From what I’ve seen in owner reports and technical discussions, this battery upgrade does seem to be possible on the Volvo XC60 plug-in hybrid models that originally came with the 11.6 kWh battery, replacing it with the newer 18.8 kWh pack used from around model year 2022 onward.
In the cases I’ve read about, the physical replacement was described as almost plug and play, with no major structural modifications required. Even though the newer battery offers more usable capacity and greater EV range, its external dimensions appear to be very similar, which is why it seems to fit in the same space without major hardware changes.
That said, the swap is not just a mechanical job. In pretty much every report, people still had to use Volvo VIDA to perform the required software updates, adaptations, and module recognition procedures. Without that step, the car may not properly recognize or manage the new battery pack. So even if the hardware fits, the software side is still critical for correct charging logic, battery management, communication between control modules, and overall hybrid system operation.
I’d expect the same general principle to apply to the XC90 T8 / Recharge as well, assuming the battery, control modules, and software versions are compatible. But since this is a high-voltage hybrid system, I’d definitely recommend confirming compatibility by part number, VIN/chassis, module generation, and VIDA software requirements before attempting anything.
