Weekly Update 21.12

Not much, what Patrick is talking about is self-discharge rate. It is not degradation rate.

Degradation rate is affected when battery is too high/low in percentage for a long period of time.
I’d imagine most batteries, unused is stored at 50-70% percentage, or 100% really if you’re expecting a long as sit time. Either way it doesn’t matter.

Keep in mind the chart are constant with temperature and charge rate. It’s not like sitting on/off a charger.
So basically what I’m saying is the 25 Celsius and 96% after 1 year is the likely battery state left if the V’s are shipping in 2019.


Anyways, with the past forums in 2017 I was more psyched about “a battery limit option [BIOS & hardware] @50-80% battery when plugged-in” for the V, because many people can use it as a desktop replacement (at home/office) and from the chart, if you notice that:

  • a long 100% charged rate isn’t healthy for your battery, nor
  • discharging/recharging a lot, daily.

With the V, I’d hoped that Eve would take this feature seriously (since I/some people on the forums were concerned), but nope Even the CEO downright ignored/skid over the question, and replied with just: The V will not disable/overcharge over 100%, guys! (Well that’s what every now does, wtf…).

Even f’in Microsoft Surface, the guys whom I complained about on battery health/charging finally came in sense on 2018. Like any othe OEMs who has battery health/limiting option (e.g. ASUS, LG, Samsung, Lenovo, Dell etc. even TESLA cars)

People who used SP3 normally was doing great with 15-20% (or less) degradation for 4 years, but the ones who plugged it in most time fared worst. They [MS] finally realized, after 4 years of Surface Pro 3 (released in 2014), to add-in the feature (KUDOS I guess).

I finally caved-in and purchased SB2, because from the track record/and this coming to a feature, my battery would at least be secured for 4 years.

With the V, idk. @Rzabadabadoo; if they sourced a good Li-on battery manufacture, they’re in luck; but would probably receive complaint 2-3 years from now. An easily available money business decision that twarts “battery replacement complaints”, but Eve ignored it… (it’s like a case of anti-vaxxers.)

thanks for the research and explanation :slight_smile:

Time will tell then.

Everyone also needs to remember that the batteries were not made the same time as the V tablet it was put in. They put them at a storage voltage/charge amount after they(batteries) are produced and they aren’t going to change much from that when they are used to run tests on the V during production. They will never be even close to being fully charged when they arrive (I have gotten two now).

Time the batteries have actually been sitting is incalculable. It’s going to be vastly different for each shipment of batteries based on when they were originally made and when they were finally used in a production line.

The bottom line is, its not going to make any kind of difference any time soon. Like 5+ years from now soon. You don’t need to worry about the battery to actually start degrading until after you receive it and start using it regularly. I personally have left mine sitting off on my desk for well over a month without turning it on and it was still at like 98%. Even after using it to run Maya LT on a regular basis for a year (plus the several months before that just using it for office work) and the battery will still last about 4.5 hours+ essentially the same as when I first got it.

To make it clear, all electric cars are configured this way, its not exclusive to Tesla. Electric car batteries are slightly different than what you see on portable electronics, since the battery replacement costs a fortune there, longevity is deemed much more important than density when it comes to electric cars.

They have different chemistry, different thermal management, and as we just discussed, different default charge level

The Tesla batteries are cylindrical 18650 type sitting in glycol, where most laptop batteries are flat. They may have very similar chemistry but their shape and application is poles apart. The EVE batteries would be at least a year old from manufacture remembering they promised March 18 delivery. It will remain to see how they last, I think it will be a year less than what IGG backers received, say 3-4 years instead off 4-5 years.

Hopping with fingers crossed and believing in leprechauns and tooth fairies I’ll receive my Eve by March 19

Ok, this is something I didn’t know. Does not happen often. Because it’s implemented in uefi, I wonder if it could be implemented with Microsofts recently announced FaaS. Project Mu

I am not sure how to replace the uefi implementation of the current V to be able to support this feature and other requested features like the battery status indicator when off.

I am a proficient software engineer but haven’t touch this sort of development yet. Anybody up for the challenge, I’ll look into this after Christmas.


#29

I hope this will soon gain (specialist) traction, it is a very interesting pathway. :star_struck:

Oh, I forgot: it is worth a new topic!

Still curious about warranty replacement EveV’s. I had two 25ths of December waiting for a late IGG EveV, and seems I get the fun of warranty waiting for another 25th. The support case has been open 9 months now, when do I realistically expect to see a replacement device? Being left on the tenterhooks of zero information is not the most helpful. You could update all the warranty cases with a comment in a weekly update… But you also have multiple times told us warranty cases to contact support. But support doesn’t contact us… So what is the point in emailing support that doesn’t even respond.

What’s this about, are we getting an update today?
