Tell me if I'm missing something here. If I charge from 65% to 75% (let's say, for simplicity's sake the battery is 100kWh), 7000 cycles gives you 70mWh of charge. A 25% to 75% charge would require only 1400 cycles to give you the same total charge. Is this taken into account?

I love my oracle touch. Would not trade it for all the Starbucks coffee in the world. It pays for itself eventually. This is probably the best $2.5k I ever spent. Have mine for about 5 years now. Love it still.

What battery technology is this for? Li ion, lfp, solid state. Then different battery manufacturers tweak the chemistry for longer range or faster charging times.

Not of you have a LFP battery….

I think you need to be careful in comparing apples with apples Vs apples with bananas. Battery University (I know them well) are testing vastly different battery types, plus the significantly advanced BMSs these days ultimate in very different results and are absence in BU's analyses. I note that Nissan Leaf protects 10% of the battery so 100% charge is really 90%. Other manufacturers are similar in EVs. I also note that for cell balancing in NMC battery chemistries it is important to charge the battery to 100% every now and again (some say weekly, but I believe monthly is perfectly fine for low mileage drivers). See Video from a prominent battery expert in the UK (kzbin.info/www/bejne/h4Ozq5hqm5WaqbM). This gent truly knows his stuff, is well researched, well respected, a recognised leader in this area, and has Degrees up to PhD in this area. He factors in the variables that you have missed here for EVs. All that said, I see a happy balance between your advice and the battery expert's advice. I would recommend charging to 100% at least once per month (for cell balancing which is critical) and thereafter keeping things between 50% and 80% (which on must cars would really mean 40% to 70% owed to the manufacturers buffer).

Well, I’m one the low km/day kind of drivers, maybe 10km/day in average. So, it’s about 100km/week max. That’s 1/3 of my battery range and if I keep battery between 45-75% it means one recharging/week and, according to your chart, my battery would be 90% CR after 4500 cycles, or 4500 weeks, or nearly 86 years. That’s quite good battery life😊

Thank you very much. ❤

Nice video! Is this valid also to LFP batteries?

I doubt if many people use one full cycle per day in their EV. My understanding is that 1 cycle means going from 100% to 0% or the sum of several incremental charges equaling 100%.

So what about LFP batteries?

I like where you're headed with your analysis on this topic but I think you've stopped short of the desired conclusion. What I think most people will be interested in is how many days or total kms you will get out pf a battery given the 90% threshold and the different charging regimes. If you take an average car energy consumption of 20kWh/100km (and many cars may actually use a bit less that that) then you will use 40/100 x 20 = 8kWh per day. If you then calculate the total kWh you will get out of the different charging regimes and divide by the 8kWh you will get the number of daily trips. My calculations are based on my car with 80kWh (usable) battery which gives me the following: For the 100%-25% charging regime, reading from the graph we get 1,000 cycles. We are consuming 75% of 80kWh or 60kWh per cycle. Dividing by the 8kWh gives 7.5 trips before we have to recharge. Call it 7 (1 week) to make the arithmetic easier and more realistic for when you would recharge. If our battery only lasts for the 1,000 cycles, that means 7 x 1,000 x 40kms = 280,000kms and 7,000 days or 1,000 weeks which is over 19 years. Similarly, reading data from the graph and extrapolating as necessary, the other regimes give the following: 100%-40% 288,000kms and 7,200 days (nearly 20 years) 85%-25% 504,000kms and 12,600 days (34 years) 100%-50% 300,000 kms and 7,500 days (20 years) 75%-25% 600,000 kms and 15,000 days (41 years!) 75%-45% 576,000 kms and 14,400 days (39 years) 75%-65% 360,000 kms and 9,000 days (24 years) Clearly, avoiding the 100% charge is the key, and the stand-out winner is the 75% to 25% regime. Personally, I am doing mine with a 60% to 20% regime with the occassional 85% or 90% if I have a long trip.

One factor not taken into account here is dendrites - these are internal growths inside lithium battery cells. These can cripple cells or even cause a spontanious fire - totally at random. It might be a new car; it might be 10 years old, but if it doesn't short a cell and cause the battery to catch fire it will destory cells inside the battery pack and eventually make is useless; as time goes on; more and more will be disabled. Even older battery packs that used different lower energy chemistries that did not have dendrites don't last 10 years, lithium packs - probably plan on it being dead in under 200,000 miles no matter what, due to dendrite deterioration.

What I do with my Chevy Equinox EV 2024 is I charge it at max 80% from Sunday to Tuesday and I charge at 100% for the weekend....I charge with Level 1.

Cool, 95% of EV drivers could get 20 years out of their battery.

How about a follow up to this video with all the latest updates? Are there any dst charts which show 40-60% ?

I only charge to 65% and try not going below 40%.

Our goal is not to just achieve the highest cycles without factor in how far we drove to reach that point ( Usage vs Degradation) For 75-65%, though we got 8000 cycles, but we only drove 10%x8000 =80000 unit of distance (let's say your car can drive up to 300 miles. 1% of your battery can be driven for 3 miles, we define it as 1 unit). But for 75-25%, we have 50% x 3000 = 150000 unit. This is same as 75-45%, we have 30% x 5000 = 150000 unit. Even at 85-25%, we can have 60%x 2000=120000 unit. That's even better than 76-65% in distance when it all reached 90% capacity retention. Considering the lifespan of the chemistry inside, the battery degrades over time anyway. We're chasing the time while maximizing the cycles of battery. So the sweet spot for charging range would be 75 - 25% with less charging anxiety (charge every 150 miles, half of full range) , or even better 75%-45% ( charge every 90 miles) if your daily trip is extremely short. Or even a simple rule of thumb: set charge limit to 75%, charge whenever you feel like to, just don't let it drop below 25%

so charging to 70% with 20 miles everyday drive battery will last probably forever

I bought a Breville Oracle in 2016 (the original model before the touch screen). I remember agonizing over spending so much. Just one person in my household but I did do some calculations on when it would pay for itself. I love the convenience of being able to make a delicious latte in my kitchen without having to drive somewhere. I have often wondered what I would do when my machine dies. Well, the answer is I would buy another one. I have had mine now for going on 9 years and it has been nearly trouble free. I have a latte most days so it has paid for itself many times over. I am sure someone smarter than me could tweak the settings and it would make an even better latte but I am more than satisfied with my Oracle. Enjoyed watching your review.

thank you!

I keep mine charged between 50 and 65% usually but some believe it must be charged to 100% occasionally for cell balancing. Don't know if any truth to that but I guess it'd help the car determine charge % and range estimates.. I'm not real sure if I should do it though.

100 to 10%. 😅

I enjoyed your video. I have a Rivian R1T with the 135kW battery. I charge it to 70% and generally when it hits 45-50%. That seems in line with the graph and is close to the 75-45% SOC. What do you think?

Hoe turn turbo on my scootet

Thank you

I got the Oracle Jet and can easily remove the fan but cant for the life of me remove the shaft. When i grab on the top of the shaft the whole assembly rotates with it left or right. When I grab the lower part of the shaft it doesn't move at all. Any ideas?

How long should you pull up and wait after driving 40% of the battery capacity before hitting the road again?

Engineering explained, you tube channel covers this topic as well. He actually has a white board chart explaining what is actually happening at the molecular level of the battery cell. Super interesting, has about 3 million subscribers, big car guy, his net results were…… watch the video ,you will be glad you did

We just traded our 12 year old Prius C for a 2024 Prime. The Prime is our third hybrid but first PHEV. The C had 128,000Km on "the clock" and from the beginning gave between 4 & 5 l per 100Km (dependant on ambient temperature). Regards charging cycles; its battery was just under 1kw, so, it was constantly being charged and discharged every time it was driven. At about ten years, the battery would no longer gather enough charge to run the car in EV Mode (which even when new, was limited to 1~2Km's. But, even with that constant charge/discharge rate, the litre's per 100Km performance did not decline. The new Prime's Traction Battery is close to 13 times the "size" of the C's. It incorporates a charge "buffer" of (I think), 10% lower and upper, meaning there's 80% of usable charge. Yesterday, I drove the Prime 88Km in EV Mode and the Trip Computer indicated there was 6% charge left. The car would have exceeded 90Km on battery. This morning, the computer stated the range would be 91Km. For us, the Prime is essentially a BEV. After 5,000Km we have used just 1.5 tanks of fuel. Based on the length of service the C's battery gave, we have no concerns about the level of charge/discharge with the Prime. The Traction battery has a ten year warranty, we plug-in every night and don't worry about cycles.

Thank you!

The best way to recharge is to plug in and recharge every chance you get. The smaller the depth of discharge, the longer your battery will last. I set my maximum charge for daily driving to 50%, and I plug in every time I get home. Drive to dinner and home? 5% DOD, plug in.This is true because the smaller the DOD, the smaller the physical change to the size of the particles that are expressing or receiving the lithium ions, and therefore, the longer they go without splitting, cracking, breaking apart and becoming smaller. If I didn't have the same price for electricity regardless of what time of day I charge, I would recharge every night during off peak pricing.Either way, you want the smallest DOD you can get every time you use and recharge the battery.

Anyone know where to get a steering damper for a (zsnake,vreom, EFGTEC) 5600 dual motor.? I put wider bars with bar end weights and helped but not enough to max out speed

Where did you get that 90% SoH would be a limit for the battery to be usable? Battery warranties usually guarantees around 70% SoH. That's a low number, and the car would probably give unreliable range figures when the battery approaches 0% SoC. But 90% SoH? That should be no problem, otherwise why is the warranty som much lower?

Mate this is really good info, specially on my use case that I as well travelling similar than you. It looks that 75% at max is the nice balance of enough charge and looking after the battery, specially important is people is using DC chargers regularly. Whilst the ideal is to charge at level 2, 11Wh speed

I don't think a single manufacturer considers 90% the threshold for a worn battery. The industry standard is 70-75% I believe. I'm not sure why anyone would look to replace a battery around 90% as in a 300mi car you're still looking at a usable 270mi

Short answer: NO

Should probably give it to me if you still have it, i'm a 15 year old boy from norway who loves these types of things perhaps i could buy it off you :) im doing some summer works

So if I drive a total of 45 miles (72 km) each day round trip to work and back would you recommend charging each night to a maximum of 50% or even lower since I would only be using approximately 16% of my battery each day? BTW - I love your channel and the science behind each video!

I do this entire process with you ~every 6 months! This vid is 1 of the reasons I purchased this machine and I enjoy cleaning mine ‘along with you’ as you seem to have such a kind way. Thanks! ☕️

Very helpful! thank you.

I think it’s going to be time for you to reinvest in the all new oracle Jet

You had to replace anything

Brilliant

You still using the same machine

Nice video sir

Because most people use less than half the battery pack’s capacity each day, a new Swedish study charged cars up to 50%, and then charged them back up to 50% after use. They got spectacular improvements to battery pack service life vs. charging it to any other amount.

I enjoy your videos! My son-American, daughter in law-Australian, and grand daughter-both live in Melbourne. I'm in Maine, USA. :( I had often wondered why a KW of electricity is cheaper than a KW of gas and what I determined is as follows. A huge point in the coal argument frequently missed in the coal/fossil fuel generation of electricity is that a fossil fuel plant operates at 40% efficiency. While the avg ICE is about 25% efficient. So, conversion process is less costly for a fossil fuel plant. And then we have transportation of the gas to a station which is done by an ICE vehicle at 25%. Electricity transportation is done through a grid, 95% efficiency. These are direct factors in why an EV fuel is a third the cost. The production of fossil fuels involves mining/drilling which are the indirect costs I don't know how to quantify. But the damage done from spills and contamination is too much. We have solar, we use the direct path from the sun to fuel my wife's Tesla, she has not been to a petrol station in 5 yrs. Me, truck, aggravated there are no good truck EVs and have to spend time and money going to fuel up. The climate warming debate for me is insignificant. Earth at this point in time is cool relative to the life of the planet. 75% of the time earth has been warmer than it is now and there have been multiple cycles of hot/cold. I don't know who is right or wrong in the debate as to whether we are the cause but I find it hard to believe we are the main cause of CW.
