Abstract:
A sealed secondary battery assembly, comprising:electricity-generating elements;battery cell cases formed as rectangular tubes having a bottom, opposing partition walls and opposing side walls defining a cell case aperture, said electricity-generating elements being disposed respectively in said battery cell cases;battery cell case covers sealing said cell case apertures to form a plurality of sealed battery cells, said cell case covers being formed contiguous as a unitary cover;said battery cell cases being disposed serially adjacent one another and said partition walls having partition wall surfaces with contacting portions contacting adjacent ones of said partition walls, said contacting portions being fixed together to form a unitary battery case, said partition walls thereby forming partition sections of said unitary battery case which partition said sealed battery cells from one another;electrical connection elements passing through said partition sections, formed by the partition walls, to serially connect said electricity-generating elements without use of electrical connection members extending through said battery cell case covers; andsaid partition walls defining coolant passages in said partition sections.
