and just use my existing equipment.

Same here, would like a smart charger but I already have 2 chargers with 1 more coming with the MME.

Yeah, it is odd. The specs of the onboard charger are usually clearly advertised for EVs. I hope that doesn't mean that it's less than the expected 48A. Though the charging times that Ford has been quoting with the Ford Connected Charger lead me to believe that's not the case.

But the chances that it's higher than 48A are pretty slim. Are there any current EVs (other than Tesla) that can do level 2 charging at more than 48A without resorting to some dual charger setup?

Taycan goes up to 11 kW when using AC 3-phase.

Okay, but in theory, if the Mach-E can really do 48A at 240v, that's 11.5 kW.

Agreed. Maybe even at 12 kW with current peaking to 250v.
ClipperCreek seems to think the Mach E is limited at 10.5 kW:

The problem is we just don't know.

My utility (DTE) has a program .... enroll in one of their programs for getting a special energy rate for charging EV's at non-peak hours). I do plan to enroll in the program (I've already had the work done to install a new meter dedicated to EV charging) but they don't activate the program until I've taken delivery of the car...

Be careful of programs with special rates for off peak charging. Often they are tied to your accepting (much) higher rates at other times. Even with a separate meter here.

For us, the discount on charging the car and other activity we could move off peak would have been overwhelmed when applying the increased rate to our usage during ‘normal’ hours.

That difference would be even greater now during pandemic with everyone working & eating at home.

My utility requires at least some type TOU plans if I average over 1,000 KWh per month. So pretty much everyone living in a house has to have that. They also provide an online tool that estimates your annual cost assuming that you don't change usage patterns. Based on this tool, I would save the most by choosing the maximum plan. In August, our worst month, I paid $59 for off-peak usage, $10 for on-peak, and $59 for on-peak demand charge (plus various and sundry charges of $80 that are not based on usage).

My peak hours are 3 pm - 8 PM M-F. That's fairly easy to put up with. Still, it's not that hard to shift your usage to reduce the cost.

For you, perhaps.

Peak is 12-8 pm by our utility decree. In their defense, they select that third of the weekday for a reason.

I am suggesting everyone should do their own review and not rely on a simple comparison of their current residential rate and the teased off peak rate in the brochure.

My charge point is installed to a 60A breaker. Easy to set up and connect to WiFi. So far, I am happy with the purchase. It recognized my utility company and let me pick my plan.

My super low-rate starts from 10 pm to 8 am. I prefer the charging to start at around 3 am when the ambient temperature is the coolest. During summer, the garage can be quite hot, even at 10 pm.

It will be nice if Mach-E has the intelligence to schedule the charge complete-time instead of the start time.

I would like it to finish charging at 7:00 am. If I traveled 100 miles, it would know to start charging at 4:00 am (30miles/hr).

When you set up your Mach E in the charging screens it has the ability to set up charging locations with particular parameters. This should be in there. It also allows for both start and end times for charging.

If both EVSE and Car have the ability to schedule the charging start/stop time, which one would be the better choice to assign the schedule to?

Either. However, the EVSE can set the schedule for itself only. The car can have schedules for multiple locations e.g. work or your brother-in-law's house that you are visiting, or your cabin in the mountains.
