Thank you Srihari Mandava

I appreciate the nice answers.

I understand it.

Are there any disadvantages? I saw the paper. They said that 'Capacity of a transformer' will be overloaded at the specific condition when they used 3-phase voltage for charging.

Thank you for reading my question again.

Sincerely,

Hello,

What Srihari Mandava already mentioned is correct. These are indeed the differences between a single-phase or a three-phase rectifier.

However, for the application of charging an Electric Vehicle (EV) you must also consider the car's specifications. Every EV has its own internal power electronics, which cannot be powered by any charging station. For example, some EVs can be applied directly to a DC power source allowing for fast charging. Additionally, considering a single-phase AC power source is beneficial as this kind of power can already be provided by the grid of your house.

Bottomline: If you are interested in buying an EV, I think it is wise to contact your preferred manufacturer for more information.
