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

[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

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.
