RF interference question on AV system

[trochetier]

I am considering installing a Level 2 charger on the back wall of my 2 car garage. The back wall is most optimum for charging either car without the cable getting in the way. However, my TV is wall mounted on the other side of the wall and the audio system sits just below it. They cannot moved due to the room design. So my questions are -

1. Do the charging units produce RF? If so, do they come with effective built-in RF shielding?
2. Are there NEC standards for RF shielding of the charging units?
3. Is there a way to determine the possibility of RF interference on my AV system before the charger installation?

No idea, look it up.

If I have an oddball situation like that I do my own research and don't expect others to do it for me. The other issue is that I highly doubt there is data on that. So go ahead, and if it works fine, if not you are screwed. My hunch is that if your proceed with that plan you will be screwed.

Big sheet of copper plate behind the gear in the garage may help?

It will likely induce eddy currents and not likely to help and may make it worse. If you really ground the copper plate, it might help, but I doubt it.

As I think about this, this arrangement is much more likely to induce a huge hum from mutual induction. I would say, that is pretty much a dead certainty.

Would faraday cage be better use of copper? I thought copper shielding even in sheet form had some benefits, but way out of my pay grade. I'd hope the suppliers of the gear can answer the questions tho.
