Understand charging and range.
You're not going to get the full rated range on the car, unless you do a lot of slow, stop and go driving.
You don't charge the car to 100%, or discharge to 0%, unless on a road trip.
Don't ever charge to 100% and let the car sit there. Time it so it spends as little time as possible at 100% before you leave.
Things that increase your consumption: rain. Cold. Heater usage. Headwinds. Number of occupants. You should be around 275 Wh/mile consumption normally. But you'll see more than that when weather comes into play.
When supercharging, rate fluctuates based on state of charge you arrived at, then state of charge (charge rate decreases as SOC increases). Usually it's a good idea to leave between 80-85%, depending on next destination.
Use the nav always, Learn to use the energy page for range estimates, and to monitor overall consumption
Use A Better Route Planner to plan long journeys.
Range anxiety will diminish with your knowledge, and quickly.
Set your battery display (displays - energy) to percent, not distance. You'll get a better understanding of how you're using the battery as you drive. You can always easily see range left in the energy graph.
Watts = volts * amps. Kilowatts = 1,000 watts. Your battery stores approximatley 70kW/h. Meaning it can discharge 70 kW for one hour, or 1kW for 70 hours, and so on.
Your charge rate is in kW. So if you want to charge 50% of your battery, you'll need to charge 35 kW/h. If you're charging at 35kW, that'll take you an hour. If you're charging at 70 kW, that'll take 30 minutes. If you're charging at 140 kW, that'll take 15. And so on.
Your mobile charger is limited to 32 A at 240 V or roughly 8 kW.
Your wall charger can do 48A at 240 V or roughly 11.5 kW.
Level 2 Superchargers (the most common) top out at 150 kW. Level 3 top out at 250 kW. But there isn't much of a difference in a long charge between the two, so don't go out of your way to find Level 3.
I post all of the above assuming you no nothing of it. Forgive me if you know some of it, as I didn't when I first got my car. A now good friend explained it all to me and it helped me to understand how to live with the car and really alleviate range anxiety.
You'll enjoy the car as long as it doesn't need service. Don't overthink it!
