Abstract :
There is a need for shortening the time of formation of the batteries at the production line, and this is due the great demand of this product. In this paper we are proposing a novel technique in this area to optimize the time of manufacturing. This technique uses a fuzzy logic approach to increase the ampere rate in order to minimize the formation time. This paper shows a fuzzy logic system for the formation of batteries using a high scale integration device, such as the FLASH PSD813F1, which is a micro-controller. It includes a CPLD (COMPLEX PLD) embedded, which allows implementing logical functions defined by the user in its 73 inputs 19 outputs AND-OR array. The fuzzy logic algorithm is summarized in a look-up table, described by Boolean equations implemented in the PSD813F1 CPLD. The fuzzy controller, for the formation of batteries for the CPLD of the PSD813F1, basically controls the current intensity applied to the battery depending on its temperature and the change of temperature.
