The recent article (here) about Powermat’s release of their Charging Spot 4.0 to add the support of Inductive Qi standard (MI based) on top of their existing support of Airfuel Inductive standard (still MI based) is a very straight forward move in response to Apple’s announcement of Inductive Qi support. Is this move the holy grail to solve the current world’s real problem? Not quite. Given the fact that Resonant Qi is still fighting the laws of physics to maintain backward compatibility, until it’s done, the real world still need a solution NOW that works for all kinds of user situations. JJPlus agrees with Powermat’s move to support both wireless power standards’ MI based devices, however, we believe that by maintaining the advantages of AirFuel Resonant (MR based) while adding an extension to support Inductive Qi is a better approach.

A hybrid wireless charging system

jjPlus WCTC301 (under table) and WCRB401 (above table)

The objective of our hybrid wireless charging system is to meet the following 6 criteria:
1. Full spatial freedom
2. Under table transmitter installation/no drilling
3. Resonant power through thick surfaces of different types
4. Multiple devices charging, one single transmitter
5. Full compatibility with both Inductive Qi and Airfuel Resonant
6. Legacy support to still billions of phones requiring wired charging

To meet the above-mentioned criteria, we start off with the abundant power of WCTC301 wireless power transmitter charging base with the capability to 1. provide 16W of resonant power through a distance of 46mm, enough to charge up to 2 phones simultaneously and 2. under table installation to power through a typical thick table. Second, we designed a ‘Power bridge’ WCRB401 which is a Qi compliant transmitter stand (for charging a Qi compliant phone) that receives the resonant power, at the base of the stand, from WCTC301. When this Power Bridge is placed within WCTC301’s effective charging area, full spatial freedom is supported and the user can still operate the phone while charging in the upright position. For legacy support, we offer an optional 3-in-one cable with selectable Lightning, Micro-USB & Type C connector on one end, and the other end connects to the power bridge. With this hybrid wireless charging system, all of the 6 criteria are met – No compromises on delivering compelling user experiences. No compromises on full compatibility and No compromises on supporting legacy devices!

(note: for infrastructure deployment, WCTC301 is equipped with WiFi connectivity and the API necessary for the remote management of your wireless power network)

Examples of jjPlus' public wireless charging hotspots

jjPlus wireless charging systems have been installed in public places such as coffee shops, convenience stores, bars, fitness centers and so on. For example, FamilyMart, one of the largest convenience store chains in Asia, has jjPlus’ systems installed in its 1,000+ stores in China’s Hangzhou and Chengdu cities.  Each store can provide, typically, 8 simultaneous wireless charging sessions via WCRB401 or WCRDG04 from the transmitter choice of either WCTC301 or WCTC202.

Transition from charging base to surface-area wireless power system

With a breakthrough in the design of antenna and power amplification circuit in the wireless power transmitter, this demonstration of surface-area MR wireless power system by JJPlus and EPC is intended for furniture makers and hotel chains for their consideration of a possible wireless powered bedside table – A wood veneer measuring 21 by 11 inches fitted, underneath, is JJPlus WCTP401 Airefuel Class 4 PTU with a flat-area antenna spanning the width of the wood which forms part of the resonator circuit driven by an advanced power amplification circuit with a total 30w of resonant power.  Multiple devices, fitted with MR receivers, can be powered at the same time with arbitrary placement on the surface of the wood.  A lamp, a baby monitor, an alarm clock, a speaker, a smart watch (and a phone which has just been taken off) are the examples of the possibilities. (note: WCTP401 can also be packaged as a “surface-area power pad” for applications such as a gaming pad or a work-desk power pad. Creating a wireless powered hotel suite is now one step closer to reality! 

Get a load of WCTP401’s antenna!

In order to provide resonant power to a large surface area without interference to the surrounding devices, the magnetic field has to be confined within about 2 inches from the surface while spreading across the surface evenly.  With precise calculation and simulations, the interlocking honeycomb antenna design manipulated the magnetic field perfectly providing 100% spatial freedom for multiple devices “drop-and-power” users experiences.
