    If the ICE were disabled due to no gas, it couldn't start up. If the gen set were disabled due to no electrons, it couldn't start up. If you 'refuel' either/both, then either/both can start up.
    ie; semantics (defined: the cognitive structure of meaning ... but we can then beat the meaning of 'meaning' into the ground as well, is suppose) .

    I can't believe I let myself get caught up in such a silly semantic argument.

    Funny thing happened on my way home a few minutes ago. I ran out of EV, so ICE ran for a couple of minutes for the first time in several days. I coasted down the previously mentioned hill, during which time the ICE shut off. The car switched to EV mode, all by itself, and I drove the last mile home including a couple of blocks uphill, on EV without the ICE restarting. I didn't push any buttons, and BTW, the A/C was on the whole time. Is mine the only one that works as shown in the manual?
    As for the argument over semantics, it was because you said the EV mode was " disabled" until the button was pushed to enable it- incorrect information.

    "Disabled" in this sense, means "deliberately prevented from working." I understand that it could also mean "broken down" but that's not the intended meaning.
    Sorry for the confusion.

    Here are my observations:
    When in EV mode, and EV is depleted, Prius goes into HV mode. EV button non-operational.
    While in HV mode (due to depletion), if enough energy is recovered to top off battery and allow EV mode, Prius goes back into EV mode.
    While in HV mode (due to the EV/HV button press), energy is recovered to top off battery to allow EV mode, Prius does NOT go into EV mode.
    So let's say "EV mode not allowed" when there's not enough juice. I think that's essentially what the car says on the display. It's not disabled, it's just not allowed at that time.

    Praying with Red Flag Warnings in SoCal that I didn't continue any flames. :)

    Thank you, and well said. If I don't press the button, the system works much like a regular Prius, switching automatically in order to operate at maximum efficiency.

    2002 Camry SE factory air -- the compressor clutch relay was a known bad part that would cause the AC light to blink. Workaround was to take the relay out and bang it against your palm. The fix was an $8 relay on the interwebs or a $75 Toyota part.

    When running AC(cold), does it start ICE? Mine doesn't, I turn on my AC all the time and it never starts ICE. Heat however would start ICE every time.

    The A/C system is electric. It uses the battery-pack for power.

    Therefore it doesn't start ICE or? What are you saying?

    In fact, all Prius models starting with the Gen II use an A/C compressor powered by the traction battery. If the state of charge in the battery gets too low, the ICE will turn on to put charge into it. My 2002 Gen I powered the A/C with a conventional belt from the ICE, so the ICE had to turn on when A/C was needed. :(

    In the PiP, heat comes only from the ICE.

    The heater uses coolant from the ICE, which is warmed by combustion. This is speeded by running coolant lines through the exhaust system.

    I know a case has been made against using electric power to heat the interior, but here's another way to think about it: It should theoretically take roughly the same amount of energy to raise the interior temperature by 20 degrees as it does to lower it by 20 degrees. The Prius uses electricity to turn a compressor which compresses refrigerant, and circulates it through a condenser and an evaporator. Electric heaters are basically 100% efficient (waste heat = heat) and air conditioners are not 100% efficient. I don't know the exact number, but it's definitely lower than 100%.

    So this leads me to the question: why does the Prius use electricity for cooling, and the engine for heating? The relative efficiencies would seem to argue for the reverse.

    GM recommends with the Volt, using the seat heaters in the Winter saying that it's more efficient to heat the person rather than the entire interior.

    The ICE already provides the heat. An electric heater would be an extra component that adds cost and weight. I believe it was included in the prototype PiP but was removed in favor of heated seats.

    Many thousands sold, so there will be at least a few.

    It is true that electric heaters are 100% efficient. But that is based on electricity in and BTUs out. An A/C is a heat pump and works on very different principals. It is moving heat not creating it, thus comparing efficiencies is not appropriate. A (good) heat pump will move much more heat while consuming the same amount of electricity as a resistive heater. So rather than use a resistive heater to heat the PIP a better choice would be to run the A/C heat pump, but reversing the hot and cold sides...it is probably 2-3x as efficient.

    Like a regular hatchback, the PiP has a small heating grid in the HVAC box. About the only thing it's really good for is starting to demist the inside of the windshield.

    me? i never get bored of plugging in. in fact, the more the better! (i'm not even going to ask how we got from evse's to interior heat.):rolleyes:

    One story of a similar situation. At a some sustainability fair, a gal set up a small solar panel to power cell phones. It had 115VAC outlets for the cell phone chargers. Soon enough another gal saw the outlet and quickly returned with an iron and a bunch of laundry. Hopefully, most folks here can connect the dots of why a testy discussion ensured of "WHAT ARE YOU DOING!".

    Your are very correct about someone using a PIP ESVE cable on a future BEV X. But I expect the cable owner attempting to sue Toyota for a SLOW charging cable is the best outcome of that situation.
