How much is "Complimentary 250 kWh of DC fast charging at Electrify America stations" ?

[RickLightning]

On the Mach-E, disconnecting from a DC charger is best done by pushing the button next to the charge port on the car. This avoids errors.

@TaxmanHog, you won't be making 20 minutes stops, I promise you, unless you don't need much charge.

No doubt, total NEWB here, I'm forecasting a 50% loss pulling, I'll plan for extra time, I'm on the road at 0500 anyway, plenty of time to charge up after driving ~60 to 70 miles depends on taking I95-RT3-I495 or I95-I495, so that's like having gone 120 to 140 miles running light and being in the area of 50% SOC. As long as I'm at the pit gate by 8am to set up I'm good.

Chargepoint stations are typically only one or two 'dual' units: a CCS and a CHAdeMO. Chargepoint, though, many times uses a 'shared' electrical system, of 125kw. If only one vehicle is charging at one of the pedestals, and can access up to that maximum, then it will allow it. If ANOTHER vehicle is also there, or comes while you are charging, the electricity gets 'shared' between the two pedestals - meaning that the max you might can draw is 62.5kw. I think this is to limit the cost of these installations, limit the draw on the utility system, and basically create a simpler overall charging option for property owners.

What is frustrating about Chargepoint is they are not even forthcoming about their power limitations. These "paired 62.5kW for 125kW" machines can deliver... a maximum of 200A to the vehicle (and sometimes 174A). That means you will not get more than 200 x 400 = 80kW from a pair with a nominally 400V vehicle. Their level 2 stations are also very underwhelming at 30A or 32A max which at 208V often connected at makes for very low level 2 charging speeds. It's sad since their hardware is so nice and generally reliable.

Almost all chargers need to be considered to have some or a lot of derating.
When Ford mentions some number like 125Kwh that means it is on a perfect day.
Charger companies may have a dedicated 125KWh device but it may not ever offer that much. To top it off the charging companies buy power and it can be that they derate the charger during peak loads. They will for sure derate every charger that is dual and two people trying to use it. You simply can't use the max number. I've looked back at chargepoint graphs for the last few years and some have been very low speeds and inconsistent current levels. Gets worse the closer you get to 0 or 100%. Only a small sweet spot exists.

going back to the original question, the answer is a little more charging than 249 kWh would supply, and a little less than 251 kWh would supply.

250kWh means 220kWh saved in battery and about 400 miles on freeway.

So....where is the free 250 kWh? Do I need to do anything to redeem this in the Ford Pass app? I can't find this anywhere in the app, or is there something I need to do to link to the EA app?

Or do I just connect to any EA station and it automatically starts ticking down my 'free' 250 kWh?

Did you go to your Ford Pass app under Vehicle - Charging - Blue Oval Charge Network ?

When you activate it, the EA charger will automatically detect your Lightning and start charging.

After your 250kW complimentary, you will have to load money onto the EA app.

Yup that's where it was hiding, thanks for the help.

In Texas EA has tiered per minute pricing. From what I understand, the Lightning charges at a max of 155 kW, so it would be 32 cents a minute?

Some good info on actual charging curves here. One graph from that page is pasted below. If you really want to pinch pennies, it's cheapest to start your charge from 30%!

The rate of charge after 90% is appalling, and something everyone should be aware of when planning a trip.

• -In per-minute locations, how does power level pricing work?
  When you plug in to charge, your vehicle tells the charger the maximum power it can accept. Based on that communication, your vehicle will be assigned to the corresponding power level offered by the charger.
  Your charging speed may fluctuate due to factors like weather, age of your battery, and how full your battery is (your state of charge). The per-minute price stays the same for the entire session, regardless of how the charging speed may vary.

EA has per minute rates in about a dozen states. You will pay the top rate, 32 cents a minute, IF you aren't using your free charging hours and if you don't join EA Pass+ after that. Pass+ is $4 a month, you can upgrade then downgrade minutes later and it will take effect in 30 days. It lowers the rate to 24 cents per minute in per minute states. You can see what states charge by the kWh vs. by the minute on EA's website.

Per minute charging is about 50% cheaper than per kWh charging up to 80% state of charge. Then, when charging speed slows, it will be a much closer comparison.

You don't want to DC fast charge above 80% unless you need the range due to speed of charging, and in per minute states possibly cost.

This is good info if I run across per minute rather than the per kWh charge.
