Those measurement most likely not so perfect bc a probe is on top of the motor but is giving me some indication what is going there.Summer NY. outside temperature 90 ‘ F. On motor 123’F.Winter car sitting in garage overnight 100% charged temp.almost 60’F open windows I’m assuming interior motor and batteries the same temp.Outside temp.22’F.After few miles driving temp.fall to 29.8 ‘F.and was as low to 26.5’ F.after 30 miles of driving .I just wander what is with 115’ F .outside in Arizona or Negative 40’ F. In Minnesota? IMG_1299.webp IMG_1304.webp IMG_1305.webp IMG_1306.webp The most efficient temperature for EV is in mid-60s degree to mid -70s Fahrenheit .

Can actual motor temperature be retrieved with any of the OBD access apps and dongle combos? I’m sure the MCU must be able to monitor motor temperature as well as battery temperature. Every summer I tell myself I’m going to look into this further, but have not gotten around to it. Maybe this year…

This is one of my complaints about cars in general. Modern ECU’s monitor everything. There is no excuse for this data not being available in any digital dash, maybe not on the main screen, but it could certainly be on a subscreen.

What would you do with the information?

Practically the information on a temperature clock is useless is more like high school experiment I did in 1960 sties and because HAVC system is very complicated on SE better all this temperature sensors work correctly according to their design not like thermostat on ACE cars when they were failing quite often .With so many sensor requirements I wonder if they fail too some day.IMG_1309.webp IMG_1308.webp IMG_1307.webp
 
Granted, you can't change time, but you do something with the information. (I am assuming that you occasionally look at a clock.)
