Blink: bang! (loud noise)

Sat May 14, 2011 7:52 pm

Whenever I start charging the Leaf there's a loud noise (bang!) from the Blink. Is this normal? Does everyone hear it?

I scanned the posts but did not see any reference to such noise, so started wondering if it's an issue with my Blink - I couldn't find any reference in the blink docs either.

That would most likely be the contactor moving to the "close" position inside the Blink, which allows the juice to flow....

Yep, it's definitely the contactor closing. Perfectly normal.

See, you're hanging around a forum that has a lot of geeks about. When we have a box that is going to switch 30 amps we kind of anticipate some monster relay like that will be inside it. That's why there's no mention of it :)
And there goes the first capacity bar! At 24,000 mi on 9/9/2013.
Second bar at 30,500 mi on 2/7/2015.

Schneider reports to duty with loud snap, LuckLeaf beeps back and I know all is well and 80% will be there later. I love this new world! :D :D :D

Thank you everyone - we feel better knowing this clunky sound is 'by design'.
