"4 diferentes metodos de carga con compensacion de temperatura mas 'ecualizacion'
'Ecualizacion' de baterias manual o automatica..."

Ecualizacion = conexión de varias pilas recargables en paralelo para igualar sus voltajes y su carga. En este caso la conexión durará 3 horas.

I just found this at www.news.uiuc.edu:16080/archives/97.04/9704electronicstip.h...
\"Rechargeable batteries generally consist of a number of individual battery cells strung together in a series,\" Krein said. \"No two cells are exactly alike, and they rarely have the same charge or expend it at the same rate. Ultimately, overall performance of the string is limited by its weakest cell.\"

At present, battery manufacturers address this problem by recommending that users forcibly overcharge the string to bring the weakest cells up to normal operating levels, Krein said. \"After repeated cycles, however, this overcharging damages cells, degrades performance and shortens the string\'s useful life. We found a way to efficiently equalize the charge in these battery strings without overcharging individual cells.\"

Krein\'s technique uses a group of capacitors and transistorized switching networks to shift the charge among adjacent battery cells, similar to the way in which water fills an ice cube tray. As the capacitors are switched back and forth repeatedly, the total electrical charge is spread uniformly through the cells. The cascading effect is independent of string length, and can occur continuously during battery operation.

\"By extracting energy from higher-charged cells and delivering it to cells with a lower charge, we can bring the battery-cell voltages in a string to equal values,\" Krein said. \"The cells will remain balanced as long as the switched-capacitor system is operating, whether the battery is being charged or discharged. We expect this to significantly extend the life of the weaker cells.\"

Because the battery equalization technique is not dependent upon the normal charging process, the cells in partially charged batteries also can be brought into balance....\"

Si la ecualización se hace por medio de sobrecarga y el \"interruptor momentáneo\" inicia el proceso, entonces \"interruptor momentáneo para ecualización durante tres horas\" sería lo mejor.

Si se usa una matriz de interruptores transistorizados, entonces \"conmutación para ecualización durante tres horas\" podría ser mejor.

HTH...
