OTA Mach-E DC Fast Charging speed and threshold increases coming this winter

[GoGoGadgetMachE]

That's what I'm thinking, explains why there aren't any of the professional reviews of the GT yet

The video says that the press day hasn't happened yet... Even the well-connected Tom only has been a passenger so far. There was a passing comment about "some customers got early delivery" or some such.

When/where did he claim this? Your embedded video didn't load when I first opened the page, sorry.

Great news for sure if true.

That being said, I didn't have any issues on my roadtrip with the current "curve", was always to 80% before I was even done eating/bathroom/etc. Of course faster/better charging is always appreciated. Guessing they have enough customer charging data to work on it.

Just wait: once the Mach E starts charging to 90% we'll have people complaining the total charging time is too long -- better to drive an ICE!

Of course, the computer can not predict how fast you intend to drive on the interstate, so I assume it predicts based on the speed limit (plus 10 perhaps?) He said that tech is available now in the MME. Time to put it to the test.

This feature was touted in Norway at launch, so the GOM has been throughly disappointing.

The two major factors for my range (cold climate) has been elevation profile of the trip and eheat/AC. By using elevation data for your route (as well as climate setting and temperature) I have some hope!
Mountains eats through the SoC real fast, even with regen going down again.

Darren Palmer is the best. I literally would not have my First Edition if he did not intervene on my behalf. This is all such great news!

 

[ChasingCoral]

Yes, this is what caught my attention. We tease a lot here about the GOM (Guess-O-Meter), right? I heard Darren Palmer with Ford say the MME now has the tech to more accurately project your range when trip planning. Impressive. Say you have been driving conservatively around town for the last month, but now you want to plan a trip using the Ford Nav system. If I understand it right, the MME should now be able to predict the range you could realistically expect on your trip. Of course, the computer can not predict how fast you intend to drive on the interstate, so I assume it predicts based on the speed limit (plus 10 perhaps?) He said that tech is available now in the MME. Time to put it to the test.

They have had this all along. That's why I posted the thread about don't trust the GOM. The Navigation works great and predicts your range very well.

I can't charge at home, I rely exclusively on DCFC. I usually go to 82/83%, I use 'greenlots' which have a max of 50KW rate (get around 42KW).

How slowly do you poop

It doesn't matter. We will soon be able to poop slower ? ?

 

[Maric]

Yeah, this was a good listen and confirms what I hoped to happen and that's as they get more empirical data then we'll see more software updates. So, faster charging speeds are coming, I expect range increases as well as performance increases as well. I thought it was interesting if I heard it correctly is that they rolled out the GT before it was fully performance ready and that the October presser will be the car in it's finished form. So does that mean an OTA for better top end for the GT? We'll see. Hope to see it on the Premium as well.

Darren did say range increase is coming as well.

For sure! It's good news that the cliff is being moved and the charge curve is going to be changed.

Darren's comments about the current DC charging characteristics were very interesting. The way I understood it was that Ford was aiming for two things in a high-powered charging session when the car first came out:

• Give owners the best conservative 15 minutes of charging possible.
• 40 minutes to go 10% to 80%.

Today, 15 minutes on a HPC will give owners 30% SoC and if it takes you 50 minutes to get back to your car, you'll be at 81%.

This is all slated to change.

I hope Darren see's my message and I'll listen to the podcast later, but...I really hope they don't get too overly ambitious on the range front.

Everyone who bought the Mach-E paid for a certain expected advertised range. Anything more/extra, if it even comes with any miniscule 'risk' of fire danger, just isn't worth it.

I'm here (Mach-E on order) as a current owner of the Bolt EV in the process of a buyback from GM. If folks haven't heard, apparently, they just now advised folks to not park within 50 feet of anyone or any structures. It's a mess. I think the Bolt EV had maybe a 5% battery buffer.

That said, since the Mach-E ALSO uses an LG battery, are there any resources/references people know of on how similar/different this battery is vs. the Bolt EV?

Has anybody ever figured out the optimum charging schedule for battery health? I try to live between 20 and 80% and I only charge maybe 2x per week. Is that good, or should I be charging more frequently to stay between 50 and 80% I kinda assumed that the less I charge, the better.

Set max charge to 80%, charge every day. 80% on the mach E is roughly 3.9V and battery research shows no damage to batteries at 3.9V, past 3.9V is damaging to lithium batteries.
A 10-20% charge every day is easier on the battery than a 40-60% charge every other day.

When they rate batteries they do an extrapolated charge cycle which means roughly that if you charge your car from 60-80% every day, thats the same as charging your car from 0-100% every 5 days. Modern lithium batteries are rated to around 800-1000 cycles. a 60-80% charge every day will give you something like 1600-2000 cycles out of the battery.

So in short, charge every day, limit max charge to 80%.

What are you counting as a charge cycle?

Soon. Imminently. Shortly. Quickly. Speedily….. Q2-2021ishly.

BlueCruise was Q3. Q3 ends on 9/30, 13 days from now. Ford is famous for promising and then missing deadlines. I just drove close to 3,000 miles roundtrip, and BlueCruise would have been nice.

I got 1.6, then 1.4. However I cannot turn on SecuriAlert. I plan on visiting the dealer next week to get the noisy charging fixed and maybe that will update all modules.
