Abstract
Official abstract text for this publication.
A manufacturing method of a battery pack includes a restraining process of restraining single cells at a maximum restraint contact pressure Pd of the battery pack in a complete state, after compressing the single cells at a maximum compression contact pressure Pc that satisfies 0.8≦Pd/Pc≦0.9, with respect to the maximum restraint contact pressure Pd; a standing process of then leaving the single cells to stand for a predetermined number of days in an electrically open state; and a short-circuit testing process of then testing for an internal short in the single cells.
First claim
Opening claim text (preview).
What is claimed is: 1. A manufacturing method of a battery pack that includes a plurality of single cells, each of which has an electrode body that includes an electrode plate and a separator, and a restraining member that restrains the single cells, the manufacturing method comprising: a restraining process of restraining the single cells in a thickness direction of the electrode plate and the separator at a maximum restraint contact pressure Pd, after compressing the single cell…
