EVSE

1 phase 240 V
3 phase 415 V

is a three phase load!!

infra needs to be a single point solution

$$W=V\times I$$ $$W=V\cos \varphi$$ $$W=\sqrt{3}\cos \varphi$$

3W -

at 11kV u can have a short circuit current of 12kA to 25 kA

415V its 6 to 10 kA

2511 EV 4Ws , 4094 EV 3 wheelers
each board has 7 outlets,

8 boards 4 wheelers

12 boards for three wheelers

3.3 kV for three
