Some Hyundai’s have a 12V battery reset button.

unless resetting the battery also recharges the battery, I don't see why this is relevant to any discussion about the Taycan.

It is not a reset. It is jump starting the 12v battery with the larger battery if the 12v is drained. Then you can start the car and the 12v battery gets recharged.
It is very clever and easy workaround for the 12v dead battery problem that the owner can perform on their own. I hope Porsche engineers follow this forum..

Don’t all the interior switches rely on the 12v battery to function?

why don’t they just have the main traction battery recharge the 12v battery automatically if required?
Seems it would be better to fix the 12v drain issue than put in a button to work around it!

it's a hack, but a good hack - the issue is apparently bringing the big battery online is big deal from a safety and frequency point of view - the manual button "jump me now" has an advantage that you only press it when you need it - so the vehicle can sit for months and it will only get pressed once - keep the 12V "topped" off for an indefinite number of cycles while a vehicle sits unused has it's own implications that need to be considered…

I see this as a glorious hack - it would be best to simply keep the 12V "alive" - but given that seems to be impossible (it's an industry wide problem) this seems to be a reasonable work around and avoid the need to figure out "how/when" and how often to engage the big battery.

They could tie it in to the Start button logic I guess? That must have to start up a bunch of different systems already.

The start button would have to have a separate power system (not difficult) isolated from the 12V system - it could then instruct the traction battery to charge the 12V system, if required.

Much like a start button on a computer, a long press could mean a reset. I have no idea how to implement it, though.
