Dealer can test it and balance it through the software in car. They will not replace individual cell though.

Yes - official dealer won't change cell's - and they do not have a better or more powerful ones. There has to be more powerful cell's it's only matter of time when someone does it...

Some parameters of the high-voltage battery are accessible with the Car Scanner Elm Obd2 app for iOS and Android.

Volvo SPA profile in Car Scanner shows HV battery voltage, current, instant power kW and real state of charge SOC (you can see the top and bottom buffer).

App shows the 12 aux battery voltage as well.

Was there problems? Battery box is "easy" to take off. Cell's are easy to change. Cell calibration can be done even with tiny charger and a bulb (?).. So after it may be issue with software if it gets angry when there is too much power? Haven't done my self and won't do, but I read somewhere - a guy fixed unfixable battery pack too. (not Volvo).

Have you any idea, is it possible to fill the box with more powerful cell's or is there better cells..

And does someone have even a strong hunch how much of battery power is limited by software to make battery life longer and "hide" wear from consumers? I think Volvo xc90*s battery's are from LG
There are couple guys from Czech Republic and doing all kind of software changes..

That's the difference between net and gross battery capacity. As the article points out, net on the MY16 and 17 is 9.2kWhr and net (usable is 6.5kWhr although I think by the time they hit production it may have been closer to 6.2kWhr). It's primarily to prolong battery life but also it gives buffer to allow for degradation over time. All EVs have a gross and net rating. I recall Audi's first eTron had a overly conservative net capacity and after they had some on the market they dug into the gross capacity via an update to allow for better range.

Those Czech guys cant go in these yet.. Rica can, I'll contact them if they have some plans for electric drivetrain. (Rica is one engine software optimizer - I'v had rica's software in all my cars since 2007..)

Edit: I think it's not the same with T8's - these already have lithium batteries?

Hi, Hybrid guy does upgrades to Prius... Big difference in weight and power.
T8 uses lithium battery already, but you may want newer, better lithium battery that is higher capacity. :)

Yes I do - just got too carried away when looked Prius upgrade numbers.. Less weight, more power etc. Have you heard if anyone has done upgrades.. How it's done in new long range models? Bigger batterybox or better cell's?

With so much battery advancements going on I agree there will come a time when owners can retrofit batteries (solid state please!) with the help of 3rd parties - unless Volvo decides to more fully live up to its sustainability pledge by preventing more waste and making longer use of current items!

Yes, I'm challenging you, >>> Volvo <<<, to retrofit our SPA batteries when the time is ready!

And that would be around 8-10 years from 2015, making it 2023-2025. Hope you, Volvo, are working on a sustainability solution right now!

Volvo is doing it right now, putting 18.8Kwh battery in same T8 body. :) We don't know if they had left spare space inside the battery pack or the new cells are higher capacity.

Fyi. I havent test drived the 2022 with 18.8kwh battery yet.
But it seems that space was taken from underneath the middle console. Shallower storage space and removed drive selection wheel. But this is just my speculations atm.

I am really looking forward to the possibility to tune or upgrade the battery for the current models. But for my2019+ someone need to crack the Denso/freescale first..

The driving mode wheel is removed from all new models, B5 B6 as well. It is not T8 related. The arm rest storage was shallow already. Only several cube inch space could be saved by completely removing it, far from space needed for bigger battery.

You would't understand a word.. Some electrician fixed hybrid battery w/o expensive tools. He said that every cell should have same voltage and how to do it - charge individually and if you over charge you may use even a bulb to discharge..
