Abstract

A battery pack is provided that includes a case and at least one battery module disposed within the case. The battery pack further includes a flexible circuit to which the battery module may be electrically coupled. The flexible circuit includes a plurality of airflow openings configured to distribute air throughout the battery pack. In a preferred embodiment, the airflow openings vary in size relative to their proximity to an air source.

Claims

1. A battery pack, comprising:

a case;

a flexible circuit supported within said case;

a first battery module electrically connected to said flexible circuit; and

characterized in that said flexible circuit includes a plurality of airflow openings extending therethrough wherein a first airflow opening of said plurality of airflow opening differs in size from a second airflow opening of said plurality of airflow openings.

2. A battery pack, comprising:

a case;

a flexible circuit supported within said case;

a first battery module electrically connected to said flexible circuit; and

characterized in that said flexible circuit includes a plurality of airflow openings extending therethrough wherein the size of each one of the said plurality of airflow openings varies relative to a distance between said one airflow opening and an air source.
