FIELD: electrical engineering; servicing nickel-hydrogen batteries in off-line power systems.
SUBSTANCE: proposed nickel-hydrogen storage battery has n series-connected cells shorted out by means of bypass diodes in charge and discharge directions and by throwaway shorting devices. Proposed method includes conduction of charge-discharge cycles and shorting of defective cell by means of throwaway shorting device. Prior to shorting bypass diodes are checked for current carried by their circuits and check results are referred to in shorting the cell, heating elements of throwaway shorting device being inserted in bypass-diode circuits.
EFFECT: enhanced reliability and facilitated procedure of shorting defective cell.
