In a hybrid power supply device constituted such that a secondary battery ( ) is charged by a fuel battery ( ) and electric power is supplied from the secondary battery ( ) to a load ( ), even when there are variations among residual capacities of individual unit secondary batteries ( ) constituting the secondary battery ( ), the secondary battery ( ) can be charged properly without causing overcharging in each of unit secondary batteries ( ). The fuel battery ( ) is divided into a plurality of unit fuel batteries ( ), each consisting of a predetermined number of cells, and each unit hybrid power supply ( ) is constituted by connecting each unit fuel battery ( ) with each unit secondary battery ( ) through each charging switch ( ) in parallel. The charging switch ( ) is controlled independently for each unit hybrid power supply ( ) on the basis of the residual capacity of each unit secondary battery ( ) to perform charging of the unit secondary battery ( ) by the unit fuel battery ( ).
