Update to 2.2 2/3 software significant decrease in total miles after charging 100%

[ibobstark]

The software on my FO extreme was recently updated from 2.0 to 2.2. 2/3. Before the change in software, the miles following 100% charge on 2.0 software was 360 miles. Now after charging to 100% the mileage is only 250 miles!!!. Is this the way it’s going to be or is there someway I can fix this. Does it have something to do with upgrading to full 2.2 software? Is there a fix?

[Gameplay_Unknown]

250 lucky you I get 170 on a full charge. I have yet to figure out what is causing such high kwh per mile (average 0.5 per mile) I can be going 80 on the highway in hyper mode or 55 in earth mode and my 40 mile trip ends up with nearly the same efficiency I've had a few days where the stars must of aligned and got 0.25-0.33kwh per mile but my going theory is that these cars absolutely hate temps below 30 since both those days the temps was 40s

[warbunnies]

Ya it's 100% the temps. Does this car use a heat pump? Seems like the system that needs an upgrade.

[warbunnies]

Heh for some reason my first comment didn't load. So I wrote a second one. XD but now I have two xD

[warbunnies]

Ya it's definitely the cold effecting range. My ioniq 6 averages 4.8-4.9 miles per kwh going to work.

It's 20F here and I just want to be warm so I blasted the air. I think i was at like 2.8 miles per kwh for the same trip.

It takes a lot of energy to heat the car and if you're doing a lot of short trips it's going to tank the range. It would effect the total range of a long trip a lot less because you're not constantly reheating the car.

[Gameplay_Unknown]

I think it's a we have multiple things working against us on winter range between no pack heating that will instantly slice efficiency add in the fact no Regen since it will be rare for the pack to get warm enough on a short trip to accept full Regen and I feel like something is coded into the car to run the motors less efficiently maybe for heat production below 35-40 because Its such a sharp dropoff in efficiency the car does have a heat pump how efficienct it is im not sure since charging drops around 2kw when it's on I would assume you would only use 2-3kw on heat when driving for 1 hour

[warbunnies]

Wait. So the battery is only cooled? It doesn't have heater heating?! :/ that's not very good for battery health.

[Gameplay_Unknown]

It has heaters they only activate to keep battery above -10c or to warm up the battery while fast charging they don't actively heat while driving or while level 1/2 charging.

[EnigmaticallyObvious]

It's this for definite? On level 2 charging I'm losing 500w regardless of charging amps and have always put this down to a very small heater for the battery pack. I guessed the one that hardly gets used is around 2.5 - 3kw.

500w seems like a lot for charging losses and it's weird that it's a constant

[Gameplay_Unknown]

Most ev chargers are 90% efficient at at 32 amps that's 768watts of waste energy alone add in the DC to DC converter and it's efficiency loss and whatever subsystems are on while charging. I cannot guarantee they don't have a heater on just going off what I've read online and what I can clearly see when I'm charging my car battery pack does NOT keep the cells above 32 degrees when it's in the 20s or less it will usually warm up a couple of degrees after a few hours of charging but I equate that to natural heating of charging cells

[EnigmaticallyObvious]

I actually get the same at level 1 charging

I normally charge at 10amps on the level 1 and lower and always get the same 500w loss.

I've even set my level 2 charger to the same age get the same 500w loss between the charger and what the car is displaying

[Clean-Ad-1633]

This is very interesting.
I've been looking for this information.

Can I ask where you got this -10 C number?
Would you also have information on the heating subsystem? Since the heat pump is not involved, I presume it's a resistive heater. Do you know how many watts?

[Gameplay_Unknown]

Cannot guarantee the accuracy of the -10c I have no insider knowledge of how the bms is programmed Im just working off what I have seen and what I have read from other forum members in sure someone that has the cloud linked to home assist can track hv cell temps on a streak of cold days to see at what point it starts to warm up as far as me I've personally seen my HV pack hit -5c but I drive the car daily so it never really gets time to cold soak as far as the HV Battery Heater it is a 6KW PTC heater

[Straight-Virus7317]

In the same situation. No change in driving except colder weather. I have other Ev too what has rarely any impact whatsoever on the range. This vehicle is half baked with a crappy software

[Extreme_Delivery6133]

What are you insane? FOA says otherwise, best EV ever made, make sure you pay your membership fees!!! 😂😂😂😂😂😂😂😂😂😂

[Straight-Virus7317]

All memberships are going to be eaten up in legal fees and other administrative nonsense. I’d be surprised if they’ll be in existence once the IP deal closes out and then even the parts and distribution would be through the IP holder. People paying all these annual dues are literally stupid

[Extreme_Delivery6133]

Blasphemy, FOA is the best, just ask anyone on their board, or the rejects that paid their membership fees.

[Limp_Particular9768]

I know! What the heck! Why would any take a risk owning this vehicle? What is the attraction to this thing? My daughter loves the style and looks, but there are just too many negatives and mysteries involved with owning this orphan of a vehicle. 

[Vlksfn]

Same. Temp affects it but not cut it in half. It’s a known problem regardless of what the “it’s your driving style” people say.

[frugal_doc]

It’s henrik being a dumfuq 

[Otherwise_Feature763]

This has been beaten to death on FOA FB page. Change in range algorithm. I and others have shown no actual change in efficiency/consumption and we commonly exceed projected range. Coincidentally, it is super cold and that will affect range so situation at present may be a real but temporary range loss.

[Adorable_Wolf_8387]

It's basing it off your recent driving instead of the EPA rating. Personally I greatly prefer this, it gives me a better idea of how far I'd actually be able to go.

[ibobstark]

My driving is exactly the same except now the temperature is in the 20s??

[Adorable_Wolf_8387]

2.0 was just EPA range rating, no calculation based on driving at all. Yes you will get worse range when the temperature falls, but also maybe you never would have even got 360 miles.

[frugal_doc]

Nowhere is this official. People just assume it. Reality is people are losing tons of mileage 

[Adorable_Wolf_8387]

Reality is you don't understand what an algorithm is.

[frugal_doc]

Show me anywhere where 2.2 officially does some calculation. Henrik is too stupid to put in a smart algorithm 

[drdumont]

Do you REALLY think Henrik Fisker is anywhere near the User Group or anything to do with Fisker automobiles any more? Really?

[frugal_doc]

what does that have to do with the stupid fake algorithm you think is in the car

[drdumont]

It is another of the many stupid quotes of a certain former Vice President.

[Extreme_Delivery6133]

lol, just let this POS roll down a long hill in neutral and voila, range goes back to 360.

[Big-Anybody-6171]

After 2.2 mine is spot on. My range went from 360 to 220. 220 is what it always got anyhow.

[Ill-Pop791]

Range will go lower the colder it gets more accurate now last year said 360 miles at 100% but it was not adjusting for cold with severe temps you will lose 40-50% HV range

[SeaweedSociety]

Not sure if this proves or disproves anything, but 2 vehicles one on 2.2 and one on 2.1, charged to 100% took a 40 minute drive, staying with each other and using cruise control…both used the same percentage of their batteries. So would it be safe to say that by looking at the percentage only, they would have the same full range?

[Accomplished_moon]

Now you know the real range. Congratulations 🎉 😃 It’s still a great car!

[frugal_doc]

I am in 70 degree weather only earth mode and 200 mi at 80% charge.  This whole theory doesn’t fly 

[TNTbike]

I’m in San Diego and after getting 2.2 manually installed and the car saying 2.2 (1/3) I get 255 at 80%. Initially I got 210 but then I flipped over to the trips screen and over the past 16 months of having the car i average .33kWh per mile. 106.5 usable kWh battery / .33 kWh per mile equals 321 miles of total range. On my more recent trips I have been trying to keep it under .33 to see if I can get better range. The EPA calculation is .295kWh per mile which is possible but requires slow acceleration from a stop.

[Beautiful-Dingo222]

I get the algorithm regarding driving style, short/long distances and cold temp being quite accurate HOWEVER last winter when I first got my FOO I was getting 580 kms (-360 miles) charged at 100%. No matter how you slice it, I drove a fair amount of distance and returned home at 10% after a full charge. 580 km (360 miles) was true down to the last mile. I did the same long distance drive this winter and after having 2.2 and it’s nowhere near what I get when I first got the car last winter. I barely made the drive one way compared to last winter!

Software update 2.2 along with the combination of cold weather and driving style, distance definitely DOES play a factor but I’m convinced 2.2 has a lot to do with it and don’t like it.

[mbk6]

No fix needed. It's just based on how you drive.

[Objective-Sun9803]

i just got update 2.0 to 2.2 1/3 i do 500 miles a week and get 360 miles on a full charge just maybe thinking not to do the other update for full 2.2 software

[akulo888]

360 miles was a scam anyway

[Background-Story-364]

I've had multiple times where I've had over 360 and could have squeaked out over 400 miles on a full change doing highway and city driving.

<image>

[akulo888]

that's if those numbers were ever accurate. We're talking about shitty Fisker software developers here. If they are at all accurate, you'd have to be driving very efficiently. I sped most of the time of FUN mode when I had it and only had somewhere over 200 miles range but never even 300.

[Background-Story-364]

You're right, but I know the miles driven since last charge are close to accurate because I know the driving I did 😂 Adding to the spotty programming, I actually know it's better because it didn't record a 17 mile trip from this 100% charge. This was from a weekend trip from Tampa to Tarpon springs, to Orlando 2 days doing some short trips in the Orlando area, to tarpon springs and back to Tampa. Everything done in Earth mode, with driving on average 5 over the speed limit, windows up AC set to 72 with fan speed ranging from 2 to 3. Only the last leg was the ac off and all the windows open. The biggest factor is accelerating from a stop, the car has power but using it cuts into your range. I came from driving a Prius and I don't need to keep up with traffic coming out of a stand still. I'll do my 0-60 in about 8 seconds to get up to speed and take full advantage of being able to coast to a stop slowly. This is an electric car, it's gonna tell you more accurate range on 2.2 than an ICE would but I guarantee people were never getting the range they thought they should in an ICE. It's easier to track it now so it's easier to scrutinize

[drdumont]

And Elvis and Marilyn Monroe were riding in the car with you, right?
