Hybrid Battery replacement T8 Recharge

[erikssoneee]

Hello,

My V60 T8 Recharge recently got diagnosed with a bad cell/module inside of the hybrid battery pack.
The quote from volvo to fix this is quite harrowing at 5000€ ish.

I wanted to see if any sort of DIY would be possible and if so what route to take.

I concidered buying a working battery from a scrapyard/wrecker here in Sweden or in Norway, There seem to be quite a few to pick from.

Could I get a battery with the same part.no in working condition and swap my BECM into it? would that be plug/play or would I need to do any other work to get it working?
Alternatively Load the software on to the BECM in that 2nd hand batterypack, or would I need a new BECM from volvo anyway?

If those are not an option could I swap the bad module in my pack for a good one out of another pack? 
If so, would I be okay verifying the battery voltages across all of the modules only using common meassuring tools such as a multimeter?

I guess I'm looking for any sort of knowledge or advice on the matter!

All help is highly appreciated! ?

It's not covered under the recall Volvo sent out a while ago? Guess the shop already checked that though.

What they said is that the battery warranty lasts until 162.000km and my car has done 167.000km
So I was not under any coverage apparently... Do you have any more info on this recall?

But seems to be more about a potential fire hazard than single dying cells :/

I can confirm that this has been done on my 2015 XC90 T8.
I am currently running a hybrid battery from a 2021 XC90.

The previous owner performed the swap. The original hybrid battery had a smaller usable capacity.
After the swap, the car initially refused to start because the Volvo software still expected the old (smaller) battery configuration.

A Volvo specialist updated the software using VIDA, and after that the car started normally.

The State of Health (SOH) of the replacement battery is 100% — so in practice I now have a nearly new battery. It came from a damaged 2021 XC90 with only about 20,000 km on it.

So yes, it can be done.
But you will likely need someone with VIDA access, as a software update or parameter adjustment may be required.

[color=#ffffff]If you can arrange that, it might be worth trying.

I've heard of swaps to the middle size, like you've done. Sadly not to the biggest one as it apparently has a different physical size. 

But nice to know it's doable
