It includes the software and a couple of charge logfiles (CSV). All actual hardware control will be disabled, because no hardware is connected.
It is possible to look around in the software, load the logfile and play with the chart and table display.
It is the exact same version software that I use at the moment, I have neither added or removed anything for this demo version. I have tested that it starts on Windows and Linux.
To use/test it a working Java version 1.8 or newer must be installed.
I have mounted all the PCB’s, the one in the frame is still in the frame and working.
The software has got a few updates and I have made it more general. This means it can read any CSV file with a voltage and current column and show it, if the file include a timeStamp column counting seconds it can calculate capacity and energy if they are missing in the file. The software do not care if the file is from a charger or discharger, it will work with both.
The link in post #44 points to the updated software now.
I am working on the article about the charger, but I do not know when I will be finished.
I did have time to a few software update, The IR curve can be calculated for any charge/discharge curve with pulsing current. The chart can either be saved to disk or copied to clipboard, both in a couple of resolutions.
Use the link in post #44 to get the software.
It is fairly easy for me to add support for other chargers/dischargers as long as they generate a CSV file. To get support email me a couple of CSV files together with a list of charger and software used and I will look at adding it. My email is info@_something_with_lygte
The acrylic holder is generally fine, the issues I have:
It is slightly difficult to mount batteries in it, there is not enough space beside the battery for my fingers.
It will not fit 32xxx batteries
The front can melt when running hot.
Ad 3) I do still use them, but have replaced that piece of plastic with something that can handle high temperature. This means the inside of the battery connection piece sometimes melts and I have not found any place to buy spares, I do not believe the aluminium will handle this better.
You start it from the computer and you can log from the computer, the charging is controlled locally by the charger. If it looses power or is reset it will always start in idle mode.
It is not a safe charger, you can ask it to do anything within its range. I.e. if you ask to charge a LiIon battery to 4.4V it will do it. It do have a safe LiIon and safe NiMH mode.
I have published the project, it can be found here: Computer controlled battery charger
I have at the current time 5 of these chargers and they all work nicely.
If anybody want to ask or discuss about this project it be done in this thread.
