The Truth About Wireless Charging

Comments 35

  1. Power can be transferred in motion. We have technology that can keep big transfer trucks in the center of the road. To charge batteries with this technology wen you only have to drive into a plug connection in your parking space is stupid, but to send current from the road to the electric motor while driving, even at 25% efficiency would be wonderful, think (up hill – trucks – bypass batteries).

  2. With enough wireless power signal (RF) about where you never needed to make close contact between transmission point and receiver would potentially have some detrimental health effects. Great caution should be taken in the R&D phase to discover such potentials and extreme implications.

  3. Haha u fked up.. 60% efficiency in inductivecharging… Hydrogen is shit Musk said… But if charging is only 60% efficiency… Im gonna fuel my car with hydrogen cheaper and faster!

  4. I applaud using technology to making charging 40% less efficent over older more efficent methods because 6 y/o's think it's cool. As long as a buck can be made who cares ii it's way inefficent.

  5. First off this completely leaves out the topic of phase structure and its affect on DNA. Secondly wind turbines are not clean. I was just in Oregon in an area that burned last year. The natural affect of this should be to fertilize the ground and cause a bloom in ground and below ground life and in most areas this is what has happened. However in areas near wind turbines there is absolutely no below ground life. Small burrowing mammals are nowhere to be found when the should be abundant. I'm not claiming to understand what's going on but this affect is only around wind turbines.

  6. Doubt anyone will ever see this comment, but in regards to inductive charging cars, my dad used to work at Qualcomm, which you can see footage of one of their cars wirelessly charging. One of the big design issues they apparently secretly faced was if an animal were to run between the space of the car charging pad and the pad in the ground, it would be effectively cooked, due to how much power is flowing between those two pieces of metal. I'm no scientist, but in effect, the further away the induction coils are from each other, the more power you need to conductively bridge the gap. Having a thin layer of asphault and then all that air between the bottom of the car and the coils hidden under the road surface isn't ideal, so they tend to pump quite a bit of electricity between them, so if you don't want dead critters, in terms of cars and other vehicles, you'll have to get out of your EV to plug it in or drive onto a large dock where a robotic or hydraulic arm will connect to your car like Jason Torchinsky from Jalopnik envisions.

    Or, if you really want those induction coils, you could slam your car by putting it on air ride suspension, and allow the car to rest right up against the pad so no animals can wriggle underneath, like some sort of Model S that wants to get real low.

  7. real tedious explanation, likely technically correct, the rampant speculation was specious and misleading. Mechanical connectors are prone to fatigue and intermittancy. Better regulators could improve coupling efficiencies. Factually "time-will-tell" if we can get rid of the Trumpers, and depend on scientific developments. Marketing politics be damned.

  8. As I understand it, combustion vehicles generally have an energy efficiency of 20%. Let’s consider the opportunity costs.

    Even if we only went with the 40% efficient charging system, and even if only half the extra grid energy were to come from clean sources, and even if none of the vehicles had a solar panel roof, an inductively charged road network would still yield a net reduction in emissions

    Bonuses:

    – what emissions continued to happen would do so in large, remote, static facilities that can have massive filters, as opposed to gridlock smogs in urban areas with That Guy spewing horrific black fumes

    – less need for road transit of fuel to petrol stations

    – less physical wear & tear on ports

    Drawbacks:

    – what are we going to make all these batteries out of, where are we going to get the raw materials from, what are we going to do with the spent units

    – market pressure to enforce proprietary elements that fragment the market. Like trying to find a lightning charger, but you need to to get home
