Talk:Inductive charging

message: "conductive charging generally charges too slowly and generates too much heat for most portable electronics"
wrong. an upcoming Palm smartphone will use it, so its feasible.  —Preceding unsigned comment added by 134.36.92.18 (talk) 00:12, 21 January 2009 (UTC)

message: I found this article to be biased in favor of this kind of technology. There is no discussion at all, in the "advantage and disadvantages" section, of any possible disadvantages, including, perhaps most importantly, the inefficiencies involved in inductive charging. At the very least something needs to be said about that.  —Preceding unsigned comment added by Rgheck (talk • contribs) 00:43, 11 October 2009 (UTC)

replies: text: More than resolved, at least if this was considered to be in favor of wireless charging, I would say. Considering that the lack of de-facto standard is included. The Qi page lists some major phone makers (well, some of them have a bit wider portfolio, I believe), but in addition to those, for example Panasonic, Philips, Energizer, Belkin and Verizon Wireless are behind the standard... No moving or breakable parts when connecting... And lower efficiency is basically listed twice. The references in 'more costly' do not mention anything about the actual cost (well, I guess the coils would by default increase the cost, but is this a significant amount when compared to a 'normal' charger?)?  — Preceding unsigned comment added by Ojisama (talk • contribs) 11:00, 15 September 2012 (UTC)

message: I added a reference to powermat in the main page, the company plans to commercialize wireless charging. the link is below to their website.
*I’m a Powermat Employee, but I wanted to weigh in on this because some of our recent applications might fit in the “Examples” section. 
Powermat unveils it's line of wireless charging products at CES 2009. Powermat provides wireless charging by means of magnetic induction through a two part system which requires a receiver and mat.http://www.i4u.com/article22599.html--Powermatassistant (talk) 21:06, 25 June 2010 (UTC)

message: I added a green section to this topic. The idea of inductive charging vs disposable batteries is a green issue. —Preceding unsigned comment added by Bh36njit  (talk • contribs) 05:28, 30 November 2009 
: No, rechargeable battery vs. disposable battery is a green issue. How the battery is recharged is a less important environmental issue that's part of, and implied by, efficiency. It looks like someone (correctly) removed any "Green Section" from the article. -- Skierpage (talk) 02:34, 24 May 2010 (UTC)
replies: text: Actually, Inductive charging itself can be a green issue. Many products the employ the use of inductive charging also have smart technology within it that allows the unit to stop supplying power to a device once it is fully charged. This prevents overcharging of the battery, thus prolonging the life of the battery in the device. With one ac adapter you can charge up to 3 to 4 devices at a given time reducing the need for a power strip. This will help reduce the amount of electicity that is being used which is also a green issue.--Powermatassistant (talk) 16:53, 7 July 2010 (UTC)

text: That's an entirely unbalanced opinion! Appliances which are entirely switched off instead of in standby do not draw any power. Old transformer units (aka wall warts) do continue to draw a tiny amount of current but those are quickly being replaced by much more efficient switched mode units so this is a none issue. Wireless charging is less efficient than charging with a cord and therefore less green - there's no 'ifs' or 'buts', wireless charging is a backwards step in 'green' terms not a forward one. 82.17.93.186 (talk) 10:26, 21 August 2013 (UTC)
thread_title:  Green Section 

message: First, to the "green" guy above. It will be great when we don't have all these dead batteries lying around. However, if the guy above is right and it take much longer to charge "green" inductive batteries, then it will take more electrical power which means more power companies producing all the more greenhouse gases or nuclear winter gases, I forget which one we are harping on at the moment.
Second, anybody here remember a guy named Tesla? He already had wireless electrical current perfected back in the 20's.  —Preceding unsigned comment added by Alabamaxslim (talk • contribs) 07:06, 27 December 2009 (UTC)

thread_title:  Inductive charging and V-Poles 

message: I used to come to Wikipedia to get an unbiased opinion of various subject matters and, as of late, all I've been getting is marketing. It seems like companies that sell these technologies are dictating what's on these articles. That's unacceptable and really shows how little shame these companies have.
The sources cited here are also not very helpful.
For example under disadvantages the first citation is a Howstuff works article about how inductive charging works. This article is supposed to be the article that attempts to explain how the science works and cite research backing its claims. For instance what independent studies have been done establishing that inductive studies are less efficient and by how much. Were two similar 1000mAH batteries simultaneously charged by both methods and did anyone time to see how long it took each to become fully charged? Who conducted this research? The second citation is to some useless patent that doesn't give any useful information either.
Then the article attempts to downplay the alleged disadvantages, almost like an advertisement would, by saying "Newer approaches reduce transfer losses through the use of ultra thin coils, higher frequencies, and optimized drive electronics. This results in more efficient and compact chargers and receivers, facilitating their integration into mobile devices or batteries with minimal changes required."
This whole thing reads like marketing. The citations aren't very helpful either with no quantifiable numbers resulting from independent studies. The fourth citation says "The efficiency of electric power transmission is higher than 70%, including the peripheral circuit, according to the company." This is not a valid citation. Independent studies with a stated control group, as a benchmark, and quantifiable numbers are necessary.
I'm sorry to say but this is not science but marketing. If I wanted marketing I can always go to the manufacturer's website. Why has Wikipedia essentially turned into a marketing platform for companies to market their products. I'm seeing it more and more and it infuriates me that this is acceptable. and now you have ruthless Powermat employees coming over here to look for an advertising opportunity. Don't these companies have no shame. Their advertisements should be removed. — Preceding unsigned comment added by 172.248.197.0 (talk) 18:04, 27 May 2015 (UTC)

message: I noticed there haven't been any discussions about the reverse wireless charging, a feature offered by some Huawei and Samsung devices. The article would not be encyclopedic to not mention this new implementation of the inductive charging technology.

thread_title:  Section on Reverse Wireless Charging needed. 

message: There is some discussion on how inductive charging may impact battery life (in real world applications like phone charging):
The issue is that when the iPhone is being charged using a cable, the phone is being powered by the cord (there is some load on the battery, but it's minimal), but when using wireless charging, the battery is what's powering the iPhone, with the wireless charger only being used to top up the battery. This means that by switching from a cable to a wireless charger, my battery isn't getting a break, and in turn, this is making me go through recharge cycles at an even faster rate. Source
I doubt this, becaus you can't simultaneously charge and discharg your battery at the same time. The current goes either in our out of the battery. Still, there may be and issue of charging the battery with constant "small bumps" instead of a constant current. 
Can someone with some technical understanding look into this and check with other sources if this is an issue?

thread_title:  Article looks messy 

message: At least Primove had more omnibus projects, at least up to 200kW, which at least did it to type approval/ Roadworthiness and an evaluation project.
They also had some project for trams, where the development initially came from.
One link to information on their site is https://bombardier.com/en/media/news/bombardiers-primove-technology-enters-service-scandinavias-first-inductively-charged-bus .
I never added something to a complex article here and hesitate to mess it up.
Also I was working for them in the past and do not want to write something biased.
Would be great if someone would add it and I am happy to support based on information, which is available in public (I have to be careful, because for sure I know more than what got published).

thread_title:  At least Primove has/ had more projects 

message: I added a new section header that reads "Safety" in the article. I believe that this is a valuable addition because with advances in technologies we must be aware of the dangers that stronger inductive charging coils can cause with the electrical magnetic fields that are emitted. I included this to what we are headed to in the future but, to also see some possible side effects as well.
I also read the article and added small grammatical error fixations and revision in one sentence. The sentence in question read "Inductive charging is so named because it transfers energy through inductive coupling". I first read this and was unclear on the "so named" and changed it to "named so". I believe both sentences are correct, but this made for a more clear and understandable sentence. — Preceding unsigned comment added by Nhutch2001 (talk • contribs) 03:41, 7 February 2022 (UTC)
