Abstract
The present invention provides a battery block that accommodates unit cells having higher capacities, and, even in case of abnormal heat generation in the unit cell, does not cause abnormal heat generation in the neighboring unit cells, thereby preventing a chain reaction of degradations and abnormalities of the accommodated unit cells. The battery block of the present invention includes a battery case having a minimum thickness section satisfying the relationship “K2/K1≧K3−1”. K1 is the thermal conductance between the battery case and the unit cell. K2 is the thermal conductance of the minimum thickness section of the battery case between two neighboring holes for accommodating the respective unit cells. K3 is a ratio between the abnormal heat temperature of a reference cell and the ambient temperature causing abnormal heat generation in this cell.
