2021 - 2005 = 16 years. That is a BIG difference in TSG Technology!

congrats, paradigm shift for prius. you didn't miss much in gen 3 except some headaches.

all the best!

 

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

 

What's a TSG?

 

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.

 

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.

 

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.

 

okay, i can breathe again

 

do you mean after the wall charge has run out?

 

Picture Please..!

 

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.
