This is a free software/hardware charger for lithium manganese dioxide rechargeable button cells (ML2032, ML2016, ML1220). It uses an Atmega8 microcontroller and is designed for maximum safety.
WARNING: THIS CIRCUIT AND ITS SOFTWARE IS IN DEVELOPMENT! DO NOT CHARGE BATTERIES WITH THIS CIRCUIT!
- Alpha stage: The circuit is able to charge capacitors (supercaps) up to 3.1 volts. The software for undervoltage and overvoltage protection and overtemperature protection is working. The circuit is on a breadboard.
- Beta stage: Charging ML2032 cells is working on a breadboard. A defined number of charging tests is passed without errors. PCB design starts.
- Release candidate: The circuit prototype is on a circuit board. A defined number of charging tests is passed without errors.
- Release: Small fixes and improvements from the release candidate.
