Abstract

A battery system for efficiently operating a battery under various circumstances, such as relating to extreme temperature ranges and varying load (i.e. current) ranges. The battery system generally includes at least one first cell having a first chemistry, at least one second cell having a second chemistry and a controller in communication with the first cell and the second cell. The controller is adapted to employ a chemical reaction of the first chemistry in the first cell or the second chemistry in the second cell. The first chemistry is different than the second chemistry, wherein the first chemistry and the second chemistry may be adapted to provide current over varying temperature ranges or to provide current for varying current loads.
