A battery monitoring system for monitoring cells in a battery bank where the cells are interconnected between output terminals, the system having: a controller having a plurality of current sinks that are operable to supply an alternating current of a predetermined magnitude to the bank such that the predetermined current is caused to flow through the cells; and a plurality of transducers arranged in series with one another and coupled to the controller, wherein each transducer is coupled to electrodes of an associated said cell and each said transducer being adapted to measure cell characteristics and the impedance between an electrode of an associated cell and a link connected to the electrode, at least some of the plurality of transducers being powered by cells of the bank, the transducers functioning to transmit information to and receive information from the controller, the transducers measuring characteristics of the cells when the predetermined current flows through the cells. |
