AC Neutral (N) is a pin connector on charging cables for electric vehicles. They are one of five pins on a type 1 connector and one of seven pins on a type 2 connector. It is a standard pin that can be used for single-phase and unbalanced loads, as well as balanced 3-phase loads. A neutral pin helps EV chargers by increasing the compatibility and flexibility of the connector.
How does the AC neutral pin work?
The neutral pin works by completing the circuit back to the source during charging. The AC Neutral pin can work as both neutral for 120V level 1 charging or "AC line 2" for 240V level 2 charging.
