"Battery degradation is inevitable. But as technology advances and carmakers come up with better ways to improve battery life, it's slowly becoming a non-issue. That's what the statistics say, and that's what I discovered after doing a battery capacity test on my own 2023 Volvo V90 plug-in hybrid wagon, which I've owned for almost a year. My car is rare, and that's one of the reasons why I bought it in the first place."
"So I had to do it the old-fashioned way, by completely draining the battery and then charging it to 100%. By doing so, I discovered some interesting information that quickly explains why Volvo hasn't integrated a charging limit feature in its PHEVs. In all EVs, owners"
A battery capacity test on a 2023 Volvo V90 plug-in hybrid wagon shows that battery degradation is becoming a minor issue due to technological improvements. Volvo upgraded battery packs and rear electric motors on SPA-based four-cylinder PHEVs starting in 2022.5, affecting S60, V60, S90, V90, XC60 and XC90 models with Android Automotive OS. Volvo's infotainment and OBD outputs do not expose PHEV battery health directly, so full discharge and recharge cycles can reveal true pack capacity as reported by the battery management system (BMS). The BMS state-of-charge and voltage readings can differ from the instrument-cluster display. Volvo PHEVs lack a built-in charging limit feature; manual unplugging is required to stop charging below 100%.
