What is the Electric Vehicle 80% Rule? | EV Basics
In this video we tackle the “80 Percent Rule.” What is it? Well, most of the time you should only charge an EV to 80%. Why is that though? We’ll explain how reducing your charge can maintain the overall health of your battery and be a much more efficient strategy for tackling road trips in an electric car.

I leased my EV car for 3 years…😂 I really dont care about the battery..😂😂
Uber driver here. I charge from 30% to 80% using Level 3, 3 days a week and then charge up to 90-95% overnight using Level 1 charger at home. Charge level 1 usually over the weekend. Should be fine with degredation since it’s a Level 1. 50k miles, 2022 Chevy Bolt EUV.
My 2021 MiniCooper SE makes only 28 of the 32kWh battery capacity available. I wonder if this is another way to force an 80% max charge (87 actually) so you don’t have to think about it.
If you own an electric car you are already letting Joe Biden do your thinking for you. So have the battery removed park it in your garage next to your treadmill and get a bicycle.
100% gas refill since brand new, nothing changed. EV? No thank you.
If you want to extend life of Nickel based batteries keep regular charge limits to 70-75% and recharge at 40-45%. This usually is more than enough for most daily driving needs . This is especially important in hot weather . This doesn’t apply to LFP batteries .
just switched one of my cars to a model s long range and found out the range is only about one third in winter.
Shouldn’t they advertise the reduced charge as the ACTUAL RANGE? Reducing my Kona from 64kwh – 300miles to 51.2 – 240 miles? No. Way.
The long range Ioniq 5 has a 77kWh battery so adding 70% (going from 10% to 80%) is 54kWh. That takes 18 minutes? That’s way too long. As someone who can’t charge at home that’s why I don’t have an EV.
I understand that any rechargeable battery should mostly be charged to 80% but sometimes on long highway trips I would go to 100% now and then
Or they can limit the capacity to 80% and display 100% to the user.
Hey people, can I ask a very important question here? I’m anxious to get really good informed opinion on this because unfortunately living in Southwest, (specifically Las Vegas) we are more vulnerable to our EV’s being permanately damaged right? Well that’s my question, does level 2 charging and driving my EV (even if it’s liquid cooled with proper thermal management) irrevocably compromise the long term battery range of the battery when the car is charging at night and it’s still 85 degrees? I know I should expect less range in the summer, but does driving the car in 100 plus temperatures from May until late August, actually permanately shorten the battery’s lifespan , or is driving the car in these temperatures and charging the car during these warm to severe hot summer months, going to have only a ”summer impact” and when the temperatures cool in the non summer months, I won’t see any permanent loss of range over time?
I wish there was consistent opinions out there, when I ask this question, but there isn’t,
85% is the sweet number for me. 👍🏽
Okay Seth Myers. lol
I am a self defense instructor and was using an Ev Charging station for the first time, please note your surroundings- the charging station I was using was in a sketch part of town, and I was using it during the daytime… I truly believe this man that approached me was going to try and rob me until I acknowledged him, he then turned around, and went a different way. I was trying to figure out my app for the first time and was spending more time than normal trying to troubleshoot the app and charge station (I’m a tech guy imagine that). Please everybody be safe out there know your surroundings and walk the perimeter of your vehicle while syncing up to charge… be safe out there God Bless
🚨We have an updated version of this video that talks about LFP and what automakers are recommending now that there are more EVs on the road! https://youtu.be/nTOMpxycEss
Mines on a 2 year lease and will be 100% charge from day one.
My Honda e struggles to do 80 miles in winter from 100% !
👎 i have paid to NOT have advertisements on YouTube, you put it in the video gives thumbs down 👎
If you aren’t concerned about the time it takes because it is normally when you are asleep, does the 80% rule still matter? I have been driving Leafs for years. Done all of my charging at home. And never limited my charging to 80%, I never noted any degradation of the batteries at least not until just recently. I had a problem that seems to have cost me 12 miles of range.
Slow charging any battery is always best for it. The slower you charge, the more even the charge gets to the cells. The longer range you should have, due to a more deep charge. Fast charging surface charges the cells, so they aren’t technically receiving full charge capabilities.
Want the battery to last longer….slow down. Big difference n how often you have to charge.
Of course, WHO IS CHARGING FROM 0? Or even 10%? I live in L.A. We NEVER let any vehicle go below 50% of charge or tank. Never know when we need to flee a fire or whatever. In fact, due to …. stuff, I haven’t been able to get a full charge in a month. Been puttering around town around 100-140 miles. Eco mode is working. But I hate it.
Why are they recommending charging all the way to 100% on plug in hybrids?
some cars are better than other at this… Hyundai Iconiq fro example is rated at 38kw… in actual fact the battery is around 40-41, just by default your not allowed to access as a consumer that part of the battery to keep the health up
lol so in winter let’s fill the battery up to 80% and lose 20% because I want to be warm, Let’s hope I don’t have a long drive or I won’t have the range to leave the house, your battery in your car is no different to you mobile, starts off fast and slows down when full, only difference with EVs people won’t want the slowing down part.
Charging stations in general are a waste of time. Either charge on your home or stick to gas.
I’ve got a MG5ev with 94k on it. I bought it new in 2021, And it’s been charged at home to 100% every night. I’ve just lost about 20 miles of range since new. It’s used as a private hire taxi, so I need it charged fully for the next days work. I’m happy with that.
It’s 2025 now, a few years ago China has a car called BYD they have a LFP easily to charge to 100%
Now it’s even better and full fast charge to 100% is even better.
I am doing 40% —> 70% now for routine driving and charging. I reckon I won’t need to top it up from the home-charger much more often than twice per week, and only save the 100% for long country road trips 👌😃
If you limit your changes capacity then you are essentially reducing your range for each charge
I charge my phone not my car
Don’t let the charge fall below 20%. Don’t charge over 80%. The real range of an EV is 60% of that advertised by the manufacturer.
85% is the sweet number for me. 👍🏽
Hi Is the 80% rule alos relevant for Tesla powerwall batteries, inparticular limiting teh charge to 80% to preserve battery life? Thanks
I have 2 Chevrolet bolts that we routinely charge to a 100% every night and deplete to 5 to 10% every day. They both have well over 200000 miles with no battery degradation. I think the 80% thing is something that someone made up somewhere. Just to make a video
Wireless charging 🤯
EVs are so ridiculous. The 80% rule is actually the 60% rule Don’t forget you’re not supposed to discharge your vehicle below 20%.
80% slow down is mainly because of software, trying to keep the battery life / condition.
Question … when charging from 80% – 90% does the wall charger use more electricity than when charging from 70%-80% since it is connected much longer or does it just use less electricity over a longer period of time?
One year later… It doesn’t really apply anymore to the new LFP blade batteries. You charge them to 100% with no damage. And if you had only known back then about sodium ion batteries…
That’s the Problem with EVs 10% to 80% is only 70% of the Adverstised range 🤷🤦
I m paying 100% for a Car I want 100% of the Range it has, I mean is not like it has 500 miles range, 70% of only 200 miles range is 60 miles lost 🤦 and only a 80 Miles Return trip
100% charge every time, after 36000 miles in 2years no degradation and couldn’t give a toss anyway. Will get a new car in 2years. Lease companies problem if there is one.
Lol, 18 min, from 10-80, good luck finding a charger to do that. Good luck finding a charger that works or not occupied
This means you pay 100% of the price for 80% of the EV performance. It’s borderline scam
theater is the best example lol
According to the US Dept of Transportation, most drivers drive 39 miles per day.
Oh my God YouTube needs to implement some sort of standards
I’m so sick and tired of clicking on something and then having it be so goddamn disappointing
I’m a happy non EV buyer and don’t have to think about pumping gas to full. I can floor it and get full power. With over 100,000 miles on the odo. I’m totally reassured that the distance I travel is the same rain or shine even at -20.
at 3:50 – your EV is slow charge so it takes 90min top top up. Tesla Mod3, ModY even LFP does not do that. It only take 45min from 20 to top up 98%. charging to 100% is all depend on your EV brand and your need. If I got one L2 at home then I can charge at any level of my convenience. If I only charge with L2 at work, slow charge, I will do 100% any time I can because no L2 at home. EV is not for many driver choice.
