Question about Inverter coolant temperature

Newbie at Prius, just bought a Gen3 2010 about 2 months ago.

One of the first things I did was to get a little generic Bluetooth ODBII reader & buy/download TorquePro.

So, on to my question.

I note that the Inverter temp tracks pretty well so far with the ambient temperature INSIDE the cabin, increasing by about 10f over the course of my 45-minute commute...which is all fine & good in the fall & winter when the temperature's low.

But what about in the summer? Is there a max "healthy" temperature for that coolant? Because in the Central Texas summers, it's not unusual for the cabin temperature to reach and sustain temperatures north of 140f.

Here's a chart of ambient (outside) temp and the effect it has on cabin temps. And THIS chart only goes up to 95f ambient.

 

I'm less worried about "when stopped" (as in "stopped in traffic"), than the fact that Yoda will sit parked for most of the daylight hours in direct sunlight...which can get (and stay for long periods) over 100f.

 

Yeah...my concern was...I drive this car mostly in the evening (so right after the heat of the day) and first thing in the morning (not as much of a problem).

So...after sitting the entire day in 100f+ temperature, the internal temp of the vehicle can reach a sustained 160f (no-shitting hot enough to cook food). Which, since it's sustained...means EVERYTHING in there will be 160f before I even start the car (meaning that coolant too, as well as the big battery under the floor).

Hence my question on what a healthy temp for that stuff is.

Also, I haven't seen an entry for traction-battery temperature in the Big List of Codes on the TorquePro page. THAT is something I'd be interested in monitoring.

 

Hmmm...I thought I'd looked through the whole list, but maybe I missed that. It's a LONG list.

And I remember loading the PIDs from that file in the TorquePro forum.

 

So...I guess then, my more pressing question then should be...what is a healthy continuous/operating temperature for the Traction Battery?

...given the above, ambient temp highs, greenhouse effect, etc.
