Today, I am excited to present to you an innovative and highly efficient lithium-ion battery charging station. Unlike anything you have seen before, this charging station is designed to charge up to 10 cells simultaneously while ensuring maximum safety and convenience.

One of the standout features of this charging station is its built-in overcharging protection mechanism. This means you can charge your batteries with peace of mind, knowing that they will not be subjected to excessive voltage that could potentially damage them.

Additionally, this charging station incorporates a voltage monitoring system that allows you to individually check the voltage of each battery. This feature is incredibly useful for assessing the health and performance of your batteries, ensuring that they are in optimal condition before use.

Furthermore, this charging station provides real-time power consumption monitoring. You can easily keep track of how much power the station is utilizing, giving you valuable insights into energy usage and efficiency.

By combining these advanced features into one compact and user-friendly design, this lithium-ion battery charging station sets a new standard in battery charging technology. Whether you are a hobbyist, a professional, or simply someone who values convenience and safety, this station will revolutionize your battery charging experience.

PCB Designing - 

PCB Layout – 

                    After Creating the design now it's time to order our PCBs I am going to order my PCBs from “ ALL PCB ”  because “All PCB”  is the world's fastest PCB manufacturer. After placing the order I received my PCBs within 1 week.

Components Required – 

 

To build This you will need the following components:

1. TP4056 Charging Modules 
2. 18650 Battery Holder
3. Volt Amp Meter
4. Volt Meter
5. On/Off Switch
6. 10 PIN DIP Switch
7. 2-pin Screw Terminals
8. XT60 Connectors
9. Male Header Pins

 And we need a few components like charging modules, switches, voltmeter, st60 connectors, on/off switches, volt map meter and so on.

Assembling the PCB

To connect the charging modules here I am using these pin headers. because while charging these modules often get hot so I decide instead of direct solder them into the board it will better to use these headers so that there will be an air gap.

Now i will connect all the push-button switches to the board. By using these switches we can turn on or turn off the charging.

Now one by one I will connect all the battery holders. These the PCB-mounted battery holders made for 18650 batteries.

Now lest come to the bottom part of our PCB here for power input I am using a 2pin screw terminal and XT60 connectors. 

And to monitor the input power supply I have added a volt amp meter and a 10-pin DIP switch to control all cells and a mini volt meter to measure the voltage of all batteries.

To hide these wires and to prevent any kind of short ckt  I will ad another pcb, and using some M3 spacer it will be easier for me. and as you can see after adding the 2nd layer we don't need any casing for this charging station. Now it's time for testing so let's test our changing station and hopefully everything will work fine.
