BMW's wireless car charging pad arrives this summer
The notion of wirelessly charging your car is no longer a distant prospect... if you have the right ride. Car has heard that BMW will start producing an inductive charging pad for the 530e plug-in hybrid in July, with a release by the end of the summer. Autoblog has confirmed that the pad will be available in the US in addition to the expected European release. It's not certain how much the pad will cost, but one thing's for sure: you can't just walk into the dealership and buy one.
Volkswagen announces e-Golf Touch with gesture controls
Not nearly as exciting as the electric BUDD-e microbus the company introduced a new version of it's electric compact, the e-Golf Touch at CES. Odd that it's called the Touch because the feature that makes it different from the regular e-Golf is gestures. Maybe e-Golf Swipe didn't play well with focus groups. Regardless, the car comes with a 9.2-inch configurable home screen and wireless charging for everyone in the car.
With Qi wireless charging, you'll soon be able to charge your device from a short distance
It's becoming more and more common to find mobile devices with wireless charging capability, either as a built-in feature or integrated into third-party cases. Progress has been somewhat hampered, however, by the fact that no universally adopted standard is available. Of the three major groups trying to corner the market, Qi -- a standard created by the Wireless Power Consortium (WPC) -- has arguably been the most successful at courting manufacturers and carriers (over 200 have signed up so far). The problem is, its abilities have been limited because it only uses a method called inductive charging; in other words, you can power up your smartphone as long as it's sitting on a charging pad. Wireless, sure, but it's still only marginally more convenient than simply plugging the handset in. Fortunately, Qi's adding some crucial functionality later this year that will allow you to charge your device from nearly two inches away.
Apple reportedly testing inductive, solar and motion charging for its unannounced smartwatch
We've heard that when Apple reveals its first smartwatch product, there's going to be a heavy focus on health and fitness, but there might also be a way to charge the wearable without plugging it in, according to a report from The New York Times. Inductive charging came in a wave of smartphones last year, including Google's Nexus 4 and Nokia's Lumia 920 range, although we don't often see it in anything smaller than a phone (or camera) form factor. Apple, however, is looking into cramming the same technology into its iWatch, or whatever it eventually calls its debut wearable. It works like this: Electromagnetic fields are generated from a charging base, which are then picked up by metal coils and transformed into for-real electricity that charges your device. The Cupertino company is experimenting with other new charging methods too, although these are apparently years away from consumer products. Sources close to the matter also mentioned the inclusion of a solar layer beneath the device's display, while the company has also looked into kinetically charging its wearables -- something that is already used in many modern (non-smart) timepieces.
Google debuts new wireless charging pad with support for Nexus 5 and 7
Last year, Google unveiled a new wireless charging pad alongside the Nexus 4 and Nexus 10, and the company has taken advantage of 2013 to come up with another one. This new charging pad has been announced in tandem with the Nexus 5, and will include support for it and the Nexus 7. It's supposed to go on sale in the Play Store today, though pricing is still an unknown. So what's different this time around? The new pad, which should work with any device that offers Qi compatibility, has been completely redesigned (it's shaped like a square instead of a hockey puck) and now features magnets that will make it easier for devices to stick on it -- provided those phones and tablets in question have magnets built in as well. We'll have more information about the chargers as we get it, so stay tuned! Nicole Lee contributed to this post.
TDK's Wireless Charging Cube pumps out the jams, juices your Qi devices and resists water (video)
Although TDK mentioned its Wireless Charging Cube at IFA with the rest of its latest portable audio wares, it wasn't until today that we got a look at the speaker. The six by six by six-inch (yes, you read that right) unit features the same retro, black and gold aesthetic as TDKs other Bluetooth 2.1 + EDR speakers, but it's notably housing a Qi-compatible inductive charging base at the top (just like JBL's Lumia-styled Power Up speakers). Along with being splash-resistant enough to stay safely within range of your sink, an internal rechargeable battery will net you roughly six to eight hours of untethered play time. We had a very brief ears-on with this $400 unit, so join us past the break for more details and our initial impressions.%Gallery-166207%
LaunchPort releasing AP.3 sleeve for juicing your new iPad the inductive way
LaunchPort is finally releasing a sleeve for the new iPad, which makes it compatible with the company's inductive charging gear. It goes on sale in September for a hefty $149, and of course, you'll also need at least one $199 tabletop or wall mount to connect it to. The sleeve also works with the iPad 2, and if you're thinking about getting one, be quick -- it's only a matter of time before resonance charging renders inductive juicing a little passé.
TDK introduces new wireless Boombox and two new weatherproof speakers
TDK's Boombox rocked minds and windows alike with its modern take on a retro classic. Buoyed by its success, the cassette-maker of old is back with new audio hardware at IFA. Three devices, again on the speaker front. First up is the Boombox Wireless, which is a similar, but updated, design from the original and features not only streaming sans cables via Bluetooth, a rechargeable battery, too. If you don't want to cut the cord completely, there's a 3.5mm aux input, USB slot for charging plus an FM radio and headphone output. Next up is the Wireless Weatherproof Speaker, which despite being described as "rugged" and boasting an IP 64 weather compliant design, looks like any regular device. It, too, has Bluetooth streaming and built-in battery, along with 3.5mm input and built-in microphone. If these two were all looking a little bit oblong, then the curious Wireless Charging Cube might be for you. Yep, it's Bluetooth streaming again, but also plonk your Qi induction compatible device on top, and it'll juice that while you jam (there's a non wireless charging / charger version also.) How much do these slabs of sound cost? The Boombox is $399, the Wireless Weatherproof is $250 while the Wireless Charging Cube is $399. Not a peep on availability at this time, we'll connect you up though, once we get it.
LaunchPort announces inductive charging system for iPad
We've all wished for cable-free charging of our iPads at one point or another, and now a new inductive charging system called the LaunchPort System is coming soon to give you a way to hold and charge your iPad without hooking up cables. The AP.3 Sleeve fits on your new iPad like any other sleeve, cradling your iPad and providing protection. But it also comes with a powerful magnet built in to attach it to a wall station or base station (sold separately for $199 each) where it immediately begins charging the iPad. That magnet can also grip a metal surface like a refrigerator or workbench, although it won't be receiving a charge in that situation. When it's off one of the mounts, the AP.3 Sleeve features hand grips on each side that make it easy to hold. The magnetic mounting/charging system allows rotation of the iPad a full 360 degrees. There are also AP.2 Sleeves available for the iPad 2 -- one comes with security features and a Square card reader holder built in for retail point-of-sale use. TUAW will be reviewing the LaunchPort AP.3 Sleeve and mounts in the near future. In the meanwhile, check out the system and revel in the lack of cables.
Microsoft earns patent for claimed wireless charging improvement, pad with info screen
Device makers are bent on bringing us inductive charging, and Redmond has joined the fray with a recently allotted patent that describes all kinds of tech that could make it work better. For the charging itself, a trick is proposed that's similar to one we've seen before -- careful matching of the resonant frequency of charger and device. That would amplify efficiency and allow more than one device to be charged at a time. To make it easier to use, a pressure sensor could detect if a device was on the pad, with different parts of the pad allocated for smartphones or tablets, for instance. The patent also proposes a display placed opposite the charger to give it another use when it's not juicing, which would be determined by a gyro to sense which side was facing up. Of course, a lot of patents are whimsical things, which never amount to anything -- but judging by the detail in this one, Microsoft may have something more concrete in mind.
Japanese group transmits electricity through 4-inch concrete block, could power cars on roads
The decision to invest in an electric vehicle would be much easier to justify if the car in question offered unlimited range. That appears to be the concept behind a Toyohashi University research group's wireless power prototype, which can successfully transmit electricity through a 10 centimeter-thick concrete block. During a demonstration in Yokohama, Japan, the team sent between 50 and 60 watts of power through a pair of concrete blocks to two tires, which then juiced up a light bulb (you can see the rig just above). The project is called EVER (Electric Vehicle on Electrified Roadway), and could someday be used to keep cars moving along a highway without any need to pull over for a recharge, thanks to a constant stream of electricity coming from below the road. There are some serious obstacles to overcome before EVER can get some wheels turning -- namely, a need to pump nearly 100 times the current maximum load through concrete that's twice as thick as what they've managed today, not to mention improving undisclosed efficiency levels -- but the group reportedly said that it's up to the task, making us fairly optimistic that such a solution could one day get us from A to B without petrol. Until then, you'll probably want to plan out a pit stop or two before you leave the garage.
Intel shows off wireless keyboard that re-juices via resonant charging (video)
Imagine this: Intel hosts an event with dozens of Ultrabooks arranged on tables. All the tech writers in attendance rush past them, and instead swarm around... a keyboard. That was the scene at one of Intel's Computex press events today, where the company demoed an interesting use of inductive resonant charging using a concept all-in-one PC and wireless keyboard. As you'll see in our walk-through video, the 'board starts charging as soon as you press it against the base of the PC. Now, we know, we know: wireless charging is hardly new, but what impressed us here was that the presenters didn't even need to rest the keyboard flat on top of something else; even making contact from the side was enough. According to an Intel rep staffing the event, the company has considered porting this technology over to other accessories. No word on how soon you'll be able to try any of this at home, but for now we've got photos below, along with that video we mentioned. Update: The wireless charging technology in use here is resonant, not inductive charging.
Scientists tweak wireless power transfer, Tesla nods happily in his grave
Wireless charging may be all the rage these days, but actually beaming electricity -- as sketched above by the man Tesla himself -- still has some snags. North Carolina State U researchers have found a way to possibly vanquish the biggest problem: the difficulty of exactly matching resonant frequencies to amplify current. If external factors like temperature change the tuning of a transmitter even slightly then power drops will occur, but circuitry developed by the NC State scientists would allow receivers to detect these changes and automatically re-tune themselves to match. This could make for more potent car and device charging in the future and, if they stretch the distances a bit, maybe we'll finally get the wire-free utopia Nikola dreamed up 120 years ago.
Duracell Powermat WiCC could bring wireless charging to any smartphone, we go hands-on (video)
Powermat may have a bright future, but the company's products to date have been expensive, slightly clunky and a generally imperfect solution for bringing wireless power to mobile devices. That could all change with WiCC. The Wireless Charging Card (WiCC) is an IEEE Power Matters Alliance (PMA) standard, with the potential to integrate Duracell Powermat technology within every mobile gadget. The incredibly thin device resembles those wafer-like SmartMedia cards once used in early digital cameras, with a similar form factor, but significantly more practicality. Each WiCC includes all the PowerMat circuitry found in the company's charging cases, while also doubling as an NFC antenna. The card's success is of course contingent on cooperation from device manufacturers, who will need to add a slim connector above the battery leads, including two for power, two for NFC and two for data -- an app will monitor charging. Powermat reps say that such a connector would cost pennies to implement, however, making it a potentially easy sell.Powermat President Daniel Schreiber sees this as a major breakthrough for the smartphone industry, saying "we're going to do for wireless power what the memory card did for storage in mobile phones." We had a chance to take a look at a mock-up of the wireless card at MWC, which was resting just above the battery in a Samsung Galaxy S II. Because the phone's battery is slightly recessed, both the card and battery fit below the device's original backplate -- the WiCC lies flush with the phone's camera lens. Overall, we think there's some serious potential here, assuming device manufacturers are game to come on board. Still, don't expect to see these hitting stores anytime this year -- the company expects its other products to come to market long before the Wireless Charging Card. So for now, jump past the break to take a closer look, but don't make any plans to toss that power adapter just yet.
Sony Cyber-shot TX300V inductive charging camera and dock hands-on (video)
You may have thought that Sony's Cyber-shot TX200V was the company's most powerful point-and-shoot to date, but that's not exactly true. The company has a Japan-only version of the TX200V called the TX300V, and it's quite a compelling upgrade. The camera's most appealing addition comes in the form of a wireless charging and transfer dock -- it refuels your pocket snapper through inductive charging while also wirelessly transferring images to your computer using TransferJet. It can also draw power from your computer's USB port (no AC adapter required). Oh, and it ships in the camera box.Sadly, there aren't any plans to sell this iteration outside of Japan, and Sony's mum on pricing and availability. The camera transferred images and charged without issue during our demo (the Charge indicator lit up, at least -- we didn't stick around to watch it charge the camera). We went hands-on with the TX300V and its charging dock at CP+ in Yokohama, and you can check the camera kit out in all its glossy black glory just past the break.
TI's wireless charger for tablets does amazing things with electrons, sticky tape
Either TI has the hots for Arduino in a big way, or its latest wireless charging kit isn't quite ready for mass production. When it does arrive, however, it promises to do away with those cumbersome specialized sleeves and back covers that are currently needed for inductive charging. Instead, it'll deliver efficient in a package that's small enough to be installed as part of a device's internal circuitry. In addition to the Qi-standard 5W version we glimpsed a while back, the company is also working on a 10W variant for the iPad 2 and other tablets, which could wipe the smile off LaunchPort's face and perhaps make MicroUSB 3.0 superfluous before it even gets here.
Fulton Innovation powers phones in your handbag, shows off inductive charging support for tablets (video)
Fulton Innovation has a knack for coming out with the latest -- ahem -- innovations in the rapidly-expanding world of inductive charging, and this year the crew showed up at Pepcom Digital Experience to show off the company's progress in the world of wireless power. Today its offerings, most of which are still in the works and not ready for final production as of yet, include the ability to charge your handset through your handbag. In addition, it's the first company to find a way to utilize inductive charging through a metal surface; last but not least, Fulton was showing off the upcoming medium-power Qi standard, which is capable of powering up tablets. Check out the video and gallery below to see the new techniques in development for wireless charging.
Duracell Powermat hands-on (video)
Back in September, as you may recall, Duracell struck a joint venture with Powermat, as part of an effort to "advance and globalize wireless charging." At CES this week, the two companies are putting the fruits of their partnership on full display, and we were lucky enough to get a sneak peek at their latest inductive innovation. The basic idea behind the initiative is to bring wireless charging platforms to a variety of environs, including desk drawers, toy boxes and even sports arenas. In fact, Duracell Powermat are already planning to install their circular grommets (pictured above) at various locations across Madison Square Garden, allowing concertgoers and Knick fans to inductively charge their smartphones directly on a bartop. This system, however, isn't limited to the smartphone realm -- something Duracell Powermat was quick to point out, with a prototype desk drawer and toy chest, both of which are capable of wirelessly charging a wide range of devices. The companies have also developed software capable of monitoring the progress of a device's battery charge, which they displayed, in prototype form, on a tablet at their booth. Unfortunately, there's no sign that we can expect to see this technology appear in actual products anytime soon, but we were told to "stay tuned." In the meantime, check out the gallery below for some more images, and be sure to head past the break for our hands-on video. Mat Smith contributed to this report.
Fulton Innovation ready to show off new wireless charging techniques at CES
Judging by the number of announcements the company makes this time of year, Fulton Innovation absolutely loves CES. And as to be expected, the inductive charging superstars are tackling CES 2012 head-on to show off the techniques it's been working on for the past year. At this year's show, Fulton will demonstrate the ability to wirelessly charge through a metal surface, show off a car with interior surfaces enabled with the Qi inductive charging standard and display the technology being used inside a handbag. We're pretty eager to see how it all works in real life, so we'll bring you coverage as the show progresses. Feel free to gaze upon the press release below in the meantime.
Mobee's Magic Feet and Power Bar juice up Mac peripherals, no more battery swapping for you
Mobee's no stranger to the world of Mac peripherals these days, and you would've already come across the brand if swapping batteries is too much for you. Following its Magic Charger (for Apple's Magic Mouse) and Magic Bar (for Apple's wireless keyboard and Magic Trackpad), at this year's CES the company's decided to dish out an all-on-one charging station that features a second inductive charging pad plus four USB ports. But of course, there's a trade-off for this big daddy: in addition to the USB connection to your Mac, the Magic Feet also requires an AC adapter. However, given that each device has a battery life of up to 10 days only, this external power will actually come in handy for night time charging. Alternatively, if you're not a fan of clogging up desk space with a charging station, then you can consider Mobee's Power Bar. Unlike its inductive-charging counterpart, this stick simply adds a 10-day battery and a micro-USB port to the Magic Trackpad, thus letting you plug-and-charge when needed. Oddly enough, Mobee doesn't say whether the Power Bar is also compatible with Apple's wireless keyboard, but the response we received was that it isn't a matter of technical limitation; but rather, it's simply that the company believes the Magic Bar is the better solution for owners of the wireless keyboard. Well, we'll let you be the judge.
