If many people start doing it surely got problem. 1 wall charger 11kW. If condo got 1000 unit and 0.5% (50 people) install then thats 550kW added capacity already, almost 1MW. Electrical system in the whole condo needs to be revised...

Hence I don't recommend people buy EV if their intention is to install wall charger at their condo private parking.

Even new condo (i.e. the Minh) also only have common area EV charging which is like 6 spaces only for the entire condo. And thats is designed and built from the ground up....Old condo retrofit with owner's own wall box surely will have regulation issues or even worse - safety.

The max load is already calculated on worst case that everyone pull full amps on the switchgear continuously. This is not Pakistan where there are blackouts and brownouts as a daily occurrence.

Supply wise on one unit say it’s 63A or up to 63x3 if 3phase means TNB already warranted that you can use anywhere between 0-63A per phase safely.

highest amp of motor is Imax when starting from zero
It is unlikely that ALL 1000x ac motors’ random delay timer match at the same second. Like that better buy jackpot
