Also remember that the initial loss is higher and degradation actually slows down.

Thanks for the step by step. My 2019 Model 3 long range all wheel drive at 94000 miles showed 85% in the test.

Great video! I have a 2021 and I’m going to do what you suggested 😁

Did the health check last night and finished this morning. It’s a 2022 Model Y delivered in march-22 and it has 41092 miles on it. The battery shows 97%. Better than I thought.

thanks that is the most trustworthy indicator of battery health I have seen, and compares very well to my case. I just bought my first tesla a week ago 2020 model 3 long range with 48000 miles. Assuming your results are similar to mine since the car is similar, I can expect to lose 10 percent at 50K miles which is about where I am, which means I will lose 32 miles from my original 322 mile range, which is 290 miles. It is in my garage now at 85 percent charge and indicating 254 miles of range. The missing 15% is equal to another 38 miles, which predicts 292 miles which is an excellent match predicting my battery degradation is 10%. Its 40 degrees out so I will not get that in real life, but its good to know. Thanks.

Absolutely going to try this...when my Y gets out of the shop. This stationary brightly painted yellow barrier post came out of no where and swiped my car 😂😢

Im gonna leave it and try again when i wake up. I hope leaving it at 10% does'nt damage anything

Seeing your trip Watt/hr go up tells you your battery is screwing up right ? so if you Watt/hr are high thats a bad sign ! whats is your nomral trip watt/hr ?

I'm at 12% BD too, but I'm only at 40K over 2 yrs. I relied on SC my 1st 3 months till I got Level 2 HC.

I mean wouldn’t it make sense for the car to turn all these settings off when you run the test to avoid all this hassle?

What I learned to get the health of battery information out of the tesla Software, do following: look at your range with 100% and decide through 100 multiplicate with the consumption given of your nominal value (car type model year specific) then you get the kwh battery value with degradation. My M3LR Fremont, 21, 82kwh Tesla: shows on 100% (550km / 100km)*13.6Wh/km = 74.8 kwh means 82kwh -74.8= 7.2kwh degradation is in percent 8,7%

The issue with battery degradation with BEV's like Tesla is that, it varies a lot. Just do the same test on an off-rental vehicle, it will not be this good. In essence all NCM chemistry batteries have around 700 cycles, before a 50%? degradation. But in real life, it is much more, if you keep up to charging between 30-70% most of the time, avoid frequent super charging, topup to 90+ SOC only for long trips, avoid discharging to less than 10%, avoid using Sentry mode all the times etc. Also getting close to EPA numbers? need a lot of knowledge on EV energy consumption. So, the best case scenario, is to buy an EV with the biggest battery, while still observing some of the above mentioned charging discipline. Just some 💭

@teslaafters9133

No. 700 cycles? That is like 2 years. I have owned for 6 years, 106k miles and have 90% of my capacity left. There is also recent research that supercharging doesn't eat into degradat much at all.

Well you said you have 326 miles of range and on the screen, we saw at 100% charge you have 288 miles. Which is exactly 88% (288/326) as the full 24h test shows. So it is reliable and less cumbersome to just trust the value.

I am definitely going to try this. I have been concerned that my mileage is too low. My Model 3 2019 long range AWD is getting 370km or 230 miles with 80% charge after only 37,000km or 23,000 miles. Will let you know. I super charged only once

instead of running the test could you just do the math of what your current max milage is vs how much you should have? So in your case 288/326= 88% Seems like a quick and easy way to get a close estimate

@Jenna_

This calculation would be inaccurate to determine real world range, and isn't exactly the purpose of a degradation test. Tesla, unlike other EV manufacturers, continues to opt-out of a voluntary reduction in range, and uses the more efficient of the two EPA calculations they have to choose from to come up with that 326mi range figure. The range that a Tesla displays on the dashboard is just that, the EPA equation with the current state of charge taken into account. You could determine a theoretical maximum based on reported battery health, but none of these calculations take into account a persons driving style and/or the environment in which the vehicle is driving around in. Remember, the EPA driving cycle is 55% city, 45% highway, that highway portion is completed at 48mph, and EVs excel in low-speed environments. The degradation test is more to show how the battery has worn given the conditions its been driven in, and gives the current owner and/or prospective buyer an idea of how long that pack will last until its in need of service or replacement. In most modern EVs, degradation tends to slow as time goes on, because the pack allots a more of its nominal (total) capacity for critical vehicle systems and degradation, to minimize the impact it would otherwise have on range. Tesla chose to apportion more of their battery pack to useable capacity for increased range, at the expense of more noticeable degradation as the pack ages.

My question is why do you believe the Tesla health test? If the health test shows less than 70% health then the warranty is triggered. So tesla has an incentive to make its health test more optimistic.

That seems like a strange way to test battery capacity. The way I’ve been taught is by charging the batteries to 100% then putting it on a load until the batteries discharge to a certain level. The load and level is published by the manufacturer. When done on a string (multiple battery cells in series) of batteries we measure each cell and the overall voltage. On a Tesla or any other EV, there is no way they are going to measure every battery cell, there are just too many. For example, I’ll be testing a 24V string consisting of 12 batteries each providing 2V . We’ll say the manufacturer tolerance is that the batteries will be at or above 1.75V per cell by the end of the test. This calculates to 21V for the string. Let’s say the manufacturer rates it at 50 amps for 10 hours. If we put a 50 amp load of the string, each cell should read at or above 1.75V and the string at or above 21V. Once the string falls before 21V you stop testing and record the time. If it lasted 9 hours the battery system capacity is 90%. Not sure how the Tesla can truly calculate battery capacity when it starts below 50% charge. Battery voltage is not linear as it discharges. Also, the rate of discharge varies. In the example I gave, a battery lasting 10 hours at 50 amps will not last 5 hours at 100 amps. It will be closer to 4.5 hours. The inverse is true as well, if only providing 25 amps, it will last closer to 24 hours. My guess is that they tested a bunch of batteries, averaged them out, then plug in those battery voltages to represent your batteries. That’s probably the best way to test the battery capacity without knowing exactly how your batteries operate, but that is still not a true test or your batteries.

There are also many ways an EV battery warranty is voided. Water ingress, cooling system and physical damage warranty might not apply. Also when warranty does apply with Tesla you get a re-manufactured battery with similar degradation. The resale value will not be good as these cars age. I think if I owned one I'd be selling and upgrading when the battery still has a couple years of warranty left on it to maximize my financial losses.

While it's not a good indicator of how far you can drive, because you're not going to drive the same as the EPA test, it is a fairly accurate way to gauge degradation. The battery health test is unnecessary.

I would do a real world test, charge to 100%, drive to 0%, then change display to metric, multiply the watt per km by the number of kilometers and that should give you a better state of health both in range and actual kwh capacity remaining.

At my 2002 Ford Focus ZX3 miles, that would have 1/2 a battery left, probably a lot less due to age. That car that "saved the planet" would be in a landfill at least a decade before mine, so no, they don't save the planet. IF the battery is recycled, very little is recovered and makes tons of CO2 in energy use to do so. Yes, I researched it. Lithium also uses 1000 gallons of precious water to make enough for a BEV battery. The break even on CO2 with similar-sized ICE car is YEARS down the road. There is no free lunch.

@andrewjoy7044

6 ай бұрын

I think you need to do your research again. Batteries are fully recyclable. The biggest problem for firms recycling batteries is they don't have enough batteries as EV batteries in general are lasting much longer than predicted. Lithium does use 1000 gallons of water to produce an EV battery. Once produced they don't use any water. Did you know that in the USA, 3 to 6 gallons of water are needed to produce one gallon of gas. An average American uses 656 gallons of gas per year so that is 1312 to 2624 gallons of water every year. After 10 years that is 13120 to 26240 gallons of water. So as for water usage which is better. Oh, one more thing, a lot of the water used in oil production becomes contaminated. The life span of modern electric cars is unknow to a large extent because they have not been around long enough. There are still Nissan Leafs from 2010 driving around on their original battery packs (Not far I admit). Same with the original Model S' from 2012 after the original battery packs were all replaced due to a fault in the original ones. There are many who believe that modern EVs could last as long as 1 000 000 miles, but since this is 50 years of drivinh for the average American motorist we will have a long wait to find out.
