The black gives 75 x 4.4 =330 vs yellow 10*8.4 = 84 ! Charge once a week 4x+ every day.

2:37 So I'm not 100% certain, but I think a cycle here means expenditure of the full usable battery capacity... so if you have a 50kWh battery, one cycle would be counted every time you've used 50kW even if you used 10kWh per day and recharged that amount every night, for 5 days. In which case it would be incorrect to say 300 cycles represents less than a year of use. Almost nobody would do a full cycle every single day. An average use profile might be to ride 30 miles per day, with the occasional long distance journey maybe bumping that average up to 40 miles per day... assuming that equates to using about 12kWh/day, you'd be completing a full cycle of your 50kWh battery every 4 days, or roughly 90 cycles per year. Of course with that depth of discharge, and if you only charge to 65% every night, you're looking at 20-40 years of life for your battery pack... not taking into account temporal degradation, which they say is actually more significant than charge cycles. In this ideal charge/discharge usage scenario, I'm pretty sure temporal degradation would be the limiting factor?

Great video

I have a BMW 2014 i3 with 130000 km. The battery has very little degradation and achieves close to its original capacity. I live in Canada where the temperature ranges from -30 oC to +30oC and i plug it in every day after use at a wall socket. BMW was wise enough to build in a buffer so that even if charged to 100% it's actually 80% or thereabouts. Hence, a long lived battery.

Also keep in mind that topping of your battery to 80% for example every day has less battery degration then say a larger top up charger every 3 days or so. This is because a small top up is less stressful.

Well, just got my battery SOH check after one year, and 12,168 miles. I charge daily, and keep the battery charged to 60%. And it typically recharges when reaching 50% to 55% - back to 60%. My fast charging is minimal, easily less that 15 times per year. I’ve been guilty of fast charging to 90% about 5 times, and 85% 7 times, and the remainder up to 80%. My battery health check determined I had lost 3% SOH. This may not be a big deal. But I’ve babied the truck, and been extremely careful on freeways (averaging 65mph). During the first year, is it normal to lose that much? I’d love to get your feedback. I truthfully thought I’d see less that 1%, considering the small amount of miles, and my care for the truck. It is a 2023 Ford Lightning L ion battery. Please let me know. Thank you

How will the batteries react if I charge to, lets say 95% for a longer trip once in a while?

I did more calculations based on the graph or charging cycles, you have to factor in how many KM or miles you get out of a cycle too, for example , if a battery can do 500km from 100% to 0%, then every 1% is 5km , then you multiply the 5km to how much percent you use from the battery and it gives you how much range per cycle, according to my calculations the optimum is 75 to 25 %

3 years later and this is still very useful, thanks! Think it's somewhere else in the comments but at 2:30 they're not left handed any more, you just pull out. Everything else is the same though (on mine anyway).

Why does the manufacturer of my EV suggests turning off 1 pedal driving in snow and icy conditions? If it’s just like antilock braking why would this be the case?

20 years... I'm on a 3 year lease. After that it's on to a '27

Thank you

Yes, Thank you. Very helpful.

great info, so in conclusion, charge everyday at home, on level 1 or 2, between 45% and 75%

Good video. Question, can Zappi control the rate at which the car charges at e.g. 3kwh rather than full 7kwh? Because of solar didn't generate 7kwh or more car could draw power from the grid when charging during day?

13:30 Trying to interpret the chart, it's not clear. But I think that 1000 cycles of 100%-25% is equivalent driving to 750 cycles of 100% DoD. And 8000 cycles of 75%-65% is equivalent driving to 800 cycles of 100% DoD. So not really much improvement in battery life. The measurements that make sense are comparing the same amount of discharge which is? driving equivalent to each other. 100%-40% and 85%-25% are both 60% amount of discharge and you do get more cycles of 85%-25%. 100%-50% and 75%-25% are both 50% amount of discharge and you do get more cycles of 5%-25%.

Nice presentation. Sounds sensible from every perspective. I understand that your data pertains to NMC . If your hypothesis is correct , it is likely to be the same for LFP too . What is your opinion?

All we need is more mechanical infrastructure and more knowledgeable mechanics who can work on high voltage batteries as they do on ICE engines. One should be able to buy his/her EV and just drive like a normal car, and if it's break you fix it. No one is lecturing people about their engines. I drive and charge when I need to. Battery prices are falling , and there are many in the scrapyard . You can replace bad modules/cells, and you are back on the road. All we need is more mechanics so people have choices and access to cheap repairs.

thanks! you do make me rethink my charging habit. Also, people don't understand , for example, 2024 model 3 LR / Performance have the NMC90 battery , which degrade much faster than NMC811 at higher SOC. Model S battery degrade much slower due to 1. higher capacity (maybe more buffer built in) , 2. lower Nickel content.

Almost like customizing is more useful than one-size-fits-all ... which only actually fits e one it was designed 4. Who wd hav thought. Good video.

If you charged your battery to 100% and only used around 20% of it's charge each day, you would not need to charge your battery every day, you would only need to charge your battery every forth day and still have 20% charge staying in the battery. I think a battery being charged every forth day would last longer than a battery being charged every day.

Great strategy until the power goes out in storm prone areas. Like having a 1/4 tank of gas.

I have a 2023 Ford lightning and even if you tell the truck to charge overnight to 100% you never really are because ford reserves a portion of that battery that you can’t use

10% takes 7.5 times more cycles than a 75% discharge, so data is misleading.

Thank you!! Great video… just got my messages to sync

How about the best amps to charge at?

Do one for LFP please!

But surely 5000 x50% will give you more kms than 8500 x10%.

Really hope that we see bi-directional charging support for older EVs. Not sure if that requires a hardware change or is at all possible, but would be awesome if my EV could be upgraded to that.

Hi, thanks! Will the new standard also include NZ? Normally we follow you guys? Cheers

Whilst the standard might be being set, are there any models that already support bidirectional standards today (apart from ChaDeMO vehicles)? And is it AC or DC bidirectional?

I got solaredge system and two evs , a Tesla model 3 ST and BYD dolphin a huge system and a 10 kwatt solar edge home battery. What do you know and think about the solaredge DC bidirectional charger??

Our Solar has more than covered its own cost in 4 years , We just bought our first EV and its fantastic . Being able to send a lot of the energy into the Car instead of back to the grid means we save even more money . Seriously considering adding another solar array .

I have been looking forward for this to become commonplace in the UK :)

Yeah... But these numbers are under perfect weather conditions, we the North, Canada climate is different than the 20° mentioned on the paper, it's a good idea but not applicable for all weather conditions.

Thanks man! Hard to find this information online. God Bless

When I bought my car I was considering a BiDi ready one, but the additional cost for something that would be maybe in the future work was too high. Same goes for the needed DC wallbox and energy management system. It wouldn't be much usefull for me either. I need the car for my commute, so there wouldn't be any energy stored during the weekdays and sometimes I visit friends and family on the weekends. I already only have one day for charging with the sun each week. It's barely enough for driving, but not as a storage. Now I got a 15 kWh battery system which is always home and can be used during the day, when my car isn't home. I did cost around the same as a BiDi system but it's much more useful to me.

Can you programme the machine to increase the coffee dose?

Another great video mate. Looks like there’s a bright future in electric living.

So you can extend the life of the battery almost to infinity if you park it up in a garage and get the bus 🚍.

This science should turn into a battery management software project. I also think than an auxiliary easy to replace battery (a few kg.) can be added to the system in order to smooth things out for the main battery. I imagine a cheap lead-acid battery used as a buffer (spend first charge last fashion..) in order to keep the lithium battery say within %40 - %70 range. It can be replaced at every service with a new one and recycled. With proper software it could reduce the stress. Could be a good design decision to transfer the burden to a more serviceable (or replaceable) part .

Excellent clip which solves so many issues.

Thanks for posting that. I have a 16” saw with this problem. It’s a different brand but looks like it was made in the same factory. Can only turn the band wheels backwards to adjust blade tracking. Did you work out an electrical solution to disengage the brake or remove it once out of warranty?

I bought a carbon oxy 10 with dual 1000 what motors its capped at 40kmh idk why im trying to unlock it

Question: What is better for the battery: Charging 110V 12A, or 220V 22A, or 42A?

Question: What is better for the battery: Charging 110V 12A, or 220V 22A, or 42A?

Love how you cut right to the chase and breakdown all this technical info into something I can understand!!

What about people who don't have home chargers and usually charge once a week? 😔

Would the Tesla M3 Highlander be a Lithium battery (LFP one)? Under the study’s standards?

Best to charge from 25% or 45% to 75% according to the chart.
