NEW BATTERY CHARGING TECHNOLOGY

Qualcom has developed a contactless battery charging technology that it plans to commercialize for electric vehicle battery charging. This could be the answer to that annoying problem of recharging a battery buried inside an engine.

Better make sure there isn't much metal under that engine or near the charging plate. Inductive current from the charger will get them hot. Also that plate will have to be pretty close, my current phone won't charge until it's less than a quarter inch from the charging plate.

Interesting, but I think its "new" from the perspective of solving the difficult task of applying wireless charging to such huge batteries that are found in electric automobiles, and the associated safety issues and view toward regulation, etc.  So I'd say the elsewhere existing wireless tech mentioned above is probably more commensurate with any needs in our hobby.  

Bob seems to be talking about the Qualcomm Halo™ Wireless Electric Vehicle Charging that they're talking about.  Very difficult to imagine this will be cheap enough and scaled to model trains anytime soon.

I suspect some will squawk about the 90% efficiency, that's a pretty big hit to avoid plugging in.

Quick and efficient wireless charging technology

Quick charging with high power WEVC, supporting wireless power transfers at 3.7 kW, 7.4 kW, 11 kW and 22 kW with a single primary base pad and wireless power transfer efficiency of 90%+.

Alan, I was pointing out that this is large scale charging, and it's really not that applicable to our situation.  I think the technology used for cellphone charging is probably closer to what we might be able to use.

I dock "myself" every evening to charge a battery in my lower back for a spinal stim implant.  Now if I held an engine in my arms at the same time do you think I could kill two birds with one stone ?  Lol

I made it train related - just showing the technology is here!  And the distance is probably  1/4 to 1/2 inch so there could be a " park the engine in the new charging facility" on the layout.  Time for a new accessory !!   JP

I spent 45 years in high tech trying to come up with neat ways to solve ongoing problems. When I spot something new, I start thinking how it could be adapted to my current interests and keep the negative aspects to a minimum. For example, when first presented with the idea of a cellphone, the Bell System (now AT&T) said: no way!

According to the link John provided, Qualcomm is using is “resonant magnetic induction“ which is quite a bit different than inductive charging.

it’s just a matter of time before someone miniaturizes the technology so it can be used in things like our trains.
