Battry Carger

I have several old laptop batteries that are not used. I want to use the battery to make several projects. And first I need to make a charger module for the battery. Therefore, in this article I will show you how to make it

the video above contains the process of making the module. But there is some information that I didn't show like what components were used to make it.

I purposely did not display this information because I wanted to display it in this article. Besides that, in this article I will also provide several files such as schematics, layout and PCB gerber files.

below are the components needed to make the modules :

• 2* micro USB connector
• 1* 2P T-Block
• 2* Capacitor 100nF
• 2* Capacitor 10uF
• 4* Resistors 1K
• 2* Resistors 1k2
• 2* Resistors 0R
• 2* Red LED
• 2* Blue LED
• 2* IC TC4056A
• 2* 1x2 Male Header
• 2* Jumper
• 1* Battry Holder

Based on the information that I have mentioned in the video, there is a mistake in the PCB design that I made. These mistakes are:

• Pad at the bottom of the IC TC4056A is still wrapped with a Solder Mask
• There is one line that I have not connected I have resolved

I have fixed both problems. And for the files that I have provided below are the files that I have corrected. So you don't need to worry if you want to use them.

To make PCB 2 layer PCB with good quality. I use PCBWay services to make a 2 layer PCB for this project. You can see the finished 2 layer PCB in the image above

The gerber file for this design can be downloaded below

Tthis stage I really like it. because this step is quite difficult and long, that's why I like it.

For the results you can see in the image above. The figure shows that the module is charging the battery. This is indicated by a red LED indicator.

To see more detailed results, I recommend watching the video.

thank you for reading this article. see you in the next article
