Very specific situation question (about heat and charge level)

Agree here.
Simple test: stop the car while HV battery shows, say, 5 bars. While stopping, request cabin heating, you will see battery charging while ICE is on.

 

The battery indicator is solid in color while EV range is possible. Once the EV range is gone, the indicator is segmented like it is in a non-plug-in Prius.

 

The only time I've ever seen EV range replenished is after some heavy regenerative braking on a long downhill stretch of highway. The ICE, by itself under normal conditions, has never added any range to EV.

 

This is not exactly true.
You have EV range with 8 and 7 bars of the "segmented" indicator. At this stage, even short downhill or ICE operating while stopping will replenish some tenths of an EV mile. Zero EV is when the charge is going down to 6 bars (and then EV mode switches to HV mode), I think this represents about 23% SOC. However, it will go back (long downhill) to EV mode at about 26% SOC (however, you can manually change to EV mode earlier - after indicator changes from 8 bars to solid battery indicator and EV miles will re-appear).

 

Maybe in Israel you have that, but in mine bought in the US, the EV range remains solid and becomes segmented after the EV range has been depleted.

 

Your words, not mine. The ICE does not charge up the EV range when idling or running normally once it's depleted. The only time I've ever had an EV range added was on a long downhill where I was using regenerative braking. Never at a stop light, stop sign, in the driveway or on the highway just driving along with traffic.

 

I am out

 

Yes, with EV range still available, it will regen additional miles. Once it's depleted and in HV mode, I've never been able to get any more EV range except as noted earlier.

 

Don't run off, it could be the US version is different from those models produced for other countries.

 

Do not think so, the situations I was describing were already described by others in this forum, they can also be found in the manual.
Try it, when going down from 'solid' battery icon to 8 bars segmented, you are still in EV mode and you have EV range (about 1 mile?).

 

I would charge up to full. I don't think the ICE recharges much EV except when you first switch to HV from a cold engine. The infographic clearly shows there is some charging but it is so incremental that you only see the charge level rise when the meter switches to bars. So unless you head downhill from the start of the trip, I think you would have plenty of battery capacity to absorb leftover ICE energy.

Page 268 in my manual clearly shows the hybrid battery status indicator displayed solid and not segmented when in EV mode. In HV mode, the display becomes segmented.

Perhaps we're discussing something else and I've gone off track. I'm really not trying to be disagreeable though looking back it would appear to be so

 

Manual has graphic description of all situation with explanations. Its page 75 of my (European) manual. Try to locate it (Hybrid battery (traction battery) status)

 

Yes, it's on page 59 in my manual.
