What I'm currently doing is charging to 80% on an AC charging post in the street (11kw). Then I drive my car down to 30% and charge again. Four or five days between every charge. Hope this is an OK way of doing it.
In your situation, where you have to rely on DC fast charging, you can minimize battery degradation by limiting your finishing charge to 75~80%, rather than "juicing" up to 90% each time. you can also help offset the difference by driving for maximum mileage per kWh. (electric equivalent of "hyper-mile" driving) That will help reduce the peak amounts of current drawn during acceleration, as well as the current returned to the battery during regenerative braking. The only disadvantage of fast charging, is the cost per kWh, making it as expensive to drive as a good gasoline Hybrid car.
Dude, you *cannot* charge your car to 100% and you *cannot* over-discharge your battery. What you see on the state of charge (SOC) indicator is *not* the full range of the battery voltage. What you are seeing is *the range of the battery voltage that the manufacturer allows you to use* . When you see your charge indicator showing low, you are seeing that the low voltage limit determined be the manufacterer is being reached and the mfr. will simply shut the car of, but there is still charge in the battery. Manufactures are not stupid. They have to ensure that these battery packs last 8 years or 100,000 miles and their battery management software and their battery charge controllers are there to make sure this happens and one of the keys do doing that is to never allow the battery to charge to its actual full capacity and never allow it to drain below it's lowest safe voltage. This isn't a freaking flashlight battery. It is a massively complex system that makes it really hard for you to screw up your battery.
This video only has 460 views at the time I’m leaving this comment, in 5years when ev’s becomes more poplar and adapted by society this video will have a lot more views.
You've been training all your life with your phone batteries. Just treat it the same. Its EXACTLY the same. Only use between 90% - 15%, keep it charged at all times, but below 90-85% and over 15%. Done.
they don't last the life of the car! then you are in for a 15k-25k repair bill. Optimal battery life is achieved by keeping battery 20-80% charge. This also means that actual advertised range is cut by 40%
If you only used your EV for leisure purposes, ie not everyday use, would level one charging be the most efficient ? I seem to get more mileage from this method then level 2 or 3 ? When using the KIA mains adaptor, which can run at 6, 8 or 10 amps, when charging at a slow 6amps I’ve had a full charge 347 mile on a NIro which is supposed to have 285 miles full charge ?
So it sounds like I should use the departure feature instead of charging as soon as I get home? SR+ here, I usually have 80-100 miles when I get home from work then charge to 212-218 miles (Tesla's wall connector)
Unless you are going to let your car door for an extended period (multiple days) then I would just daily charge to 80-90%. If you really want to play it safe you can use "scheduled departure" but I don't think it's completely necessary.
How much degradation is currently on your battery pack? Nice Video! This was Tesla Response to my 2020 M3 LR, because I'm down to under 300 miles after only 3700 miles: "HV battery has degraded by about 3.9%, normal battery degradation based on fleet average" Verified Proper Operation. Referred customer to range support page. Correction: Remote - Education
I'm at about 300 miles right now, but I've heard the biggest "drop" happens quickly then it plateaus after that. If the trend continues at that rate then it is probably a bigger issue
I have heard contradictory information on whether to charge till 80% or 50% or 100%. Car manufacturers say its best to slow charge till 100% so that all battery cells in battery pack are calibrated and DC till 80% cause after 80% battery charging is very slow which matters while DC fast charging.
Keeping the charge near the middle is best but it's also good to occasionally do a 100% and then down to as low as you feel comfortable with to calibrate like you stated
Good advice, regardless of display showing usable battery, not actual battery. Software/hardware doesn't do everything to protect your battery. Manufacturer recommendations are worthless once your warranty runs out. I have limited options with my 2015fiat 500e "80' mile range. I try not to go 100% unnecessarily & stay above 20%. I recently saw sudden drop in range approx 10%, most noticeable under high drain, my drive home from work, 25 miles at 72 mph. I've gone back to doing some L1 charging at home. Battery degradation is not the only concern, sell leveling, there are limits to what BMS can do.
you mentioned to use level 2 as best option...is it not level 1 that offers the best longevity for EV batteries? Not very realistic because of slow charge. my understanding a slow charge is best always.
Extended studies now have shown DC fast charging itself isn’t really a major factor in decreased battery life. The temperature of the battery plays a much bigger role in this. Just keep an eye on that temp meter when charging.
i dont agree with not full 100% charge.. i have a leaf dec 2013 with still 10 bars of health i charge only at home every day to 100%! 240 volt 2,2kwh.when im home there is 20% left. i own it for 4 years now and bought it with 69.000km on it. now its 150.000 km with still 10 bars! im from the netherlands and my batterypack never go over 6 bars for the heat.
Example. I drive my Tesla dual motor 25 miles per day or 175 miles per week. Do I charge everyday to replace the 25 miles in a short charge and bring the charge up to 80% or do I charge once per week and replace the 175 miles in one longer charge up to 80%? 7 short charges or 1 longish one? What is better for the long term battery health? Some say it's best to ABC Always Be Charging or always be plugged in. Elon says a plugged in Tesla is a happy Tesla. What is better for the battery?
Likely a negligible difference between the two, especially for home charging. I generally recommend logging in every day so you wake up with 80%. It's the best part of driving an EV
Hey I’m getting my Model 3 Performance in a few months and also don’t have a garage unfortunately, however, there are many level 2 EV chargers near me, including the official Tesla Superchargers (only 5 minutes away from me) so that’s nice, though having a garage would be incredible when owning a car like this 🥲
You claim that the “best” thing for your battery is Level 2 charging - when in fact, if the rest of your spiel can be believed, it would be Level 1 charging. Advice like you’ve provided for charging to 90%, 10% and 50% may technically be “better” - but without being able to quantify “how much better”, one could make an argument that all of this micro management provides a poor return on investment for the extra attention and effort. I’d also argue that if this truly were the best advice for managing your vehicle battery - and if it resulted in a significant longevity increase - then the car would manage this automatically and it would display 100% and stop charging when it truly hit the 90% capacity mark. I’d like to see a longevity comparison between identical usage patterns - but someone who always recharges to 100% as quickly as possible vs someone who follows all of these best practices showing: - the battery degradation curve over a decade, - battery health after 3 years, 5 years, 8 years and 10 years If following all of these “tips” are going to make my battery last 1 month longer than someone who doesn’t follow them - it’s absolutely not worth the effort and attention - but if it’s going to last an extra 2 years, it probably is. Until someone publishes actual data showing the real word difference, I’m going to assume the difference is “negligible” and do what is most convenient for me. Claiming that something is “better” for a battery, doesn’t necessarily mean that people should do it. Prove that it makes a *significant* difference to longevity and then I’ll consider it.
Search Battery University article 808. Figure 6 sums the longevity comparisons nicely. But you raise a good point about real-world ability/expectations to manage battery use as close to 50% as possible. It is particularly difficult for those with PHEVs with a smaller battery size to begin with.
lol all EV's made before like 2017 literally had laptop batteries inside them. theyre the same thing. liFepo4 are the only newer batteries which kind of suck in terms of weight vs range. teslas are super heavy cars most cars are about 1 ton or 2000lbs model 3 is about 2 tons or 4000lbs model x is almost 3 tons or ~5500lbs, and ironically qualifies as heavy machinery which you can write off business profits here in the US, kind of like if you bought a big truck for ur business due to depreciation tax incentive.
One of my business associates has a 2 year old Tesla Model 3. New it was good for 300 miles. 2 years later its struggling to get 250 miles. It also looks like a blind 3 year old put it together. Nothing quite fits right or lines up. If an EV was fit for purpose. The worlds governments wouldn't need legislation to force us into buying them. Lets face it. Looking back into history, every new thing has been better than what it is supposed to replace. The EV is a major step backwards.

Recently findings are that use of fast chargers aren't as bad as initially thought

The best, makes sense to leave more buffer on the bottom.
In your situation, where you have to rely on DC fast charging, you can minimize battery degradation by limiting your finishing charge to 75~80%, rather than "juicing" up to 90% each time. you can also help offset the difference by driving for maximum mileage per kWh.

Everything in this video is just CORRECT ✅
Nice job explaining the best ways to limit degradation!
Thanks!

I recommend updating it to talk about various apps, how different makes control charging, etc. But this is a good basic video.

Great video!! just wanna let you know that you are defiantly too close to the camera.
Thanks! I can definitely adjust for the next video.
Heroically, bravely close to the cam
Thank you
Mercedes recommends to charge up to 80%… Should I follow that or turn the limit down to 70% or less ?
100% spot on good information bro keep up the good work

What tips did I miss here???
Don't charge the full, don't drain it all the way
Extended studies now have shown DC fast charging itself isn’t really a major factor in decreased battery life. The temperature of the battery plays a much bigger role in this. Just keep an eye on that temp meter when charging.
What temp meter?

That's odd, l don't have any of those issues with petrol..🤔🤔🤔
Oh there's plenty of issues with petrol 😂

First :). Can’t wait to join the gang.
Be ready for the hazing
@ AlexSibila Im just want to let you know I used your referral code . Thanks 😊
Thanks so much!

PROBLEM OF A CAR LITHIUM BATTERY WILL KICK YOUR BEHIND..RIDICULOUSLY HIGH
Nice opinion but no science support provided
So, a happy Li-ion battery is a half charged battery.
Ideally, 20-90% is best.
Stuff that.
I like a full tank of fluid.
$50,000 to replace battery. No thanks.
@Radioman. I was being sarcastic… gas vehicles are more reliable, especially in cold weather.

Just don't use your EV. Put it in a display window and make sure it is fireproof . And your battery will be OK
That's my plan. Just finishing up garage renovations to put in a lot of windows
Based on my research there is no saving money. Save now for EV and pay now for gas vehicles
lol all EV's made before like 2017 literally had laptop batteries inside them. theyre the same thing. liFepo4 are the only newer batteries which kind of suck in terms of weight vs range.
teslas are super heavy cars
most cars are about 1 ton or 2000lbs
model 3 is about 2 tons or 4000lbs
model x is almost 3 tons or ~5500lbs, and ironically qualifies as heavy machinery which you can write off business profits here in the US, kind of like if you bought a big truck for ur business due to depreciation tax incentive.
