METHOD FOR ANALYZING NICKEL-CADMIUM STORAGE BATTERY FOR SUSCEPTIBILITY TO UNWANTED TEMPERATURE RISE

摘要

FIELD: electrical engineering; analyzing nickel-cadmium batteries for susceptibility to unwanted temperature rise.;SUBSTANCE: proposed method involves measurement of battery inherent ohmic resistance. The lower the latter, the more developed are dendrites within separators and the greater is battery susceptibility to unwanted temperature rise. Newly introduced is formula of battery susceptibility to unwanted temperature rise in the form of = (₀ )/_{0 *} 100%, where is coefficient of unwanted temperature rise; ₀ is inherent ohmic resistance of new battery; is inherent ohmic resistance of battery at test moment.;EFFECT: ability of qualitative estimation of battery susceptibility to unwanted temperature rise and for rejecting batteries whose temperature rise is most probable.;1 cl, 2 ex
