Claim Text:
1. A power source apparatus comprising: a plurality of batteries, wherein each of the batteries has a positive electrode terminal and a negative electrode terminal disposed separately on a same surface of the battery; a plurality of parallel blocks, each of the parallel blocks having a number of the batteries stacked together and electrically connected in parallel, wherein each of the parallel blocks has a set of the positive electrode terminals lined up at one side and a set of the negative electrode terminals lined up at the other side of a common surface formed by the surfaces of the batteries formed when the batteries are stacked into the parallel block as a single unit, wherein the parallel blocks are electrically connected in series to form a plurality of multiple parallel-series connected blocks, and the parallel blocks are stacked to form each of the multiple parallel-series connected blocks having an orientation with respect to a position of the positive electrode terminals and the negative electrode terminals; and a plurality of bus-bars including first bus-bars, second bus-bars, and third bus-bars, each of the first bus-bars and each of the third bus-bars having a plurality of insertion holes receiving the positive electrode terminals, and each of the second bus-bars and each of the third bus-bars having a plurality of insertion holes receiving the negative electrode terminals so that the batteries are electrically connected to each other, wherein each of the multiple parallel-series connected blocks has two parallel lines of the electrodes spaced apart from each other, and each of the lines of the electrodes is arranged alternately by the set of the positive electrode terminals and the set of the negative electrode terminals in the stacking direction of the batteries, wherein the bus bars extend in a stacking direction of the batteries along each of the two lines of the electrodes, wherein stacking directions of the batteries of at least two of the multiple parallel-series connected blocks are parallel to each other, the at least two of the multiple parallel-series connected blocks include at least one of the first bus-bars and at least one of the second bus-bars, respectively, wherein the at least one of the first bus-bars and the at least one of the second bus-bars are configured to connect to each other at a region where the parallel blocks overlap in a direction perpendicular to the stacking directions, wherein at least one of the third bus bars successively lies from the set of the positive electrode terminals to the set of the negative electrode terminals, which are arranged side by side, so that the at least one of the third bus bars electrically connects the batteries in the parallel block in parallel and simultaneously electrically connects the parallel blocks positioned side by side in series.
