Extended Range 320 Miles???

[ATLJoker285]

That's called a Jedi Mind Trick.

You can reset the data all you want. You're wasting time and effort. It will always be wrong. It used to be spot on accurate in the beginning, but it was changed to kowtow to the people that complained.

It's still closer to what you can expect vs long term data. That's typical of any machinery. I was just making sure the OP knew it existed. What anyone does with it is up to them.

I did caveat it with "until you start driving". We can expect different results under different conditions (weather, city vs highway, etc)

I created this little matrix to show the ESTIMATED effect of temperature and effect of avg speed on range. I hope it helps. As Zprime stated... if you need to get a certain mileage on a trip. Monitor your MPK (131 kWh battery so, ever 10% you use is 13.1 kwh) as you go and do the math to figure out if you will get there or need to slow down to maximize efficiency. I'll go as far as resetting one of trip monitors once I get on the highway so my MPK is not polluted by any city driving that was done to get to the predominate interstate or highway.

I keep a spreadsheet for my Lariat ER tracking the date of charge, miles driven since last charge and kWh added. My calculated mi/kWh at different ambient temperatures is pretty close to the values in your matrix.

Yeah, my Ram didn’t get 15/22 either.

It comes as a surprise to most new EV drivers that unlike their ICE vehicles, which get better fuel economy at steady highspeed on the highway than in city driving, EVs are LESS efficient at steady highspeed highway driving, than in the city. The reason is regenerative braking in the EV (helps its efficiency) vs. the extra gasoline required for accelerating in stop-and-go city traffic.

If you drive a lot of city driving you will see numbers of close to 400 miles on the guess a meter.
On the highway - no wind - warm temperatures - not going over 70 mph - you should see between 2.0 -2.4 miles per kWh
Once any of those variables are changed it only goes down from there
You will get good with math in your head.
13 kWh / 10% of battery.

I wish that our Lightnings’ GOM Range display had a setting that (instead of the mysterious “guess” range that is the bane of so many on this forum) would display a “dynamic“ range based upon the instantaneous mi/kWh x the remaining battery kWh. On highway, you would know immediately how to adjust your driving in order to have enough range to get to the next charger (if you have 57 miles to go, drive so that your “dynamic range” number stays at or above 67mi, or whatever arrival safety factor you can tolerate).

100%, I also would much prefer the stored energy gauge be displayed in kWh not percentage. It is mind boggling to me that they measure efficiency by m/kwh, but then measure capacity by %

In these massive computers on wheels, no reason we can't have both. Imagine that, options.

I can't imagine these weren't discussed at length by highly-paid people. Then they decide on this?? They CAN'T be driving Lightnings (or MME) full time.

 

[Ventorum94]

They CAN'T be driving Lightnings (or MME) full time.

It’s as though everything was geared toward the never-before EV owner, rather than the needs of the same driver after 6 months experience in their Lightning or MME.

I debated about posting but I’ll say I’ve nearly 34,000 miles on my LT ER of which ~32,000 are commute of 100 miles a day. My long term average is 2.4-2.5 mi/kWh. My good weather daily burn is about ~30 KW and winter about ~42 kW. The real deal is the nearest open range freeways are 2.5-3.5 hours away thus averaging 60-80 is a laugher. We live in US ruralandia where 50 is a good average on winding exposed coastal roads. On a recent drive I pulled (on a 100% charge) 296 miles on a round-trip and still had nearly 60 miles left. But that’s what a mild warm day heavy summer traffic coastal road will do. A winter windy headwind afternoon will drop me to 2.2 mi/kWh just like that.

I am reposting this below from another "lower mileage than expected" thread in September:

As a wise older engineer once told me: "Electricity is not a liquid. You can measure water or gasoline or diesel or kerosene or coal almost exactly, by volume and by weight. Stored electricity can only be measured by its potential to do work".

When I switched to EV driving years later, I began to understand what that old engineer had shared with me.

Hence, the Guess-o-Meter on our EV vehicles. It tries to estimate the potential to do work by our vehicle-stored electricity. It's always an ever-changing estimate and not an actual measure of physical weight or volume. It's not wrong in what it tries to do... we users have to un-train ourselves from a lifetime habit of measuring fuel by physical attributes (gallons / liters / pounds etc.) and then our GOMs might become more useful to us. -- end of quote--

Hence, the EV battery's "potential to do work" is an estimate of events going forward at that point in time. If the route begins to climb at that point non-stop for the next 300 miles, the GOM estimate will be terribly short. If the route will begin to descend gradually non-stop for the next 300 miles, the GOM estimate will of course be fantastically extended as the drive's minutes go by. If the OP driver switches out and lets my 17-year old son take the wheel of his Lightning, the GOM estimate of course will again fall terribly short. Note: my son is now quite a bit older than 17, and I am very thankful

So once again, the GOM indicates the battery's estimate for how far its currently stored potential to do work will last, based purely on past factors. It is not and cannot be an actual standardized measure of a physical attribute like weight or volume (i.e. "gallons"). Actually, considering the difficulty of directly measuring a constantly electric charge I am kind of amazed that the GOM works as well as it does.

Hope this is a useful way of seeing our GOMs.

390+ miles for me

Temperature makes a huge difference.
I got home yesterday at 34 degrees showing 50% charge and 120 mile range on my '23 ER. Heat was set to 65 and seat and steering wheel heat were on.
Earlier on the home charger it showed 219 at 80% in the AM but then I did a Trip Departure prep 20 minutes ahead of time and range estimate went up to 249. I could not do a trip departure warm up returning 7 hrs later (30 miles each way).
In the summer I was showing 327 range at 100% and 26x at 80%.

Have you compared the displayed range to what you actually get? Once I did that, I started ignoring the GOM completely.

I'm too chicken to push it to the limit. I almost always recharge at 30% or higher. At home I rarely drop below 50%.

The great thing about having an EV is that I skip the gas stations and when I get home I just plug in and walk away. No more range anxiety in a 60+ mile radius.

Ford advertising a 320-mile range on Lightning:


Highway range in the summer: 270 miles
In the winter: -45% = 149 miles
At 70% degradation (the most the battery will degrade under warranty) = 104 miles

104 miles should be how this truck is advertised. This should be the rule across the board.

Ford should be ashamed. And so should GM. And Tesla. And practically everyone except the Germans who tend to consistently underpromise and overdeliver on range.
