I have been recycling batteries for a bit over a year now. I have created a Web Based Database where I can add battery types, batteries, battery packs, faulty batteries and discharge records. I barcode label every battery (except for the ones that fail initial tests, I still add the battery in the database with the fault code) and I use a barcode scanner to input and output the information of each battery. I am currently working on a bulk 16x Charger Dis-charger that has a barcode scanner attached and an Ethernet connection to the Database where it will be fully automated.

Ah bugger this is my first post can't post links ye will put it in a second one.  Smile

Cheers Brett

Charger update-

Temperature sensors configured
LCD 20x4 configured

No - barcode scanner or Ethernet yet

Hi Brett,

nice work so far, congrats. The temperature sensors on your pics, are those DS18B20 1Wire-Bus? If so, what's your experince with more than 10 on a bus? Do you use the parasite power mode? I'm planning to use them for my next battery pack generation and will have 25-100 on one bus...

Cheers
Oliver

Hey Oliver,

I use normal power mode. I have had no issues with these at all. The hardest part was getting the Serial Number for each individual DS18B20. Here is a board design for the 16x DS18B20.

Cheers,
Brett

If you do, you just need to take two pictures of the new cells Smile

Sure will do. I also do Lipo do you want any of those?

Video 
This is a video with a bunch of photo's and short video clips of my progress of building a smart charger discharger. 
I am using 3.3ohm resistors for the discharge and TP4056 modules to discharge and it is controlled by an Arduino Micro controller. The current prototype version uses an Arduino Mega and processes 8x cells independently. I am currently in the process of designing a PCB version that will process 8x cells.
The sequence is:
• Check for a battery to be inserted
• Get the battery barcode via a barcode scanner
• Charge the battery
• Check the milliohms of the battery
• Rest the battery for the set duration (if the battery needed charging)
• Discharge and record the milliamps
• Recharge the battery
• Competed cycle uploads the battery information to my database – wait for battery to be removed then it restarts the cycle back to check for a battery to be inserted

The battery will be considered Faulty if:
• Milliohms is less than 1000mAh
• The temperature exceeds the threshold of 10°C during Charge, discharge and recharge cycles.
• Milliohms if greater that the threshold of 500 milliohms
• Charging time is 8 hours
Components and modules used are:
Arduino Mega
8x 3.3ohm Resistors
8x TP4056
8x Logic Level FET’s for Charge, Discharge and Battery polarity protection.
W5500 Ethernet Module
USB Host Module for the Barcode Scanner
2004 20x4 Blue LCD with SPI
Rotary Encoder for cycling LCD menus
9x DS18B20 1-wire temperature sensors
5V 20A Switching power supply
8x Custom PCB Charge Discharge Modules
PCB’s, dupont wires, passive components, heat sinks and mounting hardware.

Awesome project! Subbed and left a comment on YT. Maybe you should rename the post or make a new one including your cell processor so it gets more hits. My only recommendation is to use higher efficiency to charge the cells.

-figuring out which UPS I want to design a pack for (will be 24v 7S)
-building a DIY 6 bay charger and 6 bay discharger to start processing 18650's and other flat cells
-wants to power 90% of devices with PoE.

Just moved the Charger / Discharger to a new thread if anybody is interested. Cheers
