Abstract

A system (400) comprising a reconfigurable array of electricity generating cells (302) for charging a battery (410); an array switching means for dynamically reconfiguring the array; a means for DC-DC conversion (312) of an array output voltage; and a means for altering the DC-DC conversion; wherein both the array switching means for array configuration and the means for altering the DC-DC conversion are modified in dependence on a battery terminal voltage.
