I think itˋs broken. You should buy a new one.

 

Will they replace?

I checked on Safety and Emission Recalls | BMW USA, and with dealer too, there is no battery recalls for my car.

 

There is probably nothing wrong with the car, and how you use it. Outside temp (27 celsius?) can be part of the answer, what have you inside ?

What kind of driving short/long/commuter/city ?
Do you use preconditioning.
Also important to use navigator and enter trip - to get correct range estimat.

 

It's celsius. Inside I generally keep 20 degree Celsius. I do small commutes ( ~ 10-20 miles each trip). I don't use pre-conditioning.

 

How many KWh have you charged in total so far?
What is the total mileage you have?

 

Total Charged 75KWh and 61% was current charge (i.e. 39% consumed ~ 31KWh), total consumption from date of vehicle purchased: 106 KWh, Total miles: 329. Total miles per KWh = 3.10

 

And do not charge above 80% if you don‘t need the extra range.
If you can not bring the capacity back below 80% within 4-6 hours,
it will kill the health of your battery over time.

 

I picked up my car on Saturday and spent all of Saturday and Sunday driving around testing the acceleration in “sport mode.” The car was estimating ~170 miles range on ~90% charge.

Yesterday and today I’ve been driving to and from work in “comfort mode” and using “normal” acceleration and following highway speeds. The car is now estimating ~215 miles range on ~75% charge.

The car takes into account your driving habits to give you an estimated mile range. If you were like me and played around with the car the first few days, the estimated mile range will not be accurate. Give it time to adjust to your routine driving habits

 

When I'm having short trips only, range suffers because interior needs to be cooled for short trip only, precondition or while driving. Even more so the coming days as we have 30+ deg C the next few days here. So on short trips, that takes a huge chunk from the range. Yesterday I had a long trip, 350 km, and now it says 446km at 80% SoC in the app.

As others said, only charge beyond 80% if you need it for the next trip. And after a few longer trips the car adjusts to your driving habits.

 

Plug it in and climatize while it’s plugged in?

 

I've come to the conclusion I will never actually know my range unless I run it down to 0%. There were times yesterday on the highway if I would have kept driving the way I was driving, all the settings the same, I would have done 350 miles. But of course, I changed a setting, I put the air up two degrees, then my range dropped by about 25 miles, then I put the fan down a notch and it increased 12 miles . I have no idea how I'm going to plan a trip with this thing, lol.

Carefully Elle, carefully.

 

I've only had mine for a few days and it's my first EV, but I understand why estimated range is often called a "guess-o-meter". It varies wildly depending on your driving style. Sitting in your garage for 20 minutes, setting up your car with the A/C running even affects it. Yesterday...

1. Sitting at 80% in my garage, 250 miles.
2. Take a neighbor for a spirited 4-5 mile ride, return with 78%, now 212 miles.
3. Charged back up to 80%, 220 miles.
4. Drive to dinner on Comfort, 45-70mph. 35 miles there and back. Arrive home with 67% and 205 miles.
5. It's charging now at 70% on the way to 80% and reports 239 miles.

Point is, it varies.

I've also noticed that initial cooling of the interior on a hot day really affects the GOM. Range drops immediately and dramatically as the AC is blasting until interior temp is reached. Then it slowly "catches up" to about where it was before relative to miles actually traveled. Yeah, I can see how important preconditioning is.

 

I think it is Tesla that has the guess-o-meter.
A few years ago driving down 300 meters, we discovered that it only is able to show 999 kilometer range in the Model S.

On the BMW i3 if you enter your target in the navigator, it is very accurate. When I am driving to the limit of the range, I trust it so that I sometimes arrives with less than 3 km range left, by switching to Eco Pro and EcoPro+ when my range goes below target. I actually expect the i4 to be at least as accurate as the i3, and that it will improve with newer sw updates.

 

Can we once and for all sort through the misinformation about B and auto mode as being the most efficient. My dealer has confirmed that when using the brake pedal it will regen as much as it can before using physical discs and pads. If so, you can be just as efficient in any regen mode if you anticipate the road ahead properly.

Is this correct or not . I have just driven a Genisis with, like, tesla, doesn't regen at all when using the brake pedal. Ie. It does not have blended brakes like my polestar does. Bit of a deal breaker for me as I have 1 pedal driving. It is ok around town but not OK when gunning it down country lanes.

Please only respond if you know factual information. If the i4 doesn't blend brakes the n I need to cancel my order on Monday because I have a sept build on my m50.

Quoted the manual above. Further:

Starting page 117: Energy-saving driving and maximizing the range

Then page 124: Strength of recuperative braking In selector lever position B, the energy recovery is high and the deceleration is strong. For driving in selector lever position D, the strength of recuperative braking can be adjusted via iDrive. ▷ Depending on the equipment adaptive energy recovery: energy recovery and decel-eration are automatically adapted to the respective driving situation. Adaptive recuperation, recuperative braking, refer to page 279. ▷ High energy recovery: the vehicle deceler-ates fast, more energy is returned to the high-voltage battery. ▷ Average energy recovery. ▷ Low energy recovery: the vehicle deceler-ates more slowly, less energy is returned to the high-voltage battery.

Note that the High/Med/Low is for regen in D mode; using the brake pedal in D mode creates regen until the brake pedal force exceeds what’s possible from regen and then it engages the physical brake pads/rotors.

 

So, if I interpret this correctly, the brake pedal will regen to max before using traditional friction brakes.

 

The electric motor will regen before you need to use traditional brakes. If you can get used to one pedal driving in B mode you almost never need to use traditional brakes so you brake pads will last forever

 

When I got my car last week dealer charged to 100% and range was 246m. Driven about 140 miles and just charged to 81% and range is 231m

 

No. This is wrong too. If you use the brake pedal you do use regen if it is a blended braking system. Unfortunately in the bmw you can't fully turn off one pedal driving, you can only reduce the feel of it. It doesn't matter which setting you have it set to, the amount of regen is exactly the same (you might press the brake pedal more if one pedal is set to low but you still recoup exactly the same kinetic energy). Ideally, you could switch off opd and freewheel (which is far more efficient than regen) but you can't on this car. You can very carefully position the accelerator to achieve freewheeling but it is more effort than simply taking your foot off the accelerator. All of the above is probably irrelevant to most people because they enjoy opd. Just not me.

 

that make sense to me, it's not the amount of energy recouped, that is the same, but what you actually have to do to recoup it. like press on the brake harder, or not much at all, as in B mode

EDIT: maybe I should be more clear on what I mean as "the same" meaning if in B mode it will recoup a certain amount of energy, but if in Adaptive mode and I put the breaks on hard, like in B mode, it will recoup the same amount of energy. At least I think thats what I mean by "the same" B mode doesn't magically recoup more energy

 

So I'm preparing for my first "road trip" without umbilical cord! It is an overnighter to Central Florida and there is no advertised charging there but perhaps a level 2 enroute or slightly off route. I've slow charged my i4 40e at 12 amps (3kw/h) to 100% so I leave full up. My range is showing as 270 miles and one way is about 128 miles, plus I expect a few additional miles at location, so roundtrip approx 260-265 miles or so, so I'm uncomfortably at the end of range. But I truly expect my actual range to improve based on type of road and speeds I'll be driving, so I'm expecting to get closer to 300 miles plus.

My friend has a 50amp RV plug at his house which is available should I need it. My plan is to not recharge at all unless my return indicates I'm really cutting it too close.

An important point here is my friend (best friend from college) is anti EV big time. He was laughing that my "Golf Cart" might need to be recharged to get back home. So I have to save a bit of face as I have tried to explain to him that ICE are soon to be dinosaurs, like it or not.

If I have 50% left when I'm ready to depart, I'll be fine, otherwise I may have to add a few kwhs at my friends and listen to his crap for years to come.

 

Ah!

A couple launch control starts with him in return for a bit of recharge? That’s how I’d play it!

 

I think a lot of the confusion about one-pedal driving and B mode efficiency comes from years of Tesla experience. Tesla uses permanent magnets in its motors, which do not allow free-wheeling. Minimal power has to be continuously applied to the motors when coasting. So in a Tesla trains the driver not to attempt to coast by providing one-pedal driving - no coasting, just regeneration. The BMW motor does not have this restriction and so the motor can truly free-wheel.

Coasting is more efficient than regeneration for the i4 but not for Tesla's and other EV's using permanent magnets. The reason is that regeneration does not recapture the total amount of energy. Consider if your i4 could coast 500m before coming a complete stop. If you applied regeneration, you would stop short of 500m, say for arguments sake 250m. You will not have regenerated enough electricity to then drive under power the remaining 250m. Some of that energy will be lost to the regeneration process.

The adaptive regeneration enables the coasting when in D mode. But the car only coasts when there are no obstructions ahead or other reasons to slow down such as upcoming turns. If you are driving in town which usually means traffic around you, frequent turns, etc, B mode makes sense because you hardly ever have an opportunity to coast.

Blended braking is always on. In D mode, when you press the brake pedal, the regeneration kicks in first. However, if you push harder the brake pedal because you require more braking force, the physical brakes kick in. In B mode when you let off the accelerator, regeneration automatically starts, but physical brakes are not engaged until you step on the brake pedal with enough force to exceed the current braking force of the regeneration, i.e. you slow down faster.

D mode with adaptive regeneration for highways and B mode for in town or when carving the twisty's.

As long as you aren't driving in circles west of Lake Okeechobee, there's a place to plug in.

Haha! That is exactly where I have to go! From Southeast Florida (FLL) up US 27 to those lakes just South of Sebring. That Charger in Sebring is a Nissan Dealership but I'm not going that far North. In the town of Okeechobee they have installed four (4) FP&L (Charge Point) Level 3s. I think CCS, 50KW? I've already registered so that will be one of my back-up options.

No EA anywhere near this area unless I head to the East Coast.

I'm actually pretty confident this i4 will make this trip safely on a single charge. If it can't I may start looking for something else!

 

But I have to say this has really changed the whole concept of planning for a road trip for me! My 328d will get me to South Carolina on a single tank, almost 700 miles!

What have I done?

 

The EV is a paradigm shift. We should treat it as what it is, not try to sugarcoat it for others to like and then be disappointed for not being what we portrayed it to be.
The only objective disadvantage of a decent range ev like the i4 is the charging speed and we should not lie about it. The advantages on the other hand are numerous, one of which is that you have the fuel available at home or anywhere. That includes your friend's house. He'll be amazed that the amount you need to get back home won't even show up on his bill.
There are more things to say but all in all you should not try to hide the truth about EVs. Embrace them for the right reasons

 

I just found my 3rd option, which will be my "last resort". Charge Point has some Level 2s (6kw) in Belle Grade just South of Lake Okeechobee and right on my route. Might be slow but if I need any it will just be a little bit to get back home. This is adding a whole new dimension to car travel!

In all honesty the best answer is to just suck it up and take a little charge from my friends RV outlet. Maybe I'll just sneak out when he is asleep!

Hopefully he doesn't have it locked!

So I left home yesterday afternoon with about 97%. I had to run an errand quickly so didn't have 100%. I had to go 128 miles one way and it noticed how my miles I had left were slowly increasing or just not changing as I drove on for quite a while. I guess my previous drives were not so efficient but this one was and my miles/kwh started to increase to the 3.4 range. Eventually I was in the 3.6-3.7 miles/kwh which well exceeded my expectations of 3.3. So that was a pleasant surprise, gave me more range. In the end I think it was very close to 300 miles for a full charge driving about 60-70mph with some slower sections. Full AC as very warm in the low 90's. I made it to a party then back to my friend's house and I had about 50% showing and a range of about 150 miles. My return was about 120 miles but we wanted to drive around the area some so I broker down and connect to my friend's RV outlet and added 20% (back up to 70%) or 18kwh, in about 2 hours using my BMW charger. We did our drive around the area and then finally left with about 60% and more than enough to get back home. I arrived with 17% and some 45 miles.

So, the range anxiety is real, but there are a lot of possible charging options out there. But some may not be what you think when you get to them, as one FPL Evolution (Charge Point) advertised as Free is actually not at all available for the public. Destination charging is by far the best solution in my opinion. You don't waste your time and can charge while you sleep, eat, shop, etc...

My friend was impressed by the i4, took him for a ride, but he is convinced more than ever that he will never own an EV. He has his own issues and really cant be bothered by trying to figure out when and where he can recharge a EV. He has to travel a lot in his vehicle and doesnt have much warning of when, where he has to go, and often is in remote areas. I pointed out that the vast majority of car owners park their cars in their garage at night 90+% of the time where it is just so easy to recharge at home.

I really enjoyed driving the i4, got to get comfortable with DAPP which actually worked quite well on the open road.

Looking forward to my next road trip which will be to Daytona Beach in September. This will be along I-95 where I know there are plenty of EA locations enroute. Now just need to figure out if I will have a destination charger!

 

Definitely call that 888 number and get better info on where exactly that one is? The mapped location doesn't seem very accurate.

 

So checked into it and indeed they are shown as free. This is the entrance to the Florida Crystals Sugar Mill and it appears it is some sort of a "Green" effort being done by them and FP&L, and they say it is free. Problem is I'm not sure if it is inside or outside of their main gate entrance, i.e. it may be free for their own vehicles, but not just anybody lost in the Everglades! I might just stop and have a quick look on my way up later this afternoon, to avoid any surprises.

Hey, all I know is my batteries are at 100% and I'm headed out on an adventure! I'll update how it goes. Fingers crossed!

 

Your friend is probably 50 percent correct : He will not have an EV before 2025 - by then range, cost and charging options will be so good that all people will prefer EV's as their daily driver.
Only showstopper could be that people cannot afford EV's since they cannot get any money for their ICE cars.

range anxiety is a good thing to have. IN the beginning it is a little bit stressfull, but after some time it will just be something to think about/plan: I have driven my i3, with half the battery size of the i4 for 3 years, 94000 km - never run out of battery (the nearest was driving 10 km after zero percent battery), but I have run out of fuel in my Gas cars many times.

Hey, the world was "flat" once too!

 

Like the very first post of this thread, with my i4 eDrive 40 with 19" wheels sitting in my garage it currently displays a 74% charge with a remaining mileage range at 173. This equates out, with a straight calc, of 234 miles at a 100% charge (which I am aware of is a no-no to charge to). Pretty much any charge and range reading while idle calculates out to ~234 miles at 100% charge. I will note that in driving in city & urban conditions my trip displays typically indicate I am getting 3.1 - 3.3 miles per kWh which would calculate out to a ~261 mile range (81.5 kWh x 3.2) which is a bit closer to EPA's 282 mile range. I am really curious what effect, at least in theory, the driving mode has on mileage range under, say, "ideal" conditions. I have found the posts in this thread that discuss the driving modes of interest, but there are so many variables it is difficult to determine what effect each driving mode under identical conditions has on mileage range (or miles per kWh). Nor, have I been able to find any kind of apple to apple comparison on this in spending hours of Googling time. Can anybody provide a link to what I am looking for? I know, nit-picky, but I am curious.

 

I think Eco Pro should make a difference since the HVAC is noticeably less cool. But AFAIK that’s the only affect. If you haven't seen it...

The GOM does weird things. I took a ~200 mile "sunday drive" yesterday. Started with 100% charge, ~320 mi estimated range. About a 50/50 mix of 75mph interstate and rural, 2-lane 50-60 mph back roads. No meaningful wind, 75-85F. Inbound, 80 miles from home I stopped at a 50kWh DC and did a 55%-69% charge in 18 minutes while grabbing a coffee. I arrived home with 50% SOC and plugged into my lowly 120V. Trip average, 4.1 mi/kWh. Check out these numbers...

Yeah, when I arrived home with 50% charge, 199 miles on the GOM. Sitting at 70% now with 270 miles. I've been extremely impressed with the range on the base 18", but even I don't expect 400 miles on a charge.

 

Wow, I'm getting just under 3.0 miles/kwh so far. I do have individual drives that might reach higher, 3.4-3.6, but my average in my first approx 1,000 miles is 3.0. Maybe I am driving too fast on the Highway, at 80mph and need to drop off a bit? Curious what's the difference between 70 & 80mph or say 75 vs 80mph.

I notice that most EVs show better city mileage than highway, and we know this is due to regeneration. So far I've not been doing that much city driving.

 

If you drive on a level highway you can watch the mi/kWh gauge. I have noticed that it will be good up to 70 mph, then drop off at higher speeds.

So to get range I set speed control to 68-70 mph (w or wo lane assist) and chill.

It is amazingly relaxing to go in the right lane just a bit slower than eveyone else. You avoid the stress of having to pass someone every 20 seconds.

on a long drive you may drive 10% longer but with 50% less effort

 

This is a fun story to read! Reminded me of planning a drive to see my mother in Jackson, Ms. and @M3HNGRY offered I could use his charger at his home as there arent any available public chargers in the area.

I'd do the same for Elle if/when she comes through my area!

3.35 miles per kWh !
Not excited by this stat. This is operating my 2022 i4 edrive 40 in Florida since April 7th. I now have 4,998 miles on the car and have charged the car 1494 kWH to date.
I suppose summer in Florida, A/C at all times, and occasional high speed highway driving are taking their toll on battery performance.
How are others doing in Florida, or other climates, interesting to hear what people in other areas are getting.
I drive in Comfort and B mode 99% of the time.

 

Sun Coast, I published all of my charging stats somewhere on here. I'm getting just about 3.0 Miles/kwh with 2,000 miles and about 2 months. I live in FLL area, so yes AC all the time. I've seen a trip or two that came in near 3.3 or 3.4, but my total since new is sitting right at 3.0. You're doing better than me so far. I have similar car, drive spirited. Dont really know what to say. I was expecting closer to 3.3 or 3.4, so I'm about 10% less than I expected.
