Mach-E (Extended Range) Seen Reaching 120kw Charging Speed

[dbsb3233]

So doing a little extrapolating (and assuming)...

• Picture shows it still charging at 121 kW @ 42% SOC.
• 42% of 88 kWh usable battery = 37 kWh. However most measures assume people recharge up from 10%, so let's use 10-42% = 32% of 88 = 28 kWh.
• If it starts at 150 kW and falls to 121 there, let's just say that's a 135 kW avg for the first 42%. (It might be weighted more one way of the other, but it's probably near that.)
• 28 kWh at an avg of 135 kW = 0.21 hours = 13 minutes.

The 300 mile range on 88 kWh = 3.41 miles/kWh. 28 kWh x 3.41 = 95 miles. 95 miles in 13 minutes extrapolates to 73 miles in 10 minutes. That's even better than Ford's revised "61 miles in 10 minutes" for the early part of the charge curve.

Now to project onward...

Let's say it tapers evenly from that 42% mark out to 80%, from the 121 kW down to 50 kW by the 80% point. That's probably a fairly safe (and slightly conservative) assumption, as BEVs of this capability rarely taper down below 50 kW at 80% SOC.

• That would make the average power rate 85 kW from 42-80%.
• 42-80% of 88 kWh = 33 kWh.
• 33 kWh at 85 kW avg rate = 0.39 hours = 23 minutes.
• Add the 13 minutes from 10-42 to the 23 from 42-80 and we get 36 minutes from 10-80. Better than Ford's stated "45 minutes 10-80".

Rough assumptions in there. But still charging at 121 kW @ 42% SOC is very good sign by my estimates.

Pretty much exactly what I said months ago, but you dismissed.

This was the extended range battery. I have the impression that Ford is limiting charge rate on the standard range battery to 115 kW maximum. Am wondering what the real world numbers will end up being.

I'm not sure about the 115 kW charging spec. According to the spec on ford.ca all models can charge up to 150kW, because of course they will never tell that it is charghing at 150 kW but only up to, and according to a spec sheet fund on internet the Select model is rated at 115kW but all the other models are at 150kW independantely of the size of the battery. My belief is that at the beginning yes 115 kW was suppose to be for SR battery and 150 kW for ER battery but that has change since and the specs now states what I"ve written here. Here's from ford.ca spec page

Charge Capability -SAE J1772 CCS (Combo Connector System) Charge Port capable of charging on 120V, 240V and Direct Current (DC Fast Charge) Power and Heated Glass -AC Charging: Up to 10.5kW with 48 Amps capability -DC Charging: Up to 150kW capability -LED Charge Status Indicator on Charge Port with Courtesy Illumination

and it's for all trims and both battery.

I never dismissed the possibility. I said it simply didn't fit what Ford was/is telling us ("10-80 in 45 minutes", even after the revision). And we had no other data points at that time to show that what Ford was telling us was incorrect.

Now we have one. Albeit one anecdotal example, but a compelling one.

no it’s not a First Edition. The FE has same-colour wheel casings (don’t kno the exact English word for it) where these are glossy black on the picture.

FE= same color as body
AWD/Premium = glossy black
RWD/Select = mat black

Yes but it has red calipers

Yes but it has red calipers

AWD/Premium also has Red calipers. Check your local Ford website

Only in Europe.

I still interpret this as up to 150 kW for all trims except Select, and only because Select isn't available with an ER pack. So I believe all SR models are limited to 115 kW for now.

But we shall soon find out!

I don't think so but it's a pre prod model so it's not necessaraly the reel thing.

I don't think you can do this math based on this picture as its only been charging for 49 seconds (see picture).

The way I read that picture: they plugged the car in when it already had 42% battery. So this image is showing a starting rate of 121kW. Granted yes its 121kW at 42% but you don't know from this picture that if you started at 10% the car would still be at 121kW at 42%--it may have started to taper before this point.

EXACTLY. The Select which can only have SR battery says "up to 115kw" and the other trims that can have an ER battery say "up to 150kw" - with no further explanation. Since the difference between the SR and ER battery is an additional 30% set of cells that are wired in parallel (to keep voltage the same) it makes sense that they can charge at a 30% higher current.

Can you remind us what you said before?

The bigger problem with this "test" is that they start at 42% SOC. I didn't read all the subtitles, but unless they started charging ALL the cars at 42% then these rankings are bogus.

The compare specs page from the UK web site also provides compelling indication that charge rates are limited by pack size.
