1. In combination with a primary source of high energy and low power supplying a low current intensity and a chargeable terminal output storage battery of high capacity capable of supplying a direct current output of desired much higher current intensity to a load, a plurality of intermediate electrochemical d. c. current increasing stages each comprising a storage battery of substantially lower capacity than the terminal output storage battery and each being capable of being charged by said low intensity current from said source, means for for connecting the respective batteries of said stages in sequence to said source to be charged sequentially by said current of low intensity from said source, the batteries of said current increasing stages when charged each being capable of supplying a charging direct current of intensity intermediate said current of low intensity of said source and said desired supply of higher intensity from said output battery to a load and capable of charging said output storage battery and switch means for connecting the respective batteries of said current increasing stages in sequence to said terminal output storage battery to charge the latter by a current of said intermediate intensity successively derived from respective batteries of said current increasing stages, the relative ratio of said low current intensity supplied from said source and said desired higher output current intensity being of the order exceeding several hundreds.
