Edmunds Massive Charging Comparison - MME is second to last.

So you’re saying the GTPE’s are holding the rest of us back!

Funny, the Mach E has been out long enough for Ford to have oodles of charging data. You'd think they would be able to use that data to massage the curve or top charging speed a bit more so it means less time at the charger.

I am not an engineer, nor have I stayed at a Holiday Inn Express. But, I suspect that Ford hasn't tweaked the charging curve since 2021 for the following reasons:

- they are worried about the HVBJB, and didn't want to jeopardize more of those failing, but that's now mute.

- few owners are on a forum and understand the term "charging curve". Since any gain would be mere minutes, there's no upside, and lots of downside.

Edmunds did a comprehensive charging speed test on dozens of EVs in the US market.

Out of 43 tested vehicles the MME 4X and GTPE came in #40 and #41, respectively. Only the Bolt EV and EUV were slower to add miles.

I’m curious why different trims of the same car would have different charging curves. I get that a bigger battery takes longer to charge but that is not how the article is measuring. Instead it’s miles added per hour.

Assuming the various trims have all got the same electronics shouldn’t they all charge at the same rate?

The SR Mach-E has a different curve than an ER Mach-E.

I’ve seen a tear-down of the MME battery pack. The HVBJB has no active thermal management system to speak of.
From what I’ve seen, their only option to regulate heat is to limit the power flowing through the module.
The car is well engineered, over all, but without active thermal management throughout the entire HV system, heat will always be the Achilles Heel.

But why?

This is my thinking, also. Even with the 400v architecture, Ford could loosen up the constraints of our charging curve to make things a bit more competitive. I've been calling for "dynamic" charging for a long while - adjustments to the curve, and even capacity, based upon how often you DCFC. There's no reason I shouldn't be able to charge faster for longer on the curve, and even charge to 110%, if I only DCFC less than once a month.

This does not matter to me.

This is all about 'use case.' I knew the US infrastructure is not built for EVs, but I bought one anyway. Why? Because 95% of my driving is less than 20 miles per day; 4% is a 150 mile trip every other week; and I have taken ONE road trip of 2,500 miles. Stopping to charge during my road trip was a 45 minute exercise (to find a working charge station in some random neighborhood, waiting my turn, connecting and then charging). I have owned my MME GT PE for 510 days and have charged at home for 500 of those days. If I wanted to eliminate the 45 minutes on road trips, I would buy an ICE vehicle and miss out on the best car I have ever purchased- the MME GT PE. Charging speed really means nothing to me.

On balance, I'll take the tradeoff in range for all the fun I get every time I drive my GTPE! My driving experience since June 2022 much like above, mostly charging at home, one long trip and several medium trips with DCFC charging. This is very similar to the tradeoff I always made in ICE vehicles: I drove sports cars for the fun factor, and I had to stop for gas a lot more often than cars with better gas mileage and larger tanks!

The data is not only about how fast you charge, but also how efficient your vehicle is. That’s why you see a significant difference between premium and GT even when they have the same battery and charge curve. The premium is slower and more efficient.

This is an “all in” view based on how many miles of driving you can recoup when charging for an hour.

I'd be interested to see how the Mach E performs against the likes of the Toyota/Subaru, Nissan, and GM ultium battery cars. Right now the list seems like it's lacking the US and Japanese brands. So maybe they started with the start up/new kids (Tesla, Lucid, Rivian), German, and Korean brands.

It'll also be interesting when the list is a bit more complete to see in general how the brands/regions stand up against each other. Right now it's not a positive reflection of the US legacy auto makers compared to all others.

I see te MMEs rate from a little below to a bit above 300 miles per hour. There probably is a curve somewhere on this site so ...... Is 150 miles half an hour, or maybe 20 minutes?

Ho Hum, I guess I'd rather drive a good looking EV that's fun and has the features I like. This has minimal impact on the majority of EV use. It will sort itself out in time as more experience with battery usage and charging focuses the charging infrastructure in all vehicles.

If I had to rely on DC fast charging or took a lot of long trips I wouldn’t get the Mach-e. But since I don’t it works well for me.

 

[LincolnLuvr]

Was hoping they tested the new LFP batteries on the standard range Mach Es. Don't those have better charging curves?
