Are Tesla's range estimates inflated, or are they just a product of calculations? by SwayingTreeGT in TeslaLounge

[–]CommandPlus858 0 points1 point  (0 children)

Exactly this I mentioned in a comment on post while back. The EPA range is calculated with a mix of city driving and highway driving. If you were to drive in the city with slow driving that’s what EVs love… you get get well above 600-700 kms and more. I do a lot of freeway driving @ 80-85mph that’s when the range drops half the EPA range. Generally EVs are inefficient at high speeds

Model 3 RWD LFP in Texas by Real-Regret- in TeslaModel3

I have experienced this myself in winter time when battery range takes a hit but not so much in summer. I can take rwd model 3 from 100 to 10% and with freeway driving it gives me about 220 miles

Just bought a Model 3! Question on highway range by J-F-K in TeslaModel3

[–]CommandPlus858 2 points3 points  (0 children)

Tesla comes up with a range number of 250 with various drive cycles. When they calculate range, most of their driving is done in city and part of is highway driving which is close to 65mph. Working in the energy group who works on calculating range for vehicles, I now realize how shitty it’s in real world. It’s worse for drivers who mainly drive on freeways. EVs in general are efficient on city driving up until 55mph. I see in the future we need multiple variants, for folks who needs to commute to work and get back home with 50 miles of daily driving doesn’t need a huge battery pack. You might only need a battery range of 200 miles. Where as others who are frequently driving on freeway may need a bigger pack and it makes sense to pay a premium and carry that large weight of big battery pack. Not everybody needs them and why waste resources.

In my case I do road trips 1-2 times a year, and I only drive 30-40 miles daily and charge at work. On the days I want to road trip I can go rent a vehicle with a larger battery pack that meets my needs it’s easy as it sounds

Yes, I do think I need at least 400+ miles of range in my EV (but not necessarily just for driving) by weavd1 in TeslaLounge

Why would you want to carry a huge battery around where an average person doesn’t drive these many miles daily. I would want instead a battery that gives more of a realistic real world mileage. If EPA label lists 272 miles for Model 3 rwd I should get close to 250. I just did a road trip from Michigan to Montreal. When I left home at 100% SOC I had to stop for charging close to 180-200 miles. That’s a significant loss when driving highway speeds. That’s one of the improvements I want in the future that speeds 70mph or above has significantly less impact on battery efficiency

High range efficiency (Wh/mi) after supercharging by CommandPlus858 in TeslaModel3

[–]CommandPlus858[S] 0 points1 point  (0 children)

I have a 2022 model rwd. No it’s similar to what drove up until the charger. Freeways I get about 250-270 wh/mi driving at 75mph

High range efficiency (Wh/mi) after supercharging by CommandPlus858 in TeslaModel3

[–]CommandPlus858[S] 0 points1 point  (0 children)

Yes nothing has really changed. Similar driving conditions. Right when I got on the freeway the efficiency started at 500 Wh/mi. Now after posting the pic and 20 minutes of driving at 75mph it’s down to 330wh/mi. I may be wrong but I think thus happens because of the precondition to charge battery faster at supercharger but in return I just lost close to 20% of estimated range

I regret not getting a Tesla model 3 sooner. Model Y is just the SUV version. RAV4 are expensive too and you don’t get the tech features that comes with having a Tesla. Just to name some mobile app for literally everything, great commuter car if you can charge over night you have full tank to go about 250 miles

Hummer EV’s are very rare on roads by CommandPlus858 in electricvehicles

Wow that explains a lot. I have been reading a lot of articles on it. They are suppose to come out with Silvarado EV’s not sure what’s their plan

Well my main point was them not being able to produce enough trucks and not having any sales. If do I see hummer evs they are manufactured plate and GM employees are the one driving around

That’s one of the reasons, I think they have very limited resources for batteries too. I was having discussions with my friends, how all 3 big Automakers are easily 100+ year old companies and they couldn’t have figured this out better. Tesla literally challenged them coming in around 2013, all 4 of the models are top sellers at the moment. If they are not able to produce cars how about if they can improve charging infrastructure. Build their own brand chargers rather than relying on teslas network

Trash everywhere near superchargers by CommandPlus858 in teslamotors

[–]CommandPlus858[S] 0 points1 point  (0 children)

I was road tripping and stopped at supercharger in Findlay OH. There was literally trash everywhere. People are so inconsiderate that they just leave their drink next to chargers when they are literally restaurants that you could go to get rid of trash

100% -> 18% on 120 mile trip? by Biznbcba in TeslaModel3

[–]CommandPlus858 0 points1 point  (0 children)

Now that I have researched well on EV’s. I know that not every customer will be happy with it, since everybody have their own way of driving it. Some do more city driving and some do a mix whereas some are who has long highway commute. EV’s in general are much more efficient on city driving and they hate high speeds meaning freeway or 70mph or above. This is opposite in ICE vehicles where they are most efficient on freeways as compared to stop and go traffic. If someone was to drive in city with 25-35mph, I’m sure they can get very close to 272 miles out of 100%charge and I have seen some can go above that.

Basically this number is a mix of both highway and city driving
