Wireless charge pad failure (possible reasons/fix attempts)

I think I know why the wireless pad doesn't work. I had always suspected it was due to the "proximity" of wireless device and how much power that device demands. I say this, because I air pods always work. [Edit: Airpods do not always work]

So here's a video of an experiment.

I think his idea would work just fine, cut out the plastic and leave just the rubber pad in place. I might give this a shot with mine to see. I could see a thinner piece of plastic, but if the rubber pad is going to cover it, seems like you don't want anything else in there.

I wonder if a person just cut out a small oval part out of the plastic if that might work? Not remove it completely and still allow the rubber to stay separated from the coils and not overheat? That would allow the space between the rubber and the coils to avoid overheating and allow the charge to penetrate? Thanks for posting this, this is very interesting.

Well, that's what I was thinking at first and I say that in the video... but I tried and it didn't work. The charger is just so weak that the proximity is not close enough. Here is my attempted hack to try just what you were thinking. Too bad too. I think my next try will be to use small washers to act as standoffs on the screws of QI Coils to get them closer.

Do the coils actually get hot? I’m thinking maybe the rubber pad may be all you need to separate the phone from the coils, since rubber just like plastic does not conduct electricity? Is it not more of a magnetic current than actual coils that are shorted and get hot? I am definitely not an electrician, not even close. I’m just wondering if the rubber sitting on the coils would actually get hot? I’m thinking if they actually got hot, wouldn’t the plastic barrier get hot too?

It doesn’t work well with new iphones for a couple reasons.
1: The cameras stick out too far and don’t let the phones lie flat.
2: The mag safe magnets embedded in the phone interfere with it
3: cases are too thick to allow a decent connection
I agree about the camera's protruding, that is about the needed distance elimination to secure a working condition. If the phone was flat, it probably would work. But still.... Ford made it work ok.

What you should also be monitoring is the input voltage into the device. Those design parameters could be part of the failures too. If the input voltage should be 13.7 to work properly and you only have input voltage of 12.5 at the device that would also explain why the charging is intermittent. Put a meter on there and lets see what is being supplied to it.

Honda needs to scrap their supplier for this charger. They probably have a gazillion of them stockpiled. The 2024 Ridgeline will have 6 charging pads scattered throughout the vehicle as a way to clear inventory and call it a Special Edition wireless charger.

If the Odyssey's works... I wonder if the internals are the same. Honda maybe wouldn't produce more than one circuit board, charging core. The photo looks like the same type of module. Just mounted differently and I wonder if it is purely proximity within the internal mounting. If I had resources to swap vehicles charging pads, I would... they are simple to snap/pry out.

It’s a shame but it doesn’t really work with my iPhone 14. My wife’s Audi SUV’s charger works perfectly and that car also has wireless CarPlay.
Honda should come up with a working pad and retrofit it. I feel I paid for an option that ain’t there.
As to CarPlay, my concern with wired CarPlay is that I don’t want to charge the phone constantly (and it would look cleaner without the cable)

Verdict: It works now, but pretty sensitive to position. If it moves off-center it stops. The phone does better if it is oriented as the top pointed toward the passenger side. I had it charging for about an hour and it stayed, but it was a very slow charge. Honda should be embarrassed, and I firmly believe they owe all of us $500 or a replacement. I'll revisit this some other time.

Here is my .75mm thick sheet that I put over the coils and then double sided taped the rubber pad back in place. Haven't driven it anywhere to know if it helped at all or not, but I suspect I will be in the same boat as Nervey. I can usually get it to charge with an angled positioning before, hoping this helps it charge a little faster than it had.



I really think it may be worth it to get a nice fast charger, disassemble it and put the guts in this one. The only thing I am not sure is what kind of power draw this thing has to know if it can handle what the fast charger would need. I definitely think this would work relatively well.
 
#35 ·
Has anyone tried checking the circuit to see how much power it's actually drawing? I wonder if there might be a relatively simple mod that would allow the coils to draw a bit more power might solve the issue. I don't have a RL with one of these or I might be tempted to play around with it. I suspect that swapping it with an off the shelf charger might end up being the easiest thing though.

I never had issues with mine. Huh. In the very beginning that's why I thought it was odd that people complained about the charger, I remember the phone I had at the time I bought the truck didn't do wireless charging, but my AirPods did, so I was one of those folks saying, "Hey mine works." But even though the charger latches to my iPhone 14 now it's still not charging much at all.

[The Airpods are hit or miss, and subsequent tries have not produced successful charging]

You would need a higher input voltage and then you will need to know the input range the module can take before frying itself. As I said before. Measure the input voltage to it and see if the truck isn't supplying enough to make it work correctly. There's a good possibility of that.

Tonight driving to my son's game was the first chance I had to test my revamped one out. I will definitely agree that you have to be mindful of it moving, but it added 3% to the charge in a 10 minute drive. It only shifted enough to stop charging once in that time. Not the fastest, but seems to be a bit faster than it had when I got it to work before.

This forum is awesome!

Seems like just adding a simple MagSafe charger for iPhones would be a nice solution. Remove guts , Drill small hole for usb then glue mag safe charger to pad. Convert 7 pin connector to usb port and presto. My current set up in the center console but this would be cleaner .

Silly question but can I just pop off the wireless charger or do I need to take out the center console?
