Well you have 3phase power So that's good. Looks like you have 20 per phase.
You should be able to pull 12-16a per phase, but this depends on your other loads in your house.
One issue you may have is that you have no more space in your breaker box unless you go for single phase charging.
This begs the question, how fast do you want to charge?
3phase @ 16a will get you around 75kmph charging rate (11kW)
1phase @ 32a will get you around 50kmph charging rate (7.2kW)
I have 2 chargers installed in 2 locations, a 32a and that fills me up in ~8hours and a 24a that fills me up in ~11hours. Model X75D

Two things you should get done when the electrician visits, get a Surge Protection Device (SPD) installed and also just for a safety point of view, install circuit breakers.
Oh and that exposed wiring underneath, that shouldn't be exposed like that.
But yeah, the charger should be a easy install. Just think if you want to do solar or a house battery at home in the future as that may influence your choices of if you want maybe just a single phase installed instead on a circuit not connected to the battery.

5 separate power circuits seems over the top. May be able to consolidate some of those and give you some space in the enclosure.
Consider a garage sub board in case you are going to also add solar

5 power circuits is hardly any. My garage has 5! Agree in parramaniacs case a sub-board seems like the right way forward
Actually he has an 80 amp 3 phase main switch so he has 80 amps per phase, don't know what the 20 amp 3 phase circuit breaker is for as it is not marked, but you should have plenty of spare capacity, though it probably wouldn't hurt to do a maximum demand calculation (I could do that for you if you give me enough information), so it comes down to how far you travel each day and how much you are willing to spend to install a charger
The most expensive option is a wall charger ( The Tesla one is probably the cheapest at $780 plus cost of installation), this will give you up to 11KW (75 Km/h of range added)
The next is to use a 32 amp 5 pin tail (Available here - Gen2 Mobile Connector Adaptor (Model3, ModelS/X 'Raven') - EVchargers - EV cables and adaptors ) for the Universal Mobile Charger that comes with the car ($155 plus cost of installing a 32 amp 5 pin Outlet) this will give you $7.4 KW (50 Km/h of range added)
The cheapest option is to use either the 10 amp - 2.3 KW (15 Km/h of range added) or 15 amp -3.6 KW (25 Km/h of range added) tails that come with the UMC, the only extra cost will be installing a 10 of 15 amp outlet in your garage if necessary
Can't be you would trip it every time you used the AC which is on a single phase 32 amp breaker
Yeah, I didn't look too closely at that. 7kW electrical is a beast of a A/C unit though!
In older installations the Main Switch didn't have to be a circuit breaker as well, so the maximum current draw per phase would be limited by the size of the service fuses which are probably 80 amp from what I was able to find
The quoted capacity of an A/C is the cooling/heating capacity, not the electrical draw.
Daikin's biggest single-phase ducted unit, "15.5kW" has an electrical draw of 5kW.
100sqm, and yes correct, dedicated loads to various pieces of equipment, specifically two tesla. 1 for general power 10A, one for a single 15A piece of equipment, and 1 for the backup circuit that does the doors and locks. Actually its more than 5, forgot the aircon(2), pool heat pump (1) and hydronic floor heating (1)
