When the current flows from the battery bank to a driving motor, the cells composing the battery have a chemical reaction heat. And then, the heat is conducted to the current-collection-tabs connected with the battery. It is considered that the sheet metal is connected with the tab as one of the solutions in order to maintain the ability of the power supply. Magnetic pulse welding is effective for lap-joining similar and dissimilar sheet metals such as Al/Al, Cu/Cu and Cu/Al. In this study, a voltage drop of the juncture of the sheets obtained by this welding method was measured 1000 times automatically by botha crossed rod method and a four-wire terminal method, and an electric joining resistance of the juncture was estimated by an average value of the voltage drop. The joining resistances, Al/Al and Cu/Cu, were less than 5 μΩ both. Therefore, the joule exothermic reaction of the juncture by the passage of the large current is small, and the absorption of the heat which arises in the battery can be expected.}, pages = {82--86}, title = {圧接試験片における接合部電気抵抗の基礎的測定}, volume = {7}, year = {2013}, yomi = {カバサワ, エイキ and イシバシ, マサキ and オカガワ, ケイゴ} }
