I got a "Battery too cold, plug in to warm" message while
The software update I''m mentioning changed how the software handled the battery pack temperature sensors. I believe there are multiple sensors in some or all of the sections of the battery, so the update reworked the software so the battery could function normally even if one of the sensors died. It just relies on the remaining working sensors.

NTC Temperature Sensors for Battery Applications
Battery temperature is a key indicator of 3 major parameters of a battery pack: Safety, Performance, and Lifespan.

The pack must be taken out of use, but a safety hazard will likely have been avoided. For comparison, if only neighboring cell 3 had a temperature sensor, the BMS would not detect a similar failure until 5 minutes later (figure 4). If the temperature sensor was two cells away on cell 6, the delay would increase to over 10 minutes.

View more6 FAQs about [Where to put the temperature sensor of the battery pack]
Where should a battery sensor be placed?
We usually put a few sensors right near the battery tab, as close as possible to where it exits the pack. That is at least the most reliable place that doesn't suffer from much lag / insulation. For more accurate temperature we run a complicated VI power curve, comparisons to all cells in the pack, 2-4 pack temperatures etc.
Where should temperature sensors be located?
Even using a FLIR and deliberately running packs hot, it is evident that temperature sensing is very unpredictable and suffers terrible lag, for the reasons you point out. We usually put a few sensors right near the battery tab, as close as possible to where it exits the pack.
How to test battery temperature sensor?
1.Battery temperature sensor is snapped into battery tray, below driver's side battery. Disconnect wiring harness at battery temperature sensor. 2.Using ohmmeter, check resistance between electrical terminals on battery temperature sensor. Resistance should be 9000-11,000 ohms at 75-80°F (25-27°C).
How does a battery temperature sensor work?
Battery temperature sensor delivers input signal to Powertrain Control Module (PCM) to indicate the battery temperature. PCM uses battery temperature input to modify rate of output from the charging system. Battery temperature sensor is snapped into battery tray below driver's side battery.
How do you put a BTS/RTS on a battery?
With multiple strings of batteries it becomes a bit problematic, so would get rid of multi strings, and then place BTS under one battery center of the bank, half way down the side, under rigid foam on the single string of batteries. Also, would place ALL BTS/RTSes on the same battery, under the same foam sheet -- very easy.
Can you put a battery on a side?
If you are forced to use it on a side, add a layer of thermal insulation like fiberglass or foam to keep the ambient temps from interfering. ONLY on the side of one battery in the center of the bank, and only under a rigid foam sheet one, or more inches thick.
