According to the 2010 Repair Manual for Normal operation: While driving at an ambient temperature of 77°F (25°C): 59°F (15°C) to 230°F (110°C) With the 90 to 100 F ambient temperatures that we have been seeing lately I have been seeing around 150 F.
so the scangage should have a fIC gage? or what would it be? I flicked through the gages and didn't see anything like ICF or fIC.
^^ No, its not there either. Look for Adrian Black's Prius-specific XGauges pointers here, or go to the Toyota-specific list on Scangauge's website, which will end up at the same Google spreadsheet page.
It's on Andrian Black's Prius Gen III XGauge Spreadsheet version 1.2- you need to program it into the scangaugeII as a user Xgauges like SoC or BtT. row 39 Inverter MG1 Temp (name=I1C) row 40 Inverter MG2 Temp (name=I2C) row 41 Inverter Coolant temp (name=ICF) (background: one might monitor Inverter temperatures for overheating if the inverter cooling air intakes were blocked to increase thermal efficiency AND the Prius was being driven at superhighway speeds intermittently.)
I meant for him to learn how to enter XGuages into the SG by means of the manual. I assumed the spreadsheet was already pointed out.
@ spiderman, I had a doofus moment. sometimes you have to hit me over the head with it for me to understand what you mean. I don't do subtle very well. LOL I do appreciate the reply.
Are the "intakes" you refer to above the rectangular holes that are shown in the attached picture? I blocked these holes, mainly to prevent road dirt and grime from being sucked up into the engine compartment. I considered beforehand whether this would cause overheating of the inverter, but decided that it would not for the following reasons: 1) the inverter is water cooled and the air intake for its radiator is through the front grill vents; 2) during the summer when inverter cooling is more critical, the air coming up through those holes would be hot from the high temperature of the road surface; 3) the holes are designed to accept covers with predrilled plastic rivet fastener holes and appear to be for inspection of the hoses and connections. The above said, I am considering buying a scangauge to confirm the above and appreciate the information you provided on how to program it.
If anyone knows - does monitoring the inverter coolant temp give an approximation to the MG1 and MG2 temperatures? Or do they run separately thermally and need to be monitored separately . Thanks.
