was wondering if the battery is fetched drastically while I’m not moving?

This is one of the best bits about driving electric. Whilst you're not moving there's hardly any juice coming out of the battery. It's mainly stuff run from the 12 volt battery (which is then topped up by the big battery). Mainly it's stuff like the AC and heating. On mine that will be the equivalent of 4 miles in an hour. So if you shut those off you're barely using anything at all. However, as I said, it's so small a drain that I wouldn't bother being uncomfortable just to save a few electrons. It ain't worth it.

Another plus is you aren't putting out all those noxious gases whilst standing still.

And lastly, how much does it cost for a full charge?

Mines 43 (ish) kWh. I have Octopus Go which costs 5p per kW for 4 night time hours (mine is 21:30 to 01:30). Works out at around £2.15, but it's rarely a full charge every night as there is always some left in.

You can charge every night if you wish, but you only need what you need for the day/journey plus a bit. It's up to you. You'll get used to your usage pattern and charge when you think necessary. My daughter charges her's almost every night. She has a Leaf 30 and a very long commute. If she forgets to charge for work days she has a struggle to get home. I'm retired, so I make sure that I have enough for tomorrow's journey. If I'm going nowhere (and there's enough for getting about) I don't bother charging. I charge about twice a week.
