This is about the preferred way to manually stop charging before a programmed termination by Leaf timer or 100% SOC.
The power to the EVSE can be shut off, or the J1772 plug can be removed from the Leaf receptacle.
When the J1772 latch release button is pressed this action is signaled to the Leaf which responds with audible beeps but does not terminate charging until the J1772 plug is completely pulled out. The question is, where and how is the current path broken? Is it by mechanical contacts of a relay, by a semiconductor inside the charger, or simply by separation of the J1772 plug contacts?
Does anyone here know?
(the issue of concern is arcing at the break point)
