Qi charger for any phone / smartphone and general gadget
Good day, Habr!
I have not had a thought to buy a wireless charger for my phone for a long time. There is only one problem - my phone does not support the wireless charging method, it does not have pins behind the back cover for connecting the receiving coil (we will call it the receiver) and the compartment for it. So I decided tobuy a new modify phone. I have a Fly IQ454, but the handset of the Samsung Galaxy Ace 3’s wife also turned out to be on hand, so it was decided to start with it ...
First of all, a month ago I ordered a wireless charger on a well-known site. Included with the charging (transmitter) was a USB-> microUSB cable and (most importantly!) A receiver for embedding it into the Samsung Galaxy S3 phone (this phone has both contacts and the distance under the cover is available). The inscription “Qi” proudly appeared in the name of the product. For those who do not know: Qi ("Qi") is a standard developed by the Consortium of Wireless Electromagnetic Energy (Wireless Power Consortium, WPC) for inductive energy transfer over a distance of 4 cm.
Below are photos, I want to apologize for the quality of the soldering; for a number of reasons I did not have a soldering station at hand, but it turned out to be a 60W soldering iron, which I got into the phone with (I will try not to do this again).
Connect the coil in three ways:
1. Directly to the battery (in this case there will be no charging indication).
2. Connect to the charging connector of the device (the sense of wireless charging is lost, or there are wires stretching from the connector under the cover).
3. Solder the coil to the power connector pins on the side of the board.
Of course, I chose the third option.
As I did not try, the wires did not fit between the board and the case (the diameter was too large), but you caught the gist. It was decided to change the wires to thinner ones and it turned out something like this:
Then (do not forget to look at the polarity and sign) soldered the receiving module to the output wires.
The cover, I must say, was closed barely. When there is no phone in charge, one red standby indicator is lit. When we put the phone, it still lights up green.
Two days, the flight is normal. The phone was recharged for 20 minutes, then left for the night. In the morning, safely removed from the charge with full battery. In the passive mode, the charge is not heated at all, in the worker it is heated, but not much.
If someone is interested, the module of the receiving part is made on the BQ51013A, but the transmitter is on the HB898A, which put the Qi standard in question. In my opinion, the transmitter should have been based on the BQ500210 (also from TI).
Price issue: 535 wooden.
