Excellent Q&A with Ford/Mach-E Electric Vehicle Engineer

[macchiaz-o]

We probably won't know charging curves until people own the car and report enough stats.

Currently, Ford's indicated that the max charging speed is 150 kW for the ER models and 115 kW for the SR models.

I don't think the charging curve for the Mach-e has been released yet. Many people are anxiously awaiting it.

Ford advertises the charge rate (presumably max) at 47 miles per 10 minutes on a 150 kW DCFC charger.

I think that is when the battery is at low SOC. They also say on the website that the ER will charge 10-80% in 45 minutes. In the press release they mention that the SR will charge from 10-80% in 38 minutes.

Perhaps @1pt21Gigawatts can add a little to that info?

Those numbers are consistent with Ford's 47 miles per 10 minutes number. 10-80% of the 300 mile (RWD) ER battery is 210 miles in 45 minutes = 46.66 miles per 10 minutes.

That 38 minute SR figure doesn't work out quite as close though (230 x 70% = 161 / 38 mins = 42.36 per 10 mins)

Right, there is a footnote at the end of the line that says 47 miles in 10 minutes; the footnote states "when properly equipped with extended range". The SR has max 115kw DCFC compared to the ER 150kw DCFC.

We'll probably see a charging session on the MME 98.8 kWh pack that is more or less the same as a Tesla 100kWh pack (pre and post Raven). For the last 3+ years, it's been ~45 minutes to go from 10% to 80%, regardless of 120kW or 150kW charging. The biggest change has been at the bottom of the charging curve with improved times to 50-60%.

Tesla advertises the Raven long range pack as having 200kW capability but I have yet to find anyone posting that they get more than 140-150kW from a v3 or Ionity charger.

What I would love to see is a charging profile that is like the Audi e-tron. That thing is a monster with it still pulling over 120kW at 80%.

Do any BEVs really charge at 600 miles per hour at 150 kW?

Granted, translating it to miles is where it gets really fuzzy. That depends on how many miles the vehicle typically goes on a kWh, and that varies by model and trim.

Ah, I missed that. That's interesting. Wonder why the smaller battery pack would charge at a lower power rate? It makes sense that it would taper sooner, but pre-taper seems like it should be the same.

I guess the good news is that it should get the lower (125 kW) rates on EA.

I ain’t spelling no beans. But yes the ratings are for 10-80%. The only other comparable thing out there is like a model X. Don’t know why every Tesla person seems to forget the model x and model s are capped at 150kW charging too.

Now that I try to run the numbers, that 47 miles per 10 minutes does seem low, unless it's got a lot of tapering in it (i.e. not just the max rate at low SOC). At a full 150 kW charge rate, that's 25 kWh per 10 minutes that should be going in. 47 miles would only translate to 1.88 miles/kWh. Surely the norm will be somewhere closer to 3.5, not 1.88.

Maybe that "47 miles per 10 minutes" charge speed is averaging in all the tapers for a full 0-100% charge? Or a 10-80% charge?
