8. A method for testing connections in a battery module containing a plurality of batteries and a bus bar for connecting battery electrodes of said plurality of batteries electrically in parallel, the method comprising:
-
contacting a first contact pin of a resistance measurer with an electrode of one of the plurality of batteries contained within the battery module; contacting a second contact pin of the resistance measurer with a point on a conductor arrangement, wherein said conductor arrangement includes the bus bar, the electrode of another of the plurality of batteries, optionally, a connector element extending between said bus bar and the electrode contacted by the first pin, and optionally, a connector element extending between said bus bar and the electrode of another of the plurality of batteries; and measuring electrical resistance between said first contact pin and said second contact pin using the resistance measurer. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
