# How does the charging pile turn the 380V AC into 750V DC?

The output voltage of a mobile phone charger is generally 5V, but do you know how high the battery voltage of an electric vehicles is? Up to 750V!
Charging the battery can only be DC, and the three-phase industrial grid flows 380V AC (different from the 220V AC of the household grid), so how does the charging pile turn the 380V AC into 750V DC?

Hi

There will be AC/DC conversion will takes place  in the first half. AC voltage will be rectified into DC.

DC/DC conversion will be there in the second half. DC voltage  will be converted based on the battery voltage.
