FIELD: electricity. ^ SUBSTANCE: connecting device for external connection of battery cells includes, at least, one connecting element from graphite mixture designed for electric consecutive or parallel connection of two battery cells. In order the connection of battery cells had high electrical conductivity without the application of traditional welding technologies the connecting element from graphite mixture is in close contact with nickel or nickel-plated outputs of battery cells. Connecting element from graphite mixture has lower cost and oxidisability; note that close contact of connecting element from graphite mixture with nickel-plated metallic outputs of positive and negative battery cells leads to their relative dissolution with formation of solid solution containing nickel and carbon, note that due to resistance decrease of external connection a gradual discharge at heavy currents is provided. ^ EFFECT: decrease of coast and resistance losses. ^ 5 cl, 8 dwg |
