Abstract
An integrated sealed secondary battery in which a plurality of cells are arranged in a row, cooling medium passages are formed on both sides on the row of the cell, and cooling medium passages are formed between adjacent cells such as to effect communication between the cooling medium passages on both sides.
Claims16
An integrated sealed secondary battery comprising:
- a plurality of cells, having an outside, arranged in a row respectively accommodating electricity-generating elements,
- said row having two ends,
- each cell having a rectangular tubular case with a bottom end, an upper end, a first side, a second side, a third side and a fourth side;
- cooling jacket members forming first cooling medium passages along the first and second sides of the cells adjacent the cooling jacket members;
- second cooling medium passages formed between the tubular cases on the third side and on the fourth side of respective cells and communicating with the first cooling medium passages;
- said third side and said fourth side of respective cells including bosses;
- and
- said second cooling medium passages being formed by the bosses being mutually welded to respective opposing ones of the bosses.
