Abstract:
1. A method for charging batteries comprising the steps of: connecting a battery electrically to a battery-charging apparatus; dispensing electric power to the battery by means of said battery-charging apparatus; and regulating electric current and voltage dispensed by said battery-charging apparatus to the battery, wherein said regulating step comprises the steps of detecting the voltage at terminals of the battery and regulating the voltage dispensed by said battery-charging apparatus, during a constant-voltage battery charging phase, depending on the voltage detected at the terminals of the battery to compensate for parasitic voltage drops existing between said battery and said battery-charging apparatus, wherein said connecting step comprises providing contact means of said battery-charging apparatus for dispensing electric power to said battery and wherein said regulating step further comprises providing further contact means for transmitting in digital form said voltage detected at the terminals of the battery to controlling means to regulate the voltage dispensed by said battery-charging apparatus.
