EV can charge with either AC or DChubby just said why would you want 3phase when it can couple to the DC
AC power is what comes out of the wall sockets
DC power is what the solar panels supply to the solar panel inverter.
AC charging: - Ev wall charger >> car's inbuilt inverter >> EV battery
DC charging: - EV DC charger >> charger direct to battery bypassing the car's inbuilt inverter.
Home charging is limited to AC only. It is not possible to DC charge at home (EV manufacturers do not provide a DC charging option at home).
3 phase 16A-32A per phase.
Tesla and EU EV are all 3phase capable.
Tesla charging rate is 11kWh (230Vx16A x3)
BYD charging rate is 7.3kWh via single phase only (230V x32A x1)
If putting in a circuit might as well go 3phase. Some say put in 32A 3phase , so it can accomodate just about all EV.
If you only put in 3phase 16A and then bought an EV like BYD which only uses 1 of the phase, then it is limited to 230V x16 = 3.7kWh rather than the 7.6kWh charging rate it is capable of (which require 1phase 230V x32A)
Of course you don't actually have to put in 3phase outlets.
A 15A single phase outlet will also be quite good.
A Tesla sitting in the garage for 10hrs a night charging at single phase 15A will add about 180km range. This is more than what people do each day for their daily commuting driving.
