    Picked up a brand spankin' new Ltd last night. Midnight Black Metallic. WOW! There has been a huge change, over my last 231k miles. I'll be going to school on this sight again. I sure learned a lot about my Gen 2 here. Gen 4 is fascinating me.

    Congrats!! It's quite an upgrade, isn't it. Don't forget to update your profile info, btw.

    Yes just picked a 21 up yesterday. While I never owned one before, I did drive a few older ones, and would never own one. Drove like crap imo

    It is a typo. "G" is next to "H" on the keyboard. THS was the name/trademark of Toyota's hybrid system before it became HSD.

    This car is amazing. After reading through Prius Chat. I am still confused on the modes of EV. I have a 26 mile commute each day. I am trying to only run on the battery on surface streets for my commute. Mostly so I don't over use the battery. After a round trip, the best I have done is 13% battery left over as I plug in at home. I have no more than 10 miles of surface streets. How can I force the engine to charge the battery at 65 mph?

    you're thinking of the prime. driving in ev will hurt your mpg's though

    This is confusing. The thread is in the Gen 4 forum and your original post makes no mention of a Prime. And, your profile still says 2005 Prius II. But here, you mention plugging in.

    If it's a Prime, it's meant to be driven in EV mode whenever possible. If you drive farther than the battery can take you and get to your destination with battery charge remaining, you're wasting gas.

    Also, if it's a Prime, please report the thread to see if @Tideland Prius can move it to the proper forum.

    If it's not a Prime, keep your finger off that EV button. But then, if it's not a Prime, you're not plugging it in. :D

    Sorry to confuse anyone. I have a 21 Prime and an 05.

    The prime will not be hurt by driving it in any of the modes. The computers take care of everything. If you have 13% left at the end of a 26 mile round trip commute, then you are doing well and using it exactly as it should be used. The car defaults to "EV" mode when you start it, and keeps it there as long as possible. It only kicks in the ICE when you exceed 80 MPH or when the battery is depleted. Once the part of the battery reserved for EV mode is depleted, the car runs just like any other hybrid.

    You can force the car into "charge mode" while driving by simply holding the EV/HV button down for 5 seconds or so. That will keep the ICE running until the battery is over 80% charged. There are few instances when forced charging is desirable.

    I've read a caution on here about unplugging it after it charges if you are not going to drive it for weeks. That keeps the charging hardware from running down the 12V battery. Other than that, it takes virtually no special handling.

    "Charge Mode" sounds like a hack. I love it. I am surprised at how long the Prime wants to stay using the battery. Gen2 would run the ICE almost all the time at highway speeds. But would keep the battery more charged than the Prime.

    Yes. I would like the battery to NOT completely depleted, on a commute day.

    Why? Isn’t the point to maximise the EV charge to reduce the use of gasoline?

    i'm back to confused. the 2005 has no wall charge, and yet you say it retains more charge than prime

    They are saying that the PERCENTAGE of charge that remains is higher on a hybrid, even though the battery is much, much smaller than the plugin versions.

    Without using exact numbers.... There is one traction battery in the Prime, and 20% or so is reserved just for use when in hybrid mode. The next 60% or so is reserved for driving in EV mode. The last remaining capacity is used to provide a buffer to capture energy when braking as well as to prevent damage from overcharging / over-discharging.

    On the 2005 hybrid, the small battery did exactly the same things. It had a lower and upper level of charge, and it kept the battery between those limits. The "usable" portion of the battery was something like 60 percent.

    It all boils down to the fact that the car is not just set of wheels and a motor. It's a complex system that has been designed to optimize usability and minimize pollution. Part of that "usability" is long service life that comes when you don't abuse the components.
