    I thought the only vehicle that meets those requirements of a BEVx is the BMW i3-REx. They needed to reduce the capacity of the engine to meet the requirements.

    CARB regulation[edit]
    According to 2012 Amendments to the Zero Emission Vehicle Regulations adopted in March 2012 by the California Air Resources Board (CARB), a range-extended battery-electric vehicle, designated as BEVx, should comply, among others, with the following criteria:[2]

    So the Volt does not meet that requirement. The fuel tank is too large.

    Ahh I forgot about the i3 REx. Yes.

    Ok so I don't understand your statement or question then.

    The Prime is labelled as a plug-in hybrid, right? Isn't that correct? It's not a range extender.

    You said the Prime is not happy with the same frequency of charging and discharging as the Prius. I interpreted that to mean the Prime is designed to be primarily plugged in and the engine just extends the range like a BEVx rather than being designed to operate in hybrid mode for long times like a PHEV.

    I don't know the technical details, I just know my Prime Advanced is easily quicker in EV & Power mode, than it is in HV & Power mode. This is for acceleration from 0-50 mph, and yeah I know, it's "seat of the pants" testing. I also love the car's performance in EV/POWER mode for going through twisty bits and hill climbing; the car just loves to be pushed and is very stable and well-controlled. No problem taking turns marked 35mph at 55mph; the Michelin Defenders don't even squeal! I charge my car from almost 0 miles to full charge as much as 3 or 4 times per day.

    Ahh ok. Hmm, let's see how I can explain it with my limited engineering knowledge lol.

    I think the takeaway point was that even though both Prius and Prime use "li-ion" batteries, there are different types of li-ion batteries. Toyota simply used chemistries that matched their intended use.

    The Prime is fine working as a hybrid since, in the hybrid mode, it's using that smaller portion of the battery. (Also, the owner's manual says somewhere that if you plan to park the Prime for a while, leave it uncharged in the HV portion of the battery).

    What I think Toyota meant is that the Prime's battery isn't meant to be fully charged and discharged (man I gotta watch what I say lol) like a regular Prius does. It's meant to be fully charged and used up like a plug-in hybrid would. Hopefully you see the slight difference in application between the two.

    Or put it another way, a Prius will use its range of capacity more frequently than the Prime.

    Otherwise, the Prime is very much like a Prius with a bigger battery so it's not a range extender :)
