Method and device for testing the connections of batteries
First Claim
1. A method for testing a quality of electrical connections in a battery module containing a plurality of batteries and a bus bar for connecting electrodes of said plurality of batteries electrically in parallel, wherein the bus bar is a planar plate provided with a plurality of through holes, wherein each battery contained in the battery module has one electrode arranged on each opposing end of the battery, and wherein each battery has one electrode arranged under one of the plurality of through holes provided in the bus bar, said method comprising:
- extending a first contact pin of a resistance measurer through one of said through holes in the bus bar such that the first contact pin makes contact with an electrode of one of said plurality of batteries contained within said battery module;
contacting a second contact pin of said resistance measurer with a point on a conductor arrangement, wherein said conductor arrangement includes said bus bar,an electrode of another of said plurality of batteries contained in said battery module,optionally, a connector element extending between said bus bar and said electrode contacted by said first contact pin, andoptionally, a connector element extending between said bus bar and said electrode of another of said plurality of batteries contained in said battery module; and
measuring electrical resistance between said first contact pin and said second contact pin using said resistance measurer to determine the quality of electrical connections between said electrode contacted by said first contact pin and said point on said conductor arrangement contacted by said second contact pin.
