    I had a 2013 Nissan Leaf that I charged overnight to 100% everyday because I needed the range for my wife’s commute. Now the Leafs were notorious for battery degradation. BUT, I had 80% capacity when I sold the Leaf with 80K after 6 years of use. I also frequently charged using the CHADEMO fast charging port when I used the Leaf for Uber driving. This is REAL WORLD experience not theoretical musings. However, I do agree that charging to 100% wastes time.

      It's good to hear that even the Nissan Leaf, with its air-cooled battery can hold up well for all those years of hard use. Newer EV designs with properly cooled batteries should fare even better. Thanks for watching and commenting!

      My first EV was also that 2013 leaf, charged to 100$ twice every day (with type 2 charging, 3,7KW) due to my dayly distance. To much for one charge. At my work I was able to charge. At home also on my private parking (using the 2KW charger deliverd with the leaf). Sold it after 8 years with comparable amount of km , gthe car still going strong. This due to not needing a second car any longer because retrirement from work. And only keeping the long distance car, at that moment (2021) a brandnew ioniq 5.

      I saw a study done (I'm sorry I don't have a link handy) that illustrated that there was an effect on battery life, but it was single digit degradation over several years. In short, I don't think regularly charging to 90-95% is anything to worry about. I do try to my (air-cooled) batteries well short of 100% on the hottest days, however. I've never had an overheating problem, just going by what I've read on the net...

    Thank you for the video. I wonder how many people buying an EV car are told this when they buy it. BUT and it's a BIG BUT, if you are only supposed to charge your EV battery to 80% AND you are ONLY supposed to let the battery get to 20% before charging that means you are ONLY running on a 60% charge! So, if an advertised range of an EV is 300 miles, in reality it is only 180 miles!

      Not sure milage matters, but how many cycles in charging does. The 80% rule is a good standard, drive to about 30% and recharge then to 80%. I think less times "Hitting the battery" makes sense. I'm not yet sold on the idea of the current EV market. Yes, a 100K battery warranty is like a 100K gas engine warranty but the EV car value depreciates almost 2x faster than a dinosaur squeezing engine car and most combustion engine cars can last easily 300K now days.

    @JasonTaylor-po5xc Рік тому +36

    The 80% rule is mostly to help with battery longevity but mainly for batteries with significant amounts of nickel in them (NCA and MNC). However, a somewhat newer chemistry (LFP) uses iron instead of nickel. This does three things - lowers the overall energy density, significantly lowers the fire hazard and removes the 80% rule for battery health. Because of the lower energy density, the same size battery will have a shorter range but you get that back by being able to charge to 100% on a daily basis.
    As pointed out, the closer to 100% you get, regardless of the chemistry, the slower the charging becomes to the point that last 20% takes longer than the first 80%. For my car, I charge to 90% on a daily basis (home charging).

    Another great analogy which I learned in high school physics class was filling up a glass or bottle of with water at the tap. The closer you get to the bottom, the slower you have to add the water otherwise the air bubbles trapped in the water will pile up and push water out.
    The increasing voltage in the battery creates a similar sort of "resistance" to charging which is also why KIA moved to 800 Volt charging technology.

      The batteries in an EV do not work the same as batteries in cell phones, laptops and tablets. Don't fool yourself that because they all have Lithium (which is a small percentage of the materials used) that they function the same. EVs use multi-module, multi-cell packs with cooling systems and sophisticated battery management software. They can stand 100% charging and discharging.

    A lithium ion battery is happiest at 50% when there is perfect equilibrium of ion charges between the positive and negative terminals and the least likelihood of electroplating which will permanently remove ions from circulation and thus degrade the battery. This is a chemical reaction and is a function of both heat and time. Up to 60% charge there is virtually no time based degradation. Up to 80% the amount of degradation is fairly minimal and that has been adopted by most batteries as a good compromise between function and degradation. Having said that 70% is better then 80% and 60% is better still. If you don’t need the full range as I don’t then it’s best to keep your charging in 40-60% band

    The important time spent charging is 10 seconds which is how long it takes me every couple of days, compared to a 10 minute drive to the gas station every week. 51 weeks = 510 minutes filling up per year or 8.5 hours water. When I take a couple of weeks for road trips and have to recharge, I always spend more time in restroom and in line to buy a snack than charging.

    Also the level number of charging matters. Level 3 heats the battery the most and heat degrades the battery. High amp level 2 compared to lower amp level 2 degrades the battery faster too, but not as bad as level 3. Level 1, very slow, prolongs the battery the most. I charge 12 amp level 1 since retired and in no hurry.

      But I'm sure this is valid for cars with a less optimal battery management. As you correctly state...the temperature is very important for damaging the battery. Modern cars will cool down the battery when charging at level 3 (also when needed at level 2 , 11KW or 22 kw). This prevents that damge process due to heat.
      Older cars (Nissan leaf) did not cool the battery good but reduced the level 3 charging speed when the battery got warmer.

DCFCing past 80% slows the process down, so we probably wouldn't do that too often (unless we needed to), but look at the rule more as guidance than anything.

    better yet, learn the charging curve of your vehicle. some might start dropping speed at 50%, 60%... so if you can, its faster to charge more often. where i am from, a 300 mile EV shouldn't really struggle reaching the next charger. as for battery longevity, its ok to charge beyond 80% as long as you intend to use it and not just let the car sit at a high SoC for days. looking at you, company fleet managers. it might also reduce regenerative breaking which is a neat feature.

    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.

But Ive heard the new cheap LPF batteries can be fully charged all the time so check which battery you have. This only applies to a 3 at this time I think but it will expand. Range anxiety is for real though. The big failure of the EV;s is when you go 80 or above. Range drops like a rock. 70 is OK though but it hurts watching cars zip by you.

    One of the things that electric vehicles range is it you really shouldn't be using above 80% or below 10%. Drop the range estimate significantly. For example your 250 mi range really isn't 250 it's 200 if you go to the 80% number unless if you also drop below the 10% number. That would be on a flat road, not carrying a load combo, a decent ambient temperature, and driving at an optimum speed. I'm not sure how that would change with regenerative breaking on non-flat surfaces.

    So here's my info. I'm an electronics tech and I've been an EV driver around the last 20 years or so. My current vehicle is my 4th ev. It's a 2012 nissan leaf with over 80,000 miles on it. Purchased it used from the dealer with 5,000 miles on it. It was a demo model, showed hard use, tires and brakes almost shot even with only 5k miles. I do an 80% charge spring through fall, 100% charge in winter due to nissan PPD. My current battery capacity is about 8 of 12 bars according to the leafs guesstimater. Puts the vehicle somewhere around 60% of original battery life. I'll probably get another 2-4 years out before my range to work requirements make a battery swap is unavoidable. Although I may just drop the battery compartment and do a conversion to LiFePO4 batteries, lower initial capacity but more stable an longer overall life. Also DIY battery gives me the opportunity to add thermal battery management.

      The concept I'm working on is one I initially considered for server cooling. Immersing the entire system in a liquid. The issue is finding a liquid that fits all the needed characteristics. It must be non-toxic, cheap enough, available enough, insulating, non-flammable, and remain liquid within the required range of temperatures. Immersing the cells would not only allow for rapid temperature adjustments but could also serve as a ready made way or reducing the risk of lithium battery fires. This by not only temperature regulation but by isolating the cells from air/water. So far this is just in the idea stage, really haven't delved much into it, but the concept seems promising.

    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?

    • @EVPulse

      Batteries are consumables, so over time they'll ultimately lose some capacity. But also don't overthink it. If you're plugged in and have active thermal management (like nearly all EVs), the car will maintain the battery in its sweet spot especially when its plugged in pulling power from the grid.
      You might see less range in the summer just because you're using energy to cool the cabin. Plus if the battery has to be more actively cooled that takes energy. But I wouldn't worry a ton, these are tested in extreme heat and cold. Just leave the car plugged in when you're parked, pre-cool the cabin before you unplug, and just go live life :)

    A battery has internal resistance. The “effective” charge resistance is lower in value when the battery is lower in voltage compared to the charger source voltage. The battery charger has a source current limit along with regulated voltage.
    When the charger is connected to the battery and the battery is low in power the battery will demand more current to be charged. This is because the battery has a lower “effective” resistance value. As the battery becomes charged the difference between the battery voltage and the charge voltage becomes smaller. This in turn lowers the current being demanded from the charger. The charge rate will slow down. The charge rate speed is not linear. It follows an exponential logarithmic rate. The log rate is 2.71828.
    Along with this in side of the vehicle is a charging manager circuit. This circuit uses a micro controller along with software to manage it. It senses current, voltage, and temperature. The battery manager circuit is designed to slow down the charge rate if the battery becomes too warm. It also slows down the charge rate if the battery appears to be approaching full charge. This is to help keep the battery system cooler.
    If you were to have a current meter installed in to the charging system you would see when the battery is near to depleted the charge current will be high. As the battery charge level goes up the current will drop. If you were to log the rate of drop over time you would see the rate of charge vs time would be declining more rapidly as full charge is approached.
    The demand of only charging to 80% is really to keep the temperature of the electrodes lower and to prevent over saturating of the battery chemistry. Using an 80% charge is more of a theoretical process than actual. When limiting the range or depth of charge cycles this will increase battery life. If you run a battery down to empty and fully charge it back up, over time the number of acceptable charge cycles will be reduced. The number of rated charge cycles on a battery from most manufactures is rated from 20% to 100%. If you are charging at 60% for example, you would probably have about double the available amount of charge cycles.
    Even though your phone uses a Lithium-ION battery, it is not the same technology as the battery used in an EV. They are based on a different type of design even though they are both using Lithium-ION chemistry in their technology.

    Good video, but it seems the 80% rule is slowly falling to the wayside in favor of 90%. Even the Polestar 2 that you have in the video, now recommends 90% and fast charges reasonably quick to 90% after more recent software updates. Though it still ramps down steadily above 60%, but over 90% is now the REAL drop off in speed.
    The concern over battery health/longevity seems to have been overly conservative early on, and now that there are more and more EVs out there, it seems the difference between 80% and 90% is negligible. Probably more important is the number of charge cycles done with DC fast charging vs. AC trickle charging, rather than whether the stopping point is 80 or 90%.

Now, that is still substantially slower than the first 70%, but still pretty good.
    As for the 80% rule, Hyundai does recommend charging to 100% AT LEAST once a month in the manual.

    There are EV owners who have only ever Rapid charged to 100% and suffered no notable ill effect. The conditions affecting battery degradation are more nuanced than just keeping your battery to 80%. The only REAL benefit of charging to 80% is time saving. If you don't absolutely need that extra 20% (and these days most people really don't) then you never need to charge above 80% when the rate slows right down. Most modern EVs can go at least 120 miles on an 80% charge. You're better off plugging into a 3kw or 7kw charger and going away and doing something else for an hour if you really want to fill in that last 20%.

    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.

    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

    True for normal battery packs but the newer LFP batteries can charge up to 100% daily!

      Yup, and when we talk about it in future videos / series we will mention the LFP difference. Especially now more OEMs are using it.

    Wow, I am still an ICE owner but, lets see. So, I get an EV with like 240 miles (tesla model Y for example), So, 80% of charge, that is around 190 miles, and now it's winter and is -5 degrees out. So, not want, NEED heat. Take away -41% and that brings it down to around 114 miles of range.
    Now, EV range is based on how you drive, if you on the highway locked at 65mph, you might get close to 114 but, if you deal with "the moron factor" people not knowing how to drive, passing morons etc. You will get like 75-80 miles out of that EV in the winter depending on how aggressive you drive. Most EV drivers I see on the highway are locked at 65 and will cause traffic problems in the morning.
    With a lot reading I have done about EV range, it's not exactly like ICE cars, you go 80 instead of 65, you pay big time. ICE cars, normally you know where you stand, I have 400 miles on a fill up on my daily driver, I know if drive aggressively, that will be around 375-390 miles I get out of it. The numbers are there and tested.
    So based on what my daily gets in range, around 400 miles, for an EV to get same range, in WINTER and summer, with the 80% figure, it would need to be around 750 miles of range to factor in all that (so I can have A/C in the summer, and heat in the winter). By the Way, the biggest one, I think the Lucid Air, is around 550 miles.
    EVs are not fully ready to replace an ICE car in my eyes. Not going to pay MORE for less (ICE car vs. EV and milage in all cases I stated). They have a long way to go....

    Not even mentioning that it costs more charging to 100 percent because you can't recuperate when on or near 100 percent.

  • @Kvickification
    @Kvickification Рік тому +1

    If the minimum is 10% and 80% the highest, you leave out 30% capacity and the real world consumption does not match estimated range supplied by manufacturers, even worse in winter 😂

  • @joebloggs6131

    i thought the rule was 85% for lithium batteries, in general, to reduce an extreme amount dendrite build up within the battery. must be different for EV's with a high torque, high draw demand, electric engine.

    I've been driving ICE cars for the best part of 40 years, and I have never had to worry about filling the tank up to 100% full or running it down to virtually empty.... I've done this thousands of times, and I can't ever remember the engine or fuel tank blowing up 🤣 or my range decreasing 😂 And the first litre goes in the same speed as a last litre (and every litre in between) 🤣🤣🤣

    • @EVPulse
      @EVPulse  Рік тому +1

      Running to virtually empty every time isn't great for the fuel pump, which is cooled by the fuel in the tank. And car fires do happen quite regularly, even if it's never happened to you.
