    If they used the reserve capacity to mask the degradation, I agree that we would not see it for several years without checking actual SOC with an OBDII app. But people are reporting the opposite. Capacity drops slightly over the first 2-3 years and then seems to level off.

    Also, once that reserve is used up (if Toyota was unwise enough to do that), the battery will degrade much faster. The whole purpose of the reserve is to keep the battery at healthy states of charge. It's the same methodology used in solar power battery management. Excursions outside those limits will accelerate capacity loss. It probably won't be linear once it gets to that point.

    Another factor is that people using OBDII devices that show actual state of charge are not seeing it go outside of the 13%-83% range it had as a new car. And the 2012 PiPs are still running fine.

    Hi all, I've been a Prius driver for quite a while, and have posted infrequently, mostly lurked. Now I have a shiny new 2020 Prius Prime.

    Here is my question: Can someone suggest a way to get real-time measurements, in terms of kW/100 miles (or any combination of electric energy per distance, I can translate offline), using an OBD2 reader? In other words, like my OBD2 reader can show my "instantaneous" mpg (going down when I accelerate, going up when I am going down hill), is there a way to get "instantaneous" electrical efficiency, that I can record through out a drive?

    I have an OBDLink LX, and there are about 30 gazillion PIDs that might relate to this. Any help or direction is much appreciated!

    Since you're talking about recording it, I assume you don't mean the instantaneous gauge next to the speedometer.

    I just got Hybrid Assistant and installed it on an old Android phone I scrounged up. I mean JUST got it working last night and I'm learning my way around it. You already have the OBD adapter they recommend. You might investigate it. Unfortunately for me, it's Android only. @john1701a makes very good use of it and posts lots of vids here and on his website, John's Stuff - Toyota Prius and more.
