Battery Balancing System and Method (PCT/AU2014/000800)

Abstract

Provided is a battery balancing system arranged to be electrically connected to an external load and an auxiliary load, the system comprising a plurality of cell units, each being arranged to be connected in series with; i) the external load, or ii) the auxiliary load. The system also comprises a controller arranged to determine the state of charge of each of the cell units, and an electrical connection mechanism associated with each cell unit and arranged to be controlled by the controller' based on the determined state of charge of the associated ceil unit, wherein during a discharge cycle of the cell units each electrical connection mechanism is arranged to: I) electrically connect its as..
