Internal structure of DC charging pile line of electric vehicle

   When it comes to the internal structure of DC charging pile lines, they are not complicated. Although some of them have more than a dozen internal lines, they actually function nothing more than the transmission of DC power and signals, and the three-phase power processing is all carried out inside the huge charging pile.
 
   The terminals of most DC charging guns on the market are the same, and the DC charging pile lines correspond to these terminals respectively:
 
DC+ The DC power supply is positive
 
DC- The DC power supply is negative
 
S+, charging communication CAN-H
 
S-, charging communication can-L
 
A+, low voltage control power supply is positive
 
A-, low voltage control power supply negative
 
PE: ground
