Century Old Mobile Phones Can Be Charged Like the Car Chargers. Here is Wireless Mobile Battery Charger Circuit, Commercial Kits and Theory. The whole stuff fall in the domain of wireless power transfer (WPT) or wireless energy transmission. We have to write the guide for all type of readers. Not all can understand what to do if we start from drawing circuit diagrams. It is actually quite easy thing.
The Wireless Mobile Battery Charger System uses one coil with small circuit inside the mobile phones launched after October 2012 and the external charger unit. Ready to use Wireless Mobile Battery Charger units are definitely available. They have two parts. First part is receiver module which has one end to get inside your mobile’s charging port, that is sold as Qi Wireless Charger Charging Receiver Patch Module. That thing makes the mobile phones launched after October 2012 which lacks the module compatible to the Wireless Mobile Battery Charging Pad. Second part is the wireless mobile battery charger aka Wireless Mobile Battery Charging Pad, which will get connected to USB port or mains. First part and Second part has no connection. Quite simple. First part also sold as external unit. It is possible to make all the stuffs a DIY or semi-DIY.
Wireless Mobile Battery Charger : Circuit, Kits, Theory
There are two type of standards – Qi Standard PMA Standard. We are talking around the Qi Standard as the Standard is open. PMA means Power Matters Alliance, which is under the IEEE Standards Association (IEEE-SA) Industry Connections. Qi pronounced as chee, Made in China word. It means natural energy. This is that

We told you that these falls among the domain of wireless power transfer (WPT). Inductive and conductive charging are two types of wireless charging. Inductive is easiest. Greater distance between sender and receiver units needs resonant inductive coupling.
In inductive charging an induction coil which produces an electromagnetic field via the charging unit, where the energy is transferred to a corresponding induction coil. This we described as second part above. The electronic device to be changed receives the energy from the magnetic field and then reconverts it into usable electric current which charges the device’s battery. This we described as first part above.
Obviously, the potential energy loss makes it less efficient. Here is official specification :
Here are more on inductive and resonant :
In other words, while building the stuffs or buying them, ideally you should stick to the official Qi Standard.
Wireless Mobile Battery Charger : Circuit
Wireless Mobile Battery Charger Circuit needed for those who will use 100% DIY work. We are including a circuit diagram plus giving a detailed link with instruction for PCB, it is so great that we need not to re-write :
Wireless Mobile Battery Charger : Circuit Kits
Actually we are towards telling to buy Wireless Mobile Battery Charger Kit with Hidden Internal Receiver Module. Because the technology is too easy but making such coil manually is an absurd idea. MicroUSB Wireless Charging Receiver Film Module is available on Amazon, Ebay for $10 and allows you to add Qi wireless charging to any gadget with a microUSB charging port. For Nokia mobiles, Samsung mobiles the Qi wireless charging film module is different at connector end. You should be careful about the type of connector. Work is itself DIY. But, it is better to have the receiver as ready to use for a practical size. You can create the Wireless Mobile Battery Charging Pad as size will not matter.
