| titleOfInvention | Lead cell designed for operation at sub-zero temperatures and method for its charging |
| abstract | FIELD: electrical engineering; lead-acid cells and batteries of intermediate discharge class. n SUBSTANCE: proposed cells and batteries are of intermediate discharge class M according to up-to-date International Classification. Novelty is that active material of negative plates is doped with activating additive incorporating 2.5 to 3% of antimony, 0.4 to 0.5% of calcium oxides, and 0.07 to 0.08% of tin from total amount of negative-plate active material. Proposed method for charging the cell includes charge with current amounting to 110% of its value at five-hour discharge, ratio of end voltages at extreme sub-zero and super-zero temperatures being 1.15. Cell is charged prior to placing it in operation at normal temperature for 5 h with current equal to 110% of its value at five-hour discharge, then with 55% of this current. n EFFECT: enhanced output capacity of cell and battery assembled of such cells at low ambient temperatures after pre-charge and discharge at low electrolyte temperature. n 4 cl |
