Abstract
A battery controller buffers a higher voltage provided by a primary cell in order to charge a secondary cell that operates at a lower voltage. The battery controller includes a storage device that is charged by the primary cell. When the voltage of the storage device reaches a threshold, the battery controller conducts the stored charge into the secondary cell while isolating the secondary cell from the primary cell. The secondary cell, when charged, powers a node that operates with a low voltage.
