What is the difference between fast filling and slow filling?

The port of the fast charge is significantly larger than that of the slow charge, and the internal pins are also different, respectively, 9 pinholes of the fast charge and 7 pinholes of the slow charge.

Slow charge: Home 220v16A socket (AC charging pile) → charging line → slow charge port → car charger → power battery.

Fast charge: fast charge pile → charging line → fast charge port → power battery

The fast charge port has 9 pins, which are: negative electrode of DC-DC power supply, positive electrode of DC power supply, ground wire of PE body, negative electrode of low-voltage auxiliary power supply, positive electrode of low-voltage auxiliary power supply, CC1 charging connection confirmation, CC2 charging connection confirmation, S charging communication CAN-H, S-charging communication CAN-L.


Usually the fast charge has 9 pins, while the slow charge has only 7 pins, so the aperture of the fast charge is larger than the aperture of the slow charge, which is the difference between the two. Car charging generally has two apertures of fast charging and slow charging, fast charging is directly charged by DC current, pin charging efficiency is faster, so charging speed is much faster.


Quantity and speed are not the same. The number of fast charging pins is not the same as that of slow charging pins, and the charging speed is also different.

The difference between fast filling and slow filling pins is that the number is not the same, fast filling pins are 9, slow filling pins are 7. Fast charging and slow charging speed is different, the general slow charging of new energy vehicles takes 8 to 10 hours, and fast charging only takes 1 to 2 hours to charge the battery to 80% of the electricity.


Difference: The number of pins is different, the effect is different.

The slow charge port is an AC charging port and has seven pins: CP control connection confirmation cable (feedback charging power), CC charge connection confirmation cable, N AC neutral wire, PE body ground wire, L AC power phase wire, and two alternate phase wires NC1 and NC2.

The fast charging port is a DC charging port. It has 5 pins and is charged by a high-power charger.


Most of the new energy vehicles support fast charging, which is what we call DC fast charging. Generally, there are two ports in the charging port cover plate, fast charging and slow charging, it is obvious that the fast charging port is obviously larger than the slow charging port, and the internal pins are different, respectively, 9 pinholes of fast charging and 7 pinholes of slow charging
