I claim BULLSHIT ! Local taxi companies using EVs ....have discovered that 5 years ! is pretty well max life with daily high mileage taxi use.

last table is logically flawed.. example 100-25% thats ~400km (varies on ev), 75-65% thats about ~50km therefore you cannot compare charging cycle on these catagories becuz you would need to charge 8times more for the 75-65% to get the same mileage, or vice-versa, you will charge less for 100-25% prolonging the need for a charge cycle. therefore 100-25% effectively could last 6-7 years before a 90% degradation.

Thank you so much!!!

I also have a Tesla and drive about 20 miles per day, so it's easy to manage SOC within a range. I set mine at 70% and charge whenever it falls below 50%. I have a Model 3 SR (not +), so its range is software limited to 220 miles (vs. 240 for the SR+) or about 8% off the top. Also, I have the timer set to charge at 2am when the battery and air have cooled down and to minimize the time it sits in the garage at the higher SOC. With all that said, I'm assuming that I'm keeping my actual SOC roughly between 40% and 60%. Using this method, I haven't noticed any change in range after 5 years of ownership (advertised for 220, but my actual range is 208 by dividing SOC miles by the SOC percentage since I never charge to 100%) with the caveats that I don't know how the software limits range as the battery degrades and not charging to 100% doesn't allow for recalibration. After watching your video, I decided to re-set my max SOC to 60%, but still charge whenever it drops below 50% and reset the timer to have the car charged for a departure time of 7am. This means I'll be plugging in everyday instead of every other day. Not a big deal for me.

Fantastic video. I have been following the electric car scene for yours and this is the first detailed analysis of battery management I have seen explained like this. This is great. If you give the Electric Viking a wink I am sure he will publicise this excellent information to a wider audience.

Please do video for LFP battery

Keep chugging that Kool-Aid…. What a clown show you are.

Keep in mind, a major factor is the chemistry of the battery. Lithium Iron Phosphate is far superior for battery life and seems to be being adopted where maximum energy density is not required. A list of models employing LFPO chemistry may be helpful.

Well, I have one question, so instead of charging my car every single day for the 10% from 50% to 60% of the battery capacity or would it be better to charge only once a week for about 60% from 20% to 80%? If you get 4000 cycles, can you charge every day that gives 11 years although if you get 2000 cycles for the 20 to 80% you get 38 years of battery life that’s my dilemma

In short, if allowed, go for the usage range as close to 50% mark as possible and use as little as possible along with slowest charge and discharge rate. Its just ideal, just stay comfortable with that in mind, LFP would last around 4-8 years for people being aware of this fact

On a 10x 52v is the p7 supposed to be at 28 or 30 ?

One thing youre not taking into account is if youre discharging to 25% instead of 45% then youre also charging less frequently....not every day. So yes you can get 8500 cycles with 10% but youre charging almost every day....where with some of those other at 3000 youre probably only plugging in once a week. So unless your charge cycles 7x the 3000 line which would be wround 21000 youre better off with a deeper discharge

Complete discharge at 300....you would go 1-2 weeks between charges which means it would last at minimum 5 years....300 charges 1 charge a week 300/52 is just under 6 years

I go from 30ish to 90ish when i charge, i charge about once a week.

Super helpful! Thanks!

I charge once a week to full charge 100%

just charge it upto 75% or little less and recharge it whenever you get back home. and try not discharge it under 25% .

I remember watching your original video and thinking, "This is misleading." It still is. Start with the assumption that you use 5 percent of battery power per day. The yellow line (65-75) requires you to charge every other day. So the actual days of charging above 90 percent is 17000 (8500 * 2). Of you take the black line (25 - 100) you must charge every 15 days. The days of charging above 90 percent is about 15000 (1000 * 15). The optimal charge range is the pink line (45 - 75). The days of charging above 90 percent is about 30000 (5000 * 6)!! This is the closest range on the chart to the industry recommended range of 50 - 80, which means the recommended range is almost certainly better than the yellow line. The trick that to many commuters miss is that you MUST NOT charge your EV every night. Instead, run it down to about 50 percent, then charge to 75 or 80 percent. More simply, charge your car on Saturday or Sunday, then wait until Friday to charge again (or Thursday if you have plans for the weekend). Your battery will remain health for longer than the motor, suspension, or any other part of the car. Thanks for sharing.

Nice chart! I think you should use miles or km driven as a measure of battery life. 75% - 65% charging: 10% of capacity x 500 km x 8000 cycles = 400.000 km to reach 90% remaining capacity 75% - 45% charging: 30% of capacity x 500 km x 5000 cycles = 750.000 km to reach 90% remaining capacity 75% - 25% charging: 50% of capacity x 500 km x 3000 cycles = 750.000 km to reach 90% remaining capacity 100% - 25% charging: 75% of capacity x 500 km x 1000 cycles = 375.000 km to reach 90% remaining capacity 85% - 25% charging: 50% of capacity x 500 km x 2000 cycles = 500.000 km to reach 90% remaining capacity Clear winner here is 75-45% and 75%-25%, 75%-65% is almost is bad as 100% to 25%

I’m doing a 65%-45% I wonder if I should raise that up 10% I was basing it on a median of 55%

WOW. I've heard some of this info before, but this is the most in-depth explanation. THANK YOU for putting this all together for us!!!

what is the recommended battery charging/discharging daily routine for the LFP battery would be?

The Battery Management system, (BMS) in most, if not all EV's, already looks after this calculation. Thats how the OE manufacturers can offer the warranty as they do. This only charge to 800 % is WRONG.

Thanks! Great tutorial.

Nice video. I discharge less then 10% per day. Maybe 6%. I have been slow charging to 70%. I think I'll move down to 60% max at home.

I just spent the last couple hours responding to people in your optimal charging videos, apparently no one understands the concept of a DST cycle as pertaining to the capacity graphs you were showing. I think they are equating one charging session to one cycle instead of understanding it as a full charge or discharge of the entire battery pack.

People are missing the fact that one cycle is equal to running through the full kWh of your battery, it’s not the number of charge sessions, it’s the number of times you can charge your battery all the way up and deplete it to 0%. Charging from 65% to 75% over ten different charging sessions is the equivalent of 1 cycle on the graph.

Consider your life expectancy if you drive to work, walk home and walk to work in am then drive home and repeat.

Hi from Denmark - I tried to adjust but it seems lige no matter how much i adjust I keep getting 22 grams. I really don't get how that is possible. Any idea?

I'm glad I found stumbled on this video. I have been charging my 2024 Tesla Model 3 long range as recommended to 80% SOC every day for about a month since purchasing it. Furthermore, I travel a little over 50 miles a day in my case, and sometimes a bit more if I have to run errands or something. After watching this, I'm going to be limiting to 70% for daily use, since even on days that I would travel over that 50 miles, I would rarely drop below 65% to 60% SOC (so keeping in line with about a 15% to 20% discharge cycle). I also happen to live in a pretty hot and humid climate, being in the Southern United States, where we see daily average temperatures anywhere from low 80s to high 90s right now. Thank you for the informative video and excellent commentary!

The most simple way to get it: Q: How could I prevent experiencing a 40% drop in the capacity in 15 years? A: it simple. Use 60% from day 1 😅😅

I usually consume 10% per day, I charge every day at 230V 10A (i dont have three phases) to 70%. Every morning I have 70% battery and potential 300km - but I need 10-50km every day :-)

This is the most useful information I ve got about optimum state of charge . Sincere thanks from a fresh Astra E owner

Hi mate… thanks very much for that very enlightening information. I’m very interested in this content, please put up more, I have just subscribed ! In fact I’m just about to purchase an EV that has the LFP batt chemistry and I would love to hear you present a similar set of recommendations for that type of battery. Once again. Thank you so much 🙏

Universy is nice but not enough. Using more % gives less cycle, but calling for less cycle. I think the age old 80%-20% rule covers it. They just made these stuff to pay their bills.

I think the government should make a law that forces new EV buyers to watch this video before buying an E.V Lots of Uber drivers buy Tesla thinking they're saving money on gas. Then, after a year, their battery is not charging anymore. They used supercharger two times a day, every day.

I have an LFP standard range Tesla, I saw a study where a lab did 90-100% cycles and got about 10,000 cycles out of LFP (probably at 20 C). And that happens to be about my daily usage so most days I do a 10% depth of discharge with maybe a few times a month I go down to 70-80%. Interesting that colder is better. Good thing it doesn't get too hot here in NZ Good advice for NMC batteries. But, if you have LFP you may not need to worry as much, just top it up regularly. The rest of the car will probably fall apart first. LFPs have a flatter voltage curve and my understanding is that 100% allows the battery monitoring system to re-calibrate as it is hard to track the percentage on a flatter voltage curve.

Im late to your post but I just bought a long range model Y and the data is solid. I too drive low km which is 20 miles per day or 32km. I think 60% is ideal at slow charge and no supercharge but I like to share another wrinkle I add. Which is a 80% charge 3-4 times a month. And also a 100% charge once to every other month. There’s variables we can’t account for and need to break rules time to time.

Great video

Looking at longevity as a function of charge cycles is kind of misleading. Of course you will get more 10% charge cycles out of a battery than 90% charge cycles The data should only be comparing 10% discharge cycles starting at different socs. Comparing different starting socs with differing discharge amounts is testing two variables at one time

Hi So I bought a 2024 ionic 5 sel. I drive about 4,000 miles a year. Often <25/day. My daughter told me to charge to 80% when it gets down to about 25-35%. How should I be charging? Thx

That is the number of discharges before the battery gets to 70% of capacity, not to a destroyed battery. Isn’t that what it says? Battery Management System will take care of everything.

This is ridiculous and depressing. So we live out in the country where a minimum return drive distance to anywhere is about 60KLM. Maximum distance is 300klm. What you’re saying is that the battery will be stuffed in a year or two. I think I’ll cancel my order with MG.

Best video cleaning introduction ever.thank you so much. 🙌GB.

What happens to the battery if you only drive once a week . Is it degrading just sitting there.?

All of this is irrelavent! Battery charging using fossil fuels is still less efficient than ICE vehicles even with the given lower efficiency of ICE!!! Unbelievable how people get suckered into this nonsense and think it helps the planet!

Thank you. That was exactly what I was doing wrong.

I have a Tesla main love it. But I know my friends and family who don’t have An EV would say forget it I’m gonna skip the gas don’t have to worry about the stuff😅

Fantastic review !! Very well done
