Thank you, glad you found it helpful and appreciate your support.

You’re welcome. Hope you love your new Ioniq!

Yes it is! Gives one lots of confidence in the longevity of the E-GMP battery

Yes I was surprised by the results and furthers my confidence in Hyundais eGMP battery tech. I was expecting about a 5% capacity loss which is what I experienced in my Tesla model S.

@@UpperWestEV People do complain about the E-GMP charging curve but there seems to be some solid science going on here. It will be very interesting to see the composition of the new Ioniq 5N batteries.

Glad you found it helpful!

Thanks for the great info, yes, definitely a well thought out car.

That’s great. Glad you’re getting such a wonderful range. On the Ioniq 5 there is a big difference between the efficiencies, 132mpgE city and 98 mpgE Highway.

I just posted something similar and thought it was my imagination until I read your post. Im getting better Kw per mile this summer than last. We will see how winter goes but at 34k miles Im not seeing any problems, just the opposite. There was a software upgrade for RWD. That could have helped.

2022 RWD no software updates, 75 mile trip, 65 mph, cruise control, AC, on Interstate flat and hilly, reported 4.2 miles per kWh. The higher efficiency= close to 50 additional miles. In my experience, 65 mph allows more consistency as to speed (changing speeds is less efficient) on the road. I used AUTO Regen middle level. Thanks.

Oh great thank you for sharing the extra information.

Hey, thanks for the kind words. Glad you found the video helpful, and you’re loving your Ioniq 5, it is been a great family car for us.

DC fast charging hurts batteries far less than anticipated a few years ago. What really hurts NMC LiPo batteries such as those used in Ioniq 5 is charging to 100%.

You are welcome. Thank you for the kind words.

Thanks for sharing, I was happy with the results.

Wonderful, Glad you are enjoying your EV6 and you found my results encouraging. Thanks for sharing

I have an EV6 AWD model and have had very little complaint about range . It is the "time to re-charge" that makes the difference to worry about distance.....I recharge overnight at home (240vlt) when needed~But Im under 10k miles so over time I can report more.

I understand where you are coming from but.... the efficiency, or rate of consumption, 3.5 mi./ kWh, was the same in both tests, but I was not able to go as many miles. If there had been a difference from wind or temperature the consumption rate would have been different. This was not a difference in efficiency but a difference in capacity.

​@Upper West EV well I wonder if you redid the test what the results would be 1% could be a rounding error. I know on the interstate if I run at 65 I am lucky to get 3 kwh I'd love to average that 3.5 you get.

Meaningless number but not meaningless test. This is what people want to see.

Glad you found the video informative, and definitely adventure out and try fast charging!

Hey, thanks for the question, I didn’t usually run the battery below 20% but it would happen a couple times a day while road tripping.

Agreed my result boosted my confidence in this battery system quite a bit.

I too noticed that the cars rated range was very sensitive to temperature. Thanks for the extra info.

Yes I was pretty happy with this result. We can’t get the MG4 here in the US

Hey, thanks appreciate the feedback, that’s my goal!

Thanks I felt the same way, confidence building.

@@UpperWestEV It's such a supremely amazing long distance cruiser, so comfortable!

You’re welcome, thanks for the encouraging words.

Yes, I was pleasantly surprised as well

Thanks yes, I was very happy with the results. My experience with my first two Teslas was that I saw about a 5% degradation after 30,000 miles which was one of the reasons why I wanted to do this test.

@@UpperWestEV Whatever the Koreans are cooking with their batteries is really working. I'm also looking forward to what BYD can cook up, their blade LFP batteries have really been impressive to me, can't wait for further improvements with that.

I read a little article on those blade LFP batteries does sound promising. I really like the LFP battery in my model 3

@@UpperWestEV The Funny thing is all Teslas, except for ones that are manufactured in the USA, use the blade batteries for their LFP model. The USA has an import ban on Chinese batteries.

Haha, well time will tell, but so far so good.

EVs aren't even usable yet. You know we all drive 28 hours a day 800 miles to work and back towing a trailer up hill both ways in the snow.

Your KZfaq name is Lemming so makes sense lol.

I agree, with my Model S, I saw about 5%, so was very pleased / surprised to get this result...

Hey, thanks for the encouragement! I don’t do a lot of driving when I’m home, so I set my car to charge to only 70% when at home and when on road trips I set it to DC fast charge to 90%. I know Hyundai recommends charging to 100% once a month. I believe it would be fine to charge the car to 80% on a regular basis and if you do charge to 100% be sure to start driving shortly after it reaches full charge, I read this helps reduce wear on the batteries.

Wow, that’s quite surprising, for a modern EV. I had two Model S cars and experienced about 5% at 30,000 miles. I had assumed Tesla had improved battery chemistry to reduce degradation.

@@UpperWestEV It is Superchargers that destroys a Tesla battery. there is an Uber driver, he is quite good..Cyberlyft or something and he is ina condo and has to use superchargers. His battery didnt last long and got a Reman fitted for $8K.

@@adem-Savs I did quite a lot of super charging on both of my Tesla model S cars, because most of my travel is long distance, road trips.

Do you charge to 100% or 80 and how low do you normally go

@@gandmemoney normally 80%, low about 30%. But…I had a Turo renter let it sit at 100% for several hours and once I messed up and accidentally had it at 100% for some hours while I was sleeping. I have done over 20k miles of road trips and lots of supercharging.

It is a pretty well established practice for NMC batteries and is recommended by the manufacturer (at least in the case of my Kia EV6). The idea is not that you should NEVER exceed 80%, but that for normal driving conditions you should limit charge to reduce degradation. Charging to 100% is recommended about once a month to balance the battery cells, and is acceptable for a longer trip. However there is another 80% rule, and it has to do with minimising charging time. Basically, when on a fast charger, your charging rate will start to slow significantly as the battery gets above 80% or so, and will slow more as you get closer to 100%. Therefore it is often faster in terms of total time to stop fast charging at 80-90% and plan your next charging stop a little earlier. It is both easier on the battery and keeps you in a range that allows you to take advantage of the I5's super-fast charging capability.

When I was home, I would always set the battery charge level to 70 or 80% but while on road trips would set it to 95% sometimes even 100 if I really needed the extra range and even after 40,000 miles I saw very little battery degradation.

Yes, it is! When I’m on my road trips, I usually charge about 4 to 6 DC fast charges a day. My road trips are usually 4000 - 8000 miles at a time.

Definitely good battery chemistry. thanks for sharing this information.

Wow, that’s impressive

Wonderful, it seems like these are really well designed batteries!

That is great! gives one a lot of confidence in the E-gmp battery.

Well, according to Electrify America, I’ve charged almost 190 times in over a year of ownership, that works out to about 14 fast charges a month. My charging always took place on longer road trips where I would do 5 to 7000 miles in a two week period. Sometimes DC fast charging six times a day. kzfaq.info/get/bejne/qtB9iZen2duYYHk.html

@@UpperWestEV WOW! Thanks for the update! Roughly 14x per month would have saved me some serious $ on my elec bill!!

Hello and thank you for reaching out. I will look up your videos. I have loved the ioniq 5, it’s been a great car but I don’t think we will keep it long term. We recently bought a Tesla model 3, in order to be able to use the Supercharger network. Non-tesla charging still has a lot of development to undergo in the United States.

Hello thanks for the question, I wouldn't say I developed a rattle, rather I think it's been there since I bought the car new. There is a rattle or squeak on the front doors, where the plastic interior piece touches the metal window frame. On the driver door it is right behind my ear and when i push on the top of the plastic door panel the noise goes away. Annoying and made worse when playing thumping music. The lack of a rear wiper really has not bothered me so much, I can see just enough. I also tinted the rear window really dark so that reduced visibility, I use my side mirrors more.

​@Upper West EV maybe try silicone lubricant?!

Yes, it was my preference, but didn’t matter when the battery was cold as I could not achieve the higher charging speeds

Hello, you’re quite welcome, I kept the charge level set to 90% for DC fast charging.

try not to use level 1 chargers,,, its like only 70% efficient due to battery care using some of the power,,, use a 240 v , 40 amp charger which is over 90 % efficient

@@MAGApepe Thanks for the comment MAGA, I agree, but us off-gridders sometimes don't have access to sustained high currents. So am happy with 16A@240V (approx 3.6 kW) 😀👍

@@AndyM... well thats sort of a level 1..5 :))

@@MAGApepe LOL, it get's the job done, that's the main thing ! 😆

That’s interesting. What I noticed with the Ioniq 5 over the 44,000 miles I drove it, was that the rated range on a full charge was very susceptible to the efficiency you got in the last few drives. so for example, if you do a long drive up a mountain pass, and then a full charge, You might notice a significant range drop. Not positive that is what you were experiencing but it’s a possibility

@UpperWestEV after reaching out to the ionic forums, they said don't trust the onboard system as a measure. The system predicts a range based on usual driving. My wife drives 100 miles a day at mostly 75 mph. A huge relief.

Oh great nothing to worry about then, glad you got an answer. I don’t like how the auto industry and the EPA calculate range. The typical driver does not drive 50% highway and 50% city in one day.

I have the 2022 RWD SE with the 77.4 kW battery pack.

250 that was the highway range I was getting on my SE last year ...this year with less AC and new route to workplace with way more traffic on it I am getting absolutely crazy results. My average is now 3.9 with a lot of routes being even around 4.3 ....this year I am getting over 250 but on a 80% charge....my conclusion is ...this car loves City and loves Traffic ...the more empty the highway ..the less range I get.

250 is pretty good for standard.

Hey, thanks for your question. I always used the default regeneration because I had read an article that stated Hyundai had configured what was the most efficient and set that as default.

Totally, one major auto manufacturer got called out for failing transmissions after 50,000 miles, just after warranty

@@UpperWestEV battery degradation is in a whole class separate to an ice car. The engine or transmission in a ice car may need to be replaced after a few hundred thousand miles, most people don’t do regular changes of oil etc. In the case of battery degradation with an EV range diminishes slightly which isn’t a big deal account is perfectly fine it’s a it’s a case of false equivalency.

Some poorly designed EVs batteries have seen significant range degradation. As with ICE cars the Initial design and build quality has a huge impact on whether or not some thing lasts over time and use.

@@UpperWestEV so you’re not talking just about the Nissan leaf?

there is probably an accelerating degragation but at 34k miles I feel like the car is actually better now. Kinda weird but someone else in this chat confirmed they had the same experience. Last winter was a disaster as the software wasnt up to date for the RWD. As a result it charged very very slow. But so far this year has been amazing in all ways. Crossing my fingers for winter lol.

Usually 80% sometimes 90

Yes, I think so. The car is very efficient at city traffic speeds. The 303 is based on 50% city 50% highway but I wonder if you drove for 100 miles in town would you have enough left in the batteries to do 200 miles on the highway?

The range is accurate BUT the one thing people dont understand w EV is wind and cold. This happens w Gas as well but we just find a station and fill up. With EV you become painfully aware of wind. I've drafted a few Semi trucks over time. At 34k miles now but trips to Seattle from Spokane can be brutal bcs of wind. But I suspect that can happen anywhere in the country. Single biggest factor in white knuckle EV driving for me.

Totally I was really happy with it my result after putting a lot of miles on the car. I owned a 2015 and 2017 model S and both of those cars experienced 5% degradation after 30,000 miles which was quite common for those cars. electrek.co/2015/05/08/tesla-model-s-battery-degradation-shown-to-level-off-at-5-after-30000-miles/ I was expecting the same with My Hyundai, am pleasantly surprised.

If there had been a difference from wind or temperature the consumption rate would have been different. This was not a difference in efficiency but a difference in capacity.

@@UpperWestEV While I don't totally disagree, I don't think you have enough accuracy from the measurement of 3.5 miles/ kwh to make the claim. You would need a car scanner app to get that, as the car does not report enough significant figures. 250 miles at 3.54 kwh per mile would be 70.6214 kwh while at 3.46 miles per kwh it would have been 72.254 kwh. Both of those measurements from the car display would have been shown as 3.5 miles per kwh yet there is a difference 1.633 kwh between the two. That alone at roughly 3.5 miles per kwh could represent 5.7 miles difference. I also though you mentioned something about winter tires, which could also have impacted the first test. I am not saying what you are measuring is wrong, but I don't think it is accurate enough to draw any conclusions. The other factor is how much if energy was used in either test by the car heating or cooling the battery pack of the car itself.

@@howardschoenberger3526 I have done 3 range test videos the middle or 2nd test was with lighter weight 18 inch wheels and all weather snow tires from Nokian. that was what I was referring to. I achieved 3.2 mi./ kWh for that range test.

@@howardschoenberger3526 My main take away from this test is, that if there was battery degradation it should be much more noticeable than 1% difference between near identical efficiencies achieved on these 2 range tests.

Thanks for your question, I have not heard anything about this, that seems really pricey for replacing just the fluid! I had a general service done at 40,000 miles and dealer did not recommend this. I would think the testing would be fine I never had to replace fluid in the 2 Model S cars I had. I drove each to over 70k miles.

@@UpperWestEV I just pulled up the owners manual in section 9-9 it says Low conductivity fluid - Replace every 35k miles or 36 months this is what I'm referencing.

@@bdk323 Interesting, I’m surprised the dealer/service representative did not recommend having this done.

@@UpperWestEV This is my slight hold up. Most people haven't driven their ioniq5 that much and I'm hearing multiple different stories from oh you just need to test it to 8 to 1200 for replacement. I really like the I5 and want to be prepared for this if its truly an item that needs to be addressed.

Definitely a possibility, could the battery be buffer be a percentage and instead of a set kilowatt hour?

Yes, a happy result

Woah. Sitting in the car watching youtube for 25 minutes, no AC on. The dashboard shows good for 57 miles @ 27%. It just dropped 5% while parked, doing nothing for 25 minutes.

Wow this all sounds very unusual, I did not ever experience anything like that! Is this a recent development?

Could the battery be trying to cool itself while experiencing extreme temperatures?

couple things happen with this. First, your situation seems concerning. Second, if you drove the freeway, the Kw per mile will be less and through off the anticipated range. If should correct if there isnt something really wrong. But again, your post suggest a visit to your Hyundai dealer.

@Paulmetatron8 Yes, I took it back to the dealer twice. The first time, they worked on it for a week, saying sonething was wrong with "vcms". I had the same issue again, the day after they returned it to me. So I brought it back to the dealer again. They then worked on it for almost two weeks, which included their campaign (recall) for faulty "ICCU". Things got back to normal after that.

I’m surprised at how well the Hyundai EGMP battery has held up to all the DC fast charging I have done with it in the last 40,000 miles.

These are all Korean companies, correct?

Maybe once every couple of months. Hyundai recommends you charge the car to full once a month. When I’m at home I set the car to charge to 70%, when I’m on road trips I set the car to charge to 90%

Thanks for the request, but I sold my Ioniq 5.

Ha ha I don’t know about that. I recommend don’t buy used BMWs because it seems to me BMW only cares about the first owner.

hahaha actually that probably isnt relatively true. Im sure your gas mileage has dropped 10 to 15%. Funny post nonetheless.

@Paulmetatron8 you know its true. Gas cars dont have range degradation

@@texasblaze1016 the amount of maintenance that goes into a gas car to maintain mileage is very very time consuming, expensive and you need to buy a top of the line car (thus more money) to get that. BUT YES they do degrade. Maybe you know more than this guy w 5.9 million viewers: kzfaq.info/get/bejne/lZ57qa9516jPlmQ.html
