A simple battery chemistry identification and implementation technique for a self adaptable charger

This paper covers practical implementation of battery chemistry identification algorithm for self-adaptable intelligent battery charger by using terminal characteristics only. The algorithm suits well for systems with low processing power. In this work the algorithm used for identifying battery chemistry is described in detail supported by experimental result obtained for different battery chemistries for different manufactures. The difficulty face in practical implementation and the techniques used to overcome them are also described. Furthermore, it discusses the implementation of the practical algorithm in two different systems. First the computer based implementation for more rapid development and for troubleshooting. Then the microcontroller based final implementation for portable consumer electronics.
