SoH battery PHEV calculations - Henk{GP} - 09-02-2025
Hi there,
A noticed an slight increase on SoH of the PHEV Battery (10.8 kWh model / 6 years old). Current report 83,1% and last report 82,7% months back. I am little surprised and I guess I should be happy it reached some sort of stable level.
Can you share anything on how Orbit retrieves or calculates this value?
I also found VIDA has been upgraded to compute and generate SoH certificates from MY21 onwards, so Volvo modified their SoH calculations probably too. Can you state something about this too? Orbit probably is more close to the legacy calculation of VIDA?
Thank you.

That's an interesting question, I'd also like to know how Orbit does this calculation.

OrBit will be providing the vehicle calculated value returned when the vehicle is queried via PID. It’s possible that Volvo has an updated the calculation algorithm for display within VIDA, but that would require investigation.
