BERLIN, Germany, August 31, 2023.

The Wireless Power Consortium (WPC), the leading global standards development organization for wireless power standards, is turning its attention to the emerging and rapidly expanding Light Electric Vehicle (LEV) market for its next wireless charging standard and to provide consumers and manufacturers alike with improved safety and convenience.

The WPC recently announced its new global standard for mobile devices with the Qi2 standard and will be launching its Ki standard for cordless kitchen appliances in 2024. The growing popularity of eBikes and electric scooters and the lack of a global charging standard for their rechargeable lithium-ion batteries is an opportunity for the WPC to apply its expertise to establish a universal wireless charging standard that ensures safety, convenience, and interoperability.

“A lack of a charging standard for this sector can easily lead to poor user experience and significant safety issues such as fires. A standard – like Qi2 or Ki – assures consumers that their devices are safe, efficient, and interoperable with other brands,” says Paul Struhsaker, executive director of the Wireless Power Consortium. “Consumer demand for convenience and efficiency is driving universal standards. Furthermore, standards provide consumers safety and reliability – from mobile devices to LEVs.”

Most eBikes and eScooters have rechargeable lithium-ion batteries, the same batteries that power smartphones and laptops, and can fail when damaged, overcharged, or operated in extreme temperature conditions. Batteries for LEVs though are much bigger— up to 100 times larger —than the ones in personal electronics and pose a greater risk.

The popularity of LEVs surged during the pandemic and the corresponding drop in prices made them more affordable. However, inconsistent manufacturing standards and the availability of after-market chargers that may not be compatible with the battery is leading to more fires and injuries. The dominant problems with battery charging today for LEVs include:

• The absence of a universal standard for chargers.
• The connectors on the charging cable for LEVs wear out and break.
• There exists no mobile charging alternative.

“The global marketplace – from mobile phones to the vehicles we park in our driveways – recognizes the value of universal standards,” says Ken Moore, WPC LEV group chairman. “This is an ideal time to introduce universal wireless charging standards for the LEV industry. The development and design of eBikes and eScooters are relatively new and innovations and modifications will continue to occur as the industry matures and consumer preferences are reflected in these new products.”

Blog – What is Foreign Object Detection in Wireless Charging, Anyway?

August 24, 2020August 28, 2020 Emanuel Stingu Blog, News Direct Q Measurement, FOD, Foreign Object Detection, Safety, wireless charging system, Wireless power, Wireless Power Consortium, WPC

Nobody can argue that Wireless Charging is an incredibly convenient way to keep our favorite handheld devices charged up, and to provide some remedy for battery anxiety. Wireless charging is (almost) everywhere nowadays — in our phones, in our cars, in our airports, in our restaurants and coffee shops, and soon to be in places we haven’t even thought of yet. But is it safe? We have seen internet articles about wireless charging shortening the life of your smartphone’s battery, or other ways wireless charging can harm your device. But unfortunately, those articles are not written by people who understand wireless charging, and are false and misleading. (Spoiler: There is no difference in charging your phone from a wire or from wireless — it’s just another way of getting energy.)

Back to our question: Is wireless charging safe? The answer, of course, is a resounding “yes”, provided it is done correctly. One of the biggest safety topics to understand in a modern-day wireless charger is how to prevent the wireless charger from heating metal objects to unsafe levels. Because the frequency used by the wireless charger is very effective at heating metal objects, it is up to us as system designers to ensure that any stray metal objects, such as wayward coins, that present themselves in the middle of a charging session are not a cause for alarm (as in “fire alarm”). In order to protect ourselves from these “foreign” metal objects, we try to detect this safety threat with something called “Foreign Object Detection”, or FOD.

Historically, ever since the introduction of Foreign Object Detection (FOD) methods in the Wireless Power Consortium Qi (pronounced “chee”) standard, the general public has had a misunderstanding of what FOD really means.

If a random person is asked what FOD must do, in most cases the answer would be that if a coin is placed on the transmitter surface, the transmitter should indicate the presence of a foreign object. This is basically the functionality of a metal detector.

In practice most receivers like phones and battery packs have metal elements around the receiving coil. User experience can be negatively affected if these metal elements are wrongly classified as foreign objects. According to the Qi specification, a foreign object is detected only after a Qi receiver is placed on the transmitter surface, information is exchanged between the two devices and a decision is made about the foreign object presence based on the estimation of how much power would actually be dissipated into the foreign object during power transfer. It is perfectly acceptable to have an object on the transmitter surface during power transfer if it does not heat above certain thresholds.

OBJECT PLACEMENT ON THE TRANSMITTER SURFACE

The most popular method to detect the presence of an object on the transmitter surface is the Direct Q Measurement. It monitors for changes to the quality factor (Q factor) of the transmitter coil or for changes in its inductance or resistance. Other methods that detect the presence of objects on the transmitter coil can be based on change in capacitance, light reflection or transmission, changes in weight/pressure, resonance at 1MHz, metal detectors using auxiliary coils, etc.

The Qi specification has an informative section reserved for these mechanisms. The resonance shift method is already described and is related to the change in quality factor. The fact that a resistance change is also induced by most (but not all) receivers can be used to improve the detection of the object but it is not enough to determine if the presumed foreign object would actually absorb enough energy during power transfer to cause a significant increase in its temperature.

CONFUSION BETWEEN THE DIRECT Q MEASUREMENT AND THE EXISTING PRE-POWER FOD METHOD

These values are measured when a receiver is placed on a MP-A1 transmitter coil and they are reported by the receiver during the negotiation phase.

The transmitter may not use a MP-A1 coil and in that case its measurements of Q and resonant frequency must be converted from the actual transmitter coil to how they would look like on the MP-A1 coil before a decision can be made regarding the mismatch between the measured values and the reported values from the receiver.

The Qi specification has a high-level description of the pre-power FOD methods but the mechanism used to calculate the Q factor seen by a MP-A1 coil is not provided.

The direct measurement of the transmitter coil quality factor without a receiver present can at most inform the transmitter of the existence of metallic objects on the charging surface, and the transmitter can use this data to inform the user to clear these objects before placing the receiver on the surface. This method can also be used after a confirmed FOD event and subsequent removal of power. In that case, the transmitter uses this method to ensure the user has removed all objects from the charging surface before allowing the receiver to be placed to restart charging.

This method alone cannot determine if the metallic object will consume sufficient power to heat the object, but it can be used in combination with other power loss methods to educate the user to always remove all metal objects from the transmitter surface before/during/after charging.

Confusing? The key is in the name of the action: Foreign Object Detection. It’s one thing to detect a metal object, but it’s a whole different ballgame to determine if that object will lead to an unsafe situation if we charge a phone while that object is present. As a charger, what you want to do is charge a user’s battery — that is, after all, the reason you exist. Therefore a charger must have a robust and deterministic plan for deciding which objects are clearly unsafe, and which objects can still be present during a charging cycle without cause for alarm. If I am too conservative, then nobody gets to charge. But if I am too lenient, then somebody gets burned (maybe literally). Striking the right, and safe, balance is the art of good transmitter design.

“It is perfectly acceptable to have an object on the transmitter surface during power transfer if it does not heat above certain thresholds.” – Emanuel Stingu, Chief Technology Officer at Spark Connected.

Blog – The Leap Beyond 15W Wireless Charging

INTRODUCTION

Since the public announcement of near-field coupled magnetic-field based resonant wireless power transfer (WPT) in 2006, wireless charging technology has been undergoing significant development. Since then standards bodies such as Qi Wireless Power Consortium (WPC) as well as PMA/Airfuel Alliance have been formed, among which, Qi WPC has been the main driving force in advancing and establishing the standards for the WPT and wireless charging.

Different wireless chargers including 5W legacy and 15W next-generation have been certified and utilized in the market. With the success at these power levels the industry is leaping for the next big step to hit the market with the power levels of 30W, 45W, 60W, and beyond. The application for these power levels could involve laptops, drones, autonomous robots, power tools, etc.

OPERATION PRINCIPLES

The near-field wireless power transfer operates based on the magnetic-filed coupling of the transmitter (TX) and receiver (RX) coils. The magnetic field is stablished with alternative current (ac) at different frequencies including radio frequency (RF), resonant, or near resonant frequencies, where the latter is designed for inductive charging. Figure 1 depicts a near-field coupled WPT/WC system. Depending on the switching frequency of the TX driver as well as LC tanks resonant frequency the system could be designed to operate in one of the three aforementioned operation modes.

The TX driver output is an ac voltage with a fundamental frequency at which the system is designed for. This voltage supplies the TX LC tank with an ac current establishing a magnetic field in the TX coil. When a wireless power receiver is at the presence of this filed, the coupling between the TX and RX coils induces an ac voltage across the RX coil which yields to an ac voltage at the input of RX rectifier. This ac voltage is then rectified to either charge a battery or supply a load.

The deceptively simple appearance of this system has demanded enormous effort from EE engineers to improve its efficiency and reliability in competition with the wire-based chargers. Although, 5W WC systems have shown a promising dependability and met the market’s demand, the 15W is still challenging the technology leading companies and agencies. The challenge is not only optimizing the systems for a higher efficiency but also their reliability is highly dependent on the communication system between TX and RX. The communication system provides a negotiation mechanism through which the TX and RX establish a power transfer agreement. The traditional communication between the TX and RX in the 5W systems has been based on a low-bandwidth in-band communication where the message is modulated on top of the power signals at its origin and then is demodulated from the power signals at its destination. The in-band modulation is usually implemented through amplitude shift keying (ASK), frequency shift keying (FSK), or phase shift keying (PSK), or a combination of these methods. It can be conceived that this communication method could be affected by the dynamics of the power signal. Therefore, the gateway to the higher reliability of WC systems at power levels of 15W and beyond is enhancing their communication robustness independent from the power signals dynamics and therefore improving overall system reliability. The possible solution could be the out-of-band communication with high bandwidth and bit rate such as Bluetooth, NFC, or similar technologies.

Development of higher power WC systems for applications where simultaneous power and data transfer are needed could be a revolutionary transition to a cord-less world. The application of these WCs in consumer electronics, especially in laptops would be the beginning of an integrated wireless charging and data transfer unit. In this outlook a transmitter unit, e.g., a laptop docking station at the power levels of 45 – 200 Watts could be utilized as both power and data transfer wireless link. At the front-line of battle between the wired and wireless world a technology leader such as Spark Connected is fulfilling its mission towards Powering the world, wirelessly™ by developing the most advance and reliable 45 – 200 Watts WPT and WC systems.

Ken Moore - Silicon Review's 30 Best Leaders To Watch 2020

May 14, 2020 – The Silicon Review

‘Powering the World, Wirelessly’: Spark Connected, a Dallas-based Tech Firm, Transforms Wireless Power Delivery and Battery Charging with Innovative Platforms, Disruptive Technology, and Breakthrough Products.

During the 1980s, the Ethernet cable was the biggest innovation of the decade. It let users connect to the World Wide Web and took them places they’ve never been before. However, when WiFi was invented in 1998, people moved away from Ethernet cables to WiFi as it promised wireless connectivity at better speeds. Importantly, having portable connected devices that are battery operated and can be charged wirelessly is the latest trend to hit the technological market.

In light of the above, we’re pleased to present Spark Connected – a pioneer in the wireless power industry.

Spark Connected was founded with a purpose to transform wireless power delivery and intelligent battery charging with innovative platforms, disruptive technology, and breakthrough products enabling an enhanced user experience for all.

The company specializes in product development and engineering solutions with a team of innovators who have over two decades of combined deep domain experience. Spark takes pride in delivering advanced end-to-end wireless power system solutions that benefit industries and markets as diverse as industrial, medical, automotive, telecom and consumer areas.

In Conversation with Ken Moore, Spark Connected CEO

Can you brief us about the history of your company?

Spark Connected was founded in 2017 in Dallas, Texas. With a focus on specialized product development and engineering solutions, the firm has produced cutting-edge inductive and resonant wireless power and charging solutions. We are early pioneers in creating safe products, passing and exceeding regulatory requirements. We have partnered with Infineon Technologies, AG and area full member of the Wireless Power Consortium (Qi). Our Spark team members hold WPC co-chair positions in the Mobile Laptop, Automotive and Next Generation Transmitter committees, where we help guide the future wireless power standards.

What is your greatest fear and how do you manage it?

My biggest fear in both technology and business is to stop moving forward. There is an old saying that some people are like sharks. A shark must continue swimming forward to breathe through its gills, and if a shark stops swimming, it will die. Technology is very similar in the sense that if you aren’t moving forward and innovating, then eventually you will lose your value in the market and be relegated to the dustbin of history. Spark is all about innovating faster than our competitors, who are often much bigger than we are.

What were the biggest initial hurdles to building your business and how did you overcome them?

The biggest initial hurdles to building our business were funding and market awareness. Funding a startup in the post-2008 era is difficult, and making customers aware of your existence in this information-overload age is even more difficult. To solve the funding issue, we took the self-funding route. I would not recommend this road for those who value their peace of mind, but in business, you often have to place bets on your vision and your ability to execute. For market awareness, there is no substitute for good old-fashioned relationship building and word of mouth campaigns.

‘It is difficult to start a venture, but far more difficult to maintain it’. How would you and your team interpret this saying?

This goes back to moving versus standing still. In the beginning, everything is new and exciting. But very soon, you have to execute on all those promises you made to the market. So you now have to maintain your focus on innovating ahead of your competition, while still executing so your current customers can develop their products. This is a delicate balance that many find difficult, if not impossible. As a leader, if you have done your job by building a strong team around a clear strategy, you can make the present a reality while still keeping your foot on the accelerator and moving forward.

If you had one piece of advice to someone just starting out, what would it be?

Talk to someone who has done it before (and been successful), and make them your mentor. It will save you quite a few stubbed toes and smashed thumbs.

What do you think is the most memorable moment in your career?

The most memorable moment would be when I received my first promotion ever to lead a team. It changed me in ways I never thought possible. A team is a very effective mirror that forces you to try and be a better leader, and a better person.

What are your future focus areas?

If our technology can improve the user experience of someone who is trying to power or charge a device, then that is where our focus will be.

The Visionary Leader of Spark Connected: Ken Moore

Ken Moore, CEO of Spark Connected, has always been interested in taking things apart. Alarm clocks, radios…whatever he could get his hands on. Then in the mid-1970s, his father brought him to “bring your sons/daughters to work day”, and sat him down in front of a very early computer terminal. He ran a program and the computer asked Ken his name. When he did so it responded “Hello Ken, my name is PDP. Would you like to play a game with me?” Ken was completely fascinated by that funny green TV that seemed so alive, and after that it was all about technology.

Ken went on to attend the University of California, Irvine, where he received his BS in Electrical Engineering, and the Cox School of Business at Southern Methodist University where he received his MBA. Ken has been elected as the Co-Chair of the Wireless Power Consortium (WPC) Mobile Laptop Task Force.

“If our technology can improve the user experience of someone who is trying to power or charge something, then that is where our focus will be.” – Ken Moore, Chief Executive Officer at Spark Connected.
