Best picture I have seen that the charger lives in the lump behind the rear seats.. looks like a bit of component relocation could result in a flat cargo floor. Best place to place the filters in the AC line.

My LEAF was repaired last week, and I am now enjoying being able to charge during the day without setting off buzzing in various electronics. I recommend Nissan Sunnyvale for those in the SF Bay Area with this issue...

Absolutely! Considering how quiet it is to drive around, the electrical noise problem was even more irritating...

hmm inverters and converters (charger todays wording) not talking to each other. lets go back in time to early 70s nasa,learjet,hansa,gulfstream,IAI all had the same problem waves all of them(sine, radio) ,magnetics,speakers.these and transitors ring a bell!! I remember my first cell phone (cost $6000.00)would buzz when I would pass a RADIO station and somebody figured it out hence a NEW product it was called a RF FILTER. as we all know todays bright people will figure this out.and all parts will play nice!! we even get FREE cell phones but bandwidth cost alot.Ive never seen a bandwidth have you.Its friday and had a bad week so here is some humor for the day!!!

Bumping an old thread up here, VIN 2193 and I definitely have this issue. I used to live with a detached garage far from the house on its own 100A sub panel to which I never had any issues noticing any noise. I have since moved to a smaller house with a carport right near the living area. The house was built in 1971 with aluminum wiring (which I have been going through with some new wiring methods to make safe) and I had the original 100A panel upgraded to a brand new 200A panel by a professional electrician as the original panel was sketchy at best.

I'm charging using an open EVSE I built. The circuit I installed myself, it consists of all of 20 ft of 12/2 romex going from the new panel on a 20A breaker pair straight to a NEMA twist lock plug inside my storage room. The open EVSE plugs in to this and goes to the car, it doesn't get much more straight forward than that. Inside the house I notice the noise mainly on LED lights. My kitchen is lit by eight GU10 style 120v LED bulbs spread across the area of the kitchen so the sound in there is particularly annoying.

I'll get the car in to the dealer and see if they can contact the person listed here. Sad they don't have a TSB for this, but I suppose replacing chargers is not a cost effective strategy.

I'm VIN 2062 and had this issue and no problem with getting my local LEAF tech. to replace the charger. I'm not sure if they are still verifying but he did come out to the house to listen to the noise (Even brought a LEAF and offered to swap them if I wanted but I preferred to drive my LEAF while we waited for final approval and the part to arrive.)

If they do want to verify it it might be wise to have the Panasonic EVSE handy so they can verify the issue with that and don't get distracted by the OpenEVSE. Let us know how it goes, hopefully by now it is very straightforward and I'm sure they can identify if your charger is pre-noise filter fix.

Thanks for this thread. I think I have this same issue. The buzzing is bothering me, but my wife can't hear it and sleeps just fine. I can track the whole path of the wire from the circuit box to the vehicle along my walls and ceiling listening to the buzzing. And devices like electric clock radios are buzzing too. And if you listen right at the breaker box it kind of chirps gently while the charging is happening.

I've got a 2013, and have only had it for about a month now, so I wasn't sure if I had a problem with my house wiring or the vehicle. I've tried swapping out the breaker as well as plugging other devices in, but those make no noise. I'm charging through a Juicebox, but I doubt that's inserting any sort of noise. Has anybody heard of a 2013 with this issue? I would have expected nissan to have fixed this for 2013 model.

I guess what I need is a second car to plug in and see if it charges just fine. Anybody care to come to south San Jose near Almaden and 85 for a free charge and a sixpack of beer? :)

My understanding was that the on-board chargers on the early 2011's didn't have a enough noise filtering, which caused some LEAF owners to experience the line noise, but this was corrected in the later 2011's (added more noise filtering to the charger). I just had my 2011 charger replaced to fix this problem. It was a slow process to get Nissan to fix the problem but they eventually did. If your 2013 is having a problem, it could be that you have a defective charger, but I don't think it's because of a lack on noise filtering in the design of that charger unless they reintroduced the problem in the newer chargers. Let's hope they didn't.

From what I understand, the EVSEs are unlikely to be the problem. Your approach of getting a different car to plug into your Juicebox is probably going to be your best bet at initially troubleshooting the problem. It doesn't necessarily have to be a LEAF. In fact, it might not be a bad idea to try out a non-LEAF EV or PZEV. I used my neighbor's Volt to troubleshoot my problem. My LEAF would cause my solar (string) inverters to buzz loudly. When I plugged his Volt into my EVSE, my solar inverters did not buzz. I then took my LEAF and plugged it into the EVSE at his house, which also had a solar string inverter, and my LEAF caused his inverter to buzz! You would think that would have been an open-and-shut case when getting Nissan to fix the problem, but I still had to go through a fair amount of stonewalling before Nissan agreed to fix it.

Unfortunately I don't live close enough to help you troubleshoot the problem, but hopefully someone in the area can help out.

Hope this helps. Good luck!

The relays in my Blink make a fair amount of humming but I don't seem to be able to hear it anywhere else. Definitely see if you can reproduce the issue using the Panasonic EVSE that came with the car.
