How to make wireless charging from wired (simple)?

Michael asks:
I have an electrical circuit (pictured). This is a phone battery charger circuit, but unusual. Ever encountered car charging for a battery? This type of box with an ammeter and crocodiles. Here I have something similar, but for the phone.

Its peculiarity is that it charges the battery with a pulse current, and not constant, like ordinary charges. So, there is a circuit diagram for it, I can send it, there are several microcircuits, a digital timer, a generator, power, resistors, a field-effect transistor, etc.

I need to make wireless charging from this phone charge by adding something to the circuit. Those. so that she charges with a pulsed current, but at the same time as modern charging without wires.

But I need this in view of the fact that it is terribly inconvenient to pull the battery out of the phone and clamp it with crocodiles. Now either wired charging is relevant, but it’s better still wireless, I took the phone and it charges you with a pulsed current, and, as I heard, it’s useful for the battery, because it restores its capacity and does not allow oxidation or something that kind of thing. Is a solution possible in this situation?

The answer to the question:
A solution may be possible, but simply by “adding something” we won’t get off here. First, you need to understand that wireless charging is two inductors (two coils). In simple terms, when you put the phone on the base (let's call it that platform for wireless charging, I hope you understand me), the coils interact with each other like windings of a simple transformer. An alternating current flows with a high frequency in the database (it is a transmitter), as a result of the receiver coil (the one on the phone) being in its magnetic field, the same current arises in the latter. Charging in progress. It follows that the principle of operation described above is not the same as that of the circuit you quoted
You have complicated the task, and significantly, it’s cheaper, faster and easier to buy for a couple of hundred - half a thousand wireless charging with aliexpress.

Secondly, of course it is possible to realize charging with a pulsed current of a telephone battery, but why? This method of charging was often used to charge lead, metal hydride and other types of batteries, which were used in the technique earlier. For charging lithium, special algorithms are used, one of them is implemented on the tp4056 regulator chip (this is one of the most common, simple and cheap options), by the way, using this chip, you can restore charging through the native connector, look on YouTube for the video “REPLACING THE TABLET CHARGING SYSTEM (when there is no room for a fee). "

Thirdly, why bother? What kind of phone do you have that you need to remove the battery? Why does the regular charging through the connector not work? To simplify life, in this case they use either universal wireless charging (inserted by a plug into the micro-usb connector) or cords with a magnetic plug.

I apologize if you did not like my answer, but with a similar question you will be better helped on any profile forum, in the section where power converters and power supplies are discussed.
