Circuit arrangement for the parallel operation of battery, wherein each battery charger comprises respective pairs of direct current output terminals for connection to the battery to be charged, and between said pairs of output terminals a repetitive sequence of pulsating direct current voltage can be measured, and the peak values of the pulsating direct current voltage is higher than the nominal terminal voltage of the battery (B), and each battery charger (Ch1, Ch2, . . . Chn) comprises in series with the current path at least one electrolytic capacitor (C1, C2, . . . Cn), an inductance (L1, L2, . . . Ln) and at least one semiconductor means (D1, D2, . . . Dn) open in the direction of the charging current, the output terminals of the battery chargers are connected in parallel with each other and for each of the battery chargers (Ch1, Ch2, . . . Chn) it is true that in the respective charging periods the vectorial sum of the instantaneous voltages on the electrolytic capacitor (C1, C2, . . . Cn) and on the inductance (L1, L2, . . . Ln) reaches the momentary terminal voltage of the battery at least for the duration of a charging period defined by the actual voltage of the battery (B) to be charged, and during the charging period or a part thereof the discharging current of the electrolytic capacitor (C1, C2, . . . Cn) in the particular battery charger flows in the battery (B) to be charged.
