My project was started some weeks ago.
I am planning to make a dis/charger tester to spit out every aspect of a cell in one go by using simple electronics and simple logica.
So far i have done testing the psu what is working and what is not working and why.
I have done some testing on those charging chips and discharging units.
See other posts of mine.
So its time to start with the build.
I chose a different approach because i dont like to take the cells in and out there holder.
The cells must "walk" between different stages of charging and discharging and testing, to get a decent figure of what there capisity is and remaining life left.
First the built of the bay's, i dont know if this is the proper name for it? suggestions are welcome,
Sorry i did not make any pics from my saw table, forgot.
As mentioned before i am a carpenter by trade, so dont look to close at the wood work :angel:
I made several of those, time to get the sticky stuff on it, there are not much glue brands that will stick on that plastic cell holders
Time to solder some
I am going to add some sensors that will lite up a led when one is getting to hot.
That safety feature will get a own power line.
Why so much? I will charge them first and wait one week to check on the volt, then they will be on the board.
As the project wil form i will post more pictures and info.
This dis/charger tester is designed to do threethings, in one go, SOH% plus capacity, with ir in one go,30 cells a day when i am home after workand not a sleep.
Sorry, the bay with the screws in them was the prototype. they dont have any screws in them.
The sensor must still be added, and the wire's are 0.75mm and even in length, oke they will be at max 3mm in difference in length
