ABSTRACT:
In constructing assembled batteries by electrically connecting through a connecting bar the terminals of neighboring single cells by means of metallic parts of the terminals, by directly covering both sides of the connecting bar with the exception of the electrical connection with an insulating protecting layer of either natural rubber, synthetic rubber, or synthetic resin, and by directly or indirectly insulating and protecting the surface of the metallic parts for electrical connection, it was made possible to prevent corrosion of the connecting bar and the metallic parts for electrical connection, and to prevent capacity fluctuation due to heretofore observed leakage current of single cells composing electric vehicle batteries to be used under severe conditions for a long period and at a high operating voltage, thereby improving the reliability and dramatically reducing the maintenance load.
