Supercharging temperature sensor bug/fault?

[Becareful]

So last night I stopped at a supercharger for 20 mins, it was pissing rain and around 12oC outside.
After setting off I noticed the external temperature reading start to rise, and continue to rise till 25oC, stayed there for about 15 mins and then gradually fell back down to the correct reading.
Is this excess heat from the battery getting to the sensor or perhaps a bug? I’ve never noticed this happen before, but then I use the superchargers pretty infrequently.
Anyone else had this?
Cheers!

What car were you driving? you seem to have options

Model 3 LR, trading it in for a MY soon

I believe the sensor is behind the front bumper, so it could be the battery causing this. Next time I SuperCharge I'll have a look. Certainly not noticed it with rapid chargers.

Just had a look at Teslamate for the last Supercharging session. I don't see the Temp rising while charging - in fact it stays a steady 2C. But about 10 minutes after the charging I can see it climb to 15C. Given this is in the NE of Scotland, then I doubt the local temperature rose that quickly.

Good thought about checking logs.

I just checked the same from a ~25 minute Supercharge last Thursday. Our outside temperature fluctuated by no more than 1C (6-7C) which is entirely consistent with the 35min drive there (pre conditioning) and onward 15 min journey.

Still on 2021.44.6 and 2019 LR with no heat pump if that makes a difference.

I stopped at Scotch Corner Friday lunch time and noticed my outside temp rose to around 18 degrees after setting off back down the A1 before it fell back down to 7degrees

Glad it’s not just me then!
Thanks for looking into your logs!
Do you think this is a sensor placement issue? I felt like as the outside temp was reading falsely high (25 at the time), it was pumping air from outside into the cabin to try and warm it up, which was actually cold. Could of been my imagination tho lol.
I did start to worry when that it wouldn’t stop rising and there might be a fault with the battery causing it to overheat.
Worth reporting for a service visit? I might not bother as expecting to trade in for a Y in a few weeks.

I wouldn't bother if you are trading in. That's bound to complicate the trade-in. Just keep an eye on it.
