2024 Mach-E charging curve comparison vs. 2021 Mach-E

[Nolanbro]

The ID.4 has a nice smooth charging curve Ford should aspire to. I think the Mach-E is limited to 450 amps or less, so a charger limit of 475 amps will still provide max power unless there is also a charger power limitation. I have not heard of anyone getting more than 165 kW in a Mach-E. No offense, but I think you’re misremembering seeing 200 kW on a Mach-E.

Ford is excessively paranoid about the cell temps and limits it to only 104°F. They should allow up to 122°F during DC charge like everybody else does (Tesla goes up to like 140°F). I think the ID.4 uses similar LG cells, so I’m really not sure why Fords charging curve is so nerfed in comparison.

I think I misspoke about the 200kW. I meant I've seen my ID.4 take that much. Mach-E has only taken 160 in my experience. It was running battery and cabin heater. I think it might have actually been taking slightly over 500amps but not sure as carscanner wasn't hooked up. But ID.4 voltage is only around 380 when charging, so I assume it was taking over 500 from the charger.

The EA station I used was limited to 475 for the VW. It was one of the 350 balanced units and the other dispenser was out of order, so that could've been a factor. I don't know if it was a dispenser or power cabinet issue. I want to say I've seen the Mach-E hit 460 before, but I think it was 460 from the charger, not into the battery (I believe it was EVgo and that reading was from its screen). I agree with Ford being way to conservative on battery temp. That must be changed for 24 or that charging curve wouldn't be possible. If remember my old Niro EV would actually throttle charge rate at 95F. Im 90% sure those were SKI cells not LG Chem.

Who do we need to slip a bottle of some quality Scotch to so that we can get our ER battery packs uncorked?

This is the chart for my most recent fast charge.
Car is 2024 MME Rally. This is consistent with what I saw on my road trip MI -> OK -> CO -> MI

Based on other sessions, the rate after 80% is ~40 KW to about 93%.

Its pretty interesting how the charge rate drops and ramps back up like that, not sure if it was thermals or just a constant amperage request, but still much better than the older cars

So here's something I found out. The 21 ID.4 used to only charge at 125kW, as of last year, these cars were updated at the dealer to software 3.1 and are now able to charge at 170kW. Whats pretty crazy is these cars use the SAME battery cells as the Mach-E. The id4 was sold in '23 with SKI and LG Chem cells, but it appears the LG chem cells that were present in 21 and 22 id4 have similar charging curve to the SKI cells, slightly lower peak but still in the 170kW range.

So who knows whats holding ford up. If their cabling is capable of 500amps, they in theory could go even faster with charging speeds IMO.
