СПОСОБ АНАЛИЗА НИКЕЛЬ-КАДМИЕВОГО АККУМУЛЯТОРА НА ПРЕДРАСПОЛОЖЕННОСТЬ К ТЕПЛОВОМУ РАЗГОНУ

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 eta = (rho0 rho)/rho0 * 100%, where eta is coefficient of unwanted temperature rise; rho0 is inherent ohmic resistance of new battery; rho 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
