1. A battery system comprising:
- a battery block that includes a plurality of rectangular batteries that have a width greater than their thickness and that are arranged in alignment in an array by a battery holder;
a coolant pipe that cools said rectangular batteries of said battery block; and
a coolant feeding device that feeds coolant to circulate through said cooling pipe;
wherein said cooling pipe is arranged on a surface of said battery block in a thermally-coupled state so that said rectangular batteries are cooled by the coolant which is circulated through said cooling pipe;
wherein said battery block has end parts and a middle part between said end parts on said surface, said coolant pipe extending along said surface through one of said end parts, through said middle part and through the other of said end parts;
wherein said cooling pipe has a plurality of parallel piping portions that are arranged in parallel to said rectangular batteries and cool said rectangular batteries, including first said parallel piping portions at said middle part, second said parallel piping portions at the one of said end parts and third said parallel piping portions at the other of said end parts; and
wherein each of said parallel piping portions of said cooling pipe are parallel with each other and said parallel piping portions are spaced from adjacent ones said parallel piping portions by gaps that are different in width for the first said parallel piping portions at said middle part of said battery block than for the second and third said parallel piping portions at said end parts of said battery block.

Abstract
A battery system includes a battery block, a cooling pipe, and a coolant feeding device. The battery block includes a plurality of rectangular batteries that have a width greater than a thickness and are securely arranged in array alignment by a battery holder. The cooling pipe cools the rectangular batteries of the battery block. The coolant feeding device feeds coolant to the cooling pipe. In the battery system, the cooling pipe is arranged on the surface of the battery block in a thermally-coupled state so that the rectangular batteries are cooled by the coolant, which is circulated through the cooling pipe.
