The main difference between the 7 and 5 holes of the AC charging gun is the applicable charging standard and the charging function that can be provided.
The 7-hole AC charging gun usually follows the three-phase AC charging interface standard in the IEC 62196 standard, which can support three-phase AC input, suitable for some high-power charging scenarios, and can provide faster charging speed. These seven holes include L1, L2, L3 (three-phase phase line), N (neutral line), PE (ground line), CP (control guidance), and PP (which may be used for other controls or signal transmission).
The 5-hole AC charging gun generally follows the single-phase AC charging interface standard in IEC 62196. It only supports single-phase AC input, and is suitable for ordinary families or small charging scenarios, with a relatively slow charging speed. These five holes include L (phase line), N (neutral line), PE (ground line), CP (control guidance), and PP (which may be used for other controls or signal transmission).
In general, the 7-hole AC charging gun has advantages in charging power and speed, and is suitable for occasions with high charging speed requirements; The 5-hole AC charging gun is more suitable for ordinary families or small charging needs. In practical applications, the appropriate charging gun needs to be selected according to the charging requirements of electric vehicles and the configuration of charging facilities.
