Wired an emporium Ev charger turned breaker on and flash and bang came out. Got worried checked voltage and was fine no black smoke.
When the flash came the breaker never tripped tried again and charger came on and was fine.
Was not under load
, so got me worried what in an Ev could cause that.
 
Ya, it was not on my side of the connection though. I have no way of testing the charger since they don’t have a car yet. It blinked correctly and no error code just scared the crap out of me.
 
Sounds to me like a capacitor blew.

It may have opened an internal fuse, or blew a diode before the breaker had a chance to trip.

I would think if anything is wrong such as that an error code would have popped up. Was a really crappy built Ev charger compared to others I have seen.

The "crappy built comment" makes me want to double my bet!! And it seems like a flash and a bang would also cause error code, if nothing else.

It may have blown one side of a full wave rectifier, or maybe there are caps in parallel and only one blew. The computer part of the charger may not be able to detect that. But I would say its hard to tell if the car is going to charge right, or if it will charge as fast as it should, or if an error code will pop up when the charging starts.

The car may just charger slower, and it may be that nobody ever notices.

The controller is only a pass through device, unless it’s a dc fast charger (most are not) it only passes A/C through. The charger itself is built into the EV.

Yes, I assumed a level 2 charger did the conversion, but it looks like it is still AC to the vehicle.

Level 2 is also AC to the car. There is a level 2 dc, but you will only see it in commercial applications, as it takes a 200 amp service by itself. A contactor in the controller just allows the AC to pass to the car if all of the handshake requirements are met by both EV and the controller.
