Abstract
A power generating system is described including a plurality of electrochemical cells. The cells are generally arranged in sections that are selectively activated individually or in combination to produce power from selected cell sections. A method of generating power is also described. A first group of one or more electrochemical cells of an array of cells are selectively activated based on requirement of an associated load. The system switches to a second group of one or more electrochemical cells of the array when the first group is discharged.

11. A method of generating power comprising:
-
selectively activating a first group of one or more groups of primary electrochemical cells of an array of such groups of cells based on requirement of an associated load, wherein the at least one group is allows to self discharge after connection with a load if the load demand halts; and
switching to a second group of one or more electrochemical cells of the array when the first group is discharged, or removing the connection to the load if the load demand halts. - View Dependent Claims (12, 13)
