Here is the procedure my dealer recommended for long-term storage of a Porsche EV. The Bulletin he referenced is copied below.
Summary:
Over inflate your tires (3-5psi+) and/or place them on tire saver pads.
Charge car to approximately 50%
Attach level two charging cable and leave plugged in
Deactivate charging timers and do not check on the car with Porsche Connect while away
Lock and make sure your keys are well away from the vehicle
On the 12V battery specifically: contrary to common belief, the unit used to power accessories is not a standard car battery. It is a small lithium-iron-phosphate device, the size of a motorcycle battery. ~2kg (5lbs) vs 15kg for an ICE battery. And it has it's own built-in battery management system and LIN bus communications.
What that means, I'm told, is that the 12V is integrated into the overall battery management infrastructure. And the high voltage battery is designed to keep the 12V charged. It is designed to stay charged if the car is left plugged in while sitting for an extended period of time.
In another thread, a member mentioned having his 12V battery die, having left it at the airport for a period of time. My first EV was a 2018 Jaguar I-Pace. I had to replace the 12V in it. So far no problem with my MY20 Taycan Turbo, despite having left it for weeks not plugged in. In fact, the thing has been bullet proof. Fingers crossed that doesn't curse me!

Advanced Technical Information Bulletin #: 2003
Condition: When parking or storing a Taycan for a prolonged period of time, the recommendations and procedures in the Owner’s Manual and other customer-facing documentation may be incomplete, unclear, or difficult to understand.
Technical Background: As a Battery Electric Vehicle, specific procedures are recommended to ensure vehicle operation and to reduce the aging and wear and tear of the 12-volt and high-voltage batteries.
Service Information: Please review the recommendations given in this letter in addition to existing customer-facing and technical liteture (Owner’s Manual, Workshop Manual, and Technical Information bulletins, for example). The letter on page 3 provides recommendations on Taycan long-term parking or storage, and may be provided to customers where appropriate. If a customer plans to store their vehicle for more than 3 months, it is recommended to discuss additional options for periodic vehicle inspections or service.
The Porsche Taycan is equipped with a 12-volt Lithium-Ion battery which is automatically charged and maintained by the High-Voltage (HV) traction battery and battery electronics. When parking the vehicle for long periods, it is recommended to leave the vehicle connected to suitable AC electric vehicle supply equipment (the Porsche Mobile Charger or Mobile Charger Connect, for example) via the charge port on either the driver's or passenger's side.
Taycan vehicles cannot be charged using the Charge-o-mat Pro maintainer available from Porsche Tequipment.
Instructions for leaving the vehicle parked or in storage for a period of up to 3 months:
1. Charge the main HV “traction” battery to approximately 50% before parking or storage
2. Inflate tires to minimize flat spots during storage: 51 to 58 psi (3.5 to 4.0 bar) at 68 °F (20 °C)
3. Place the vehicle in Park and use the central display to deactivate the electric parking brake
o Block the wheels to prevent the vehicle from rolling
o Settings -> Vehicle -> Parking brake
4. Ensure all Charging Timers are deactivated via the central display
5. Configure and activate the “General charging profile”
o Set the high-voltage battery to charge to 85% to reduce aging and wear and tear of the high-voltage battery
o Select the “Optimize Charging” radio button
o Check the box to activate “General charging profile”
6. Close windows, front and rear lids and doors
7. Switch off the vehicle
8. Connect the vehicle to suitable Level 2 electric vehicle supply equipment (the Porsche Mobile Charger or Mobile Charger Connect, for example)
9. Lock the vehicle using the key remote
10. Store the vehicle key at least 30 feet (10 meters) away from the vehicle
11. Avoid repeated or prolonged use of the Porsche Connect smartphone app. Establishing a connection between the app and the vehicle can lead to a discharged 12-volt battery
12. If possible, ambient temperature for the vehicle should be between approx. 32 and 68 °F (0 - 20 °C) during storage If it is not possible to connect the vehicle to suitable electric vehicle supply equipment
If it is not possible to connect the vehicle to suitable electric vehicle supply equipment, follow the instructions detailed above, with the following exception: 1. Check the high-voltage battery at least every three months and ensure it never falls below 20%; recharge the vehicle if necessary
Summary:
Over inflate your tires (3-5psi+) and/or place them on tire saver pads.
