hong kong's Volt is 220V or 380V, Volt can't not maximum, my example 220V 32A, but volts are about 208-215 ~ 6.6Kw.

11kW鎗嘅电源系220V*16A*3P
架车净系食到单箱AC的话咪就得11kW嘅三分一

三相又得7kW的话咁好可能系向排得10A嘅掣度攞电

要看每架电车AC 上限kw, 老婆公司三相充电盒可选20 或32A , 老婆同事atto2 只能食尽11kw, 而我smart#5 可食22kw.

I dont understand what you are talking about.
What is "can't not maximum"?
Anyway that havent solved my question of why only half "尤其当架车嘅OBC得单相6.6kW充电速度就祇有3.3kW"?

Yes, obviously that commercial building limited output to 10A to enhance efficiency which I like. So I was giving you a real life example of not a must to get 11kW with 3P.

You said if only 1-phase then our intake is much lowered (in fact by sq rt 3 not 1/3 assuming near ideal pf).
But that havent solved my question of why only half "尤其当架车嘅OBC得单相6.6kW充电速度就祇有3.3kW"?
He said he has 6.6kW 1p. Why would the car suddenly drop to 3.3 when he can take 6.6?
Where did you calculate the 3.3?
