PURPOSE: An apparatus for charging accumulators of electrical energy is provided to enable the accumulator to be completely charged while substantially reducing the risk of damaging cells of lowermost maximum capacity. CONSTITUTION: In a charger(1) to operate according to the second charging method, it suffices to dimension transformers(4.1-4.n) and rectifiers(5.1-5.n), as well as, if necessary, a source(6), in such a manner that the no-load voltage supplied by each of charging circuits(3.1-3.n) has a value substantially equal to U1/n, where U1 is the above-mentioned value specified by the manufacturer of accumulator(2), and n is the number of groups of cells(2.1-2.n), and in such a manner that the maximum current that can be supplied by each of the charging circuits is equal to the maximum current that it is desired to supply to the accumulator at the beginning of the charging operation, which is selected in dependence on the maximum capacity of accumulator and the allowable time for charging.
