So as of now, I am declaring the ScanGauge project dead. I have not heard form James in 2.5 months. This thread will deal with extended PID that we were able to find in regards to temperature. For some of the newer members, check out this thread that talks about PIDS related to battery capacity and energy: https://www.insideevsforum.com/community/index.php?threads/scangauge-ii-extended-pids-capacity-and-specific-energy.2633/ There 5 temperature readings that will be discuss: DCT – Temp of DC-DC converter. Last in the electric powertrain coolant system HBT – Temp of lithium traction battery*** AIV – Temp of air inside cabin AOV – Outside air temp FWT – Temp of coolant in engine (this will be discussed separately) ***In regards to HBT, the value that I am get is a large number i.e. 120F. I am 99.97% sure that dividing the value by 2 gives me an accurate temp of the battery. In this case it would be 60F. Either the PID is missing the divisor, or it is picking up temp readings from 2 of the sensors. I know there are at least 3 temp sensors for the battery pack and possibly more. I have tried a few times to have James examine this PID more closely but have not heard back. The next few posts are observations from several different days. Spoiler Alert: the hybrid battery pack temperature is very slow to change (at least in cooler weather) regardless of whether it is sitting, charging or during a drive.
