ABSTRACT:
A method and apparatus for uniformly cooling or heating a plurality of test battery cells to a desired temperature having a housing with a first chamber and a second chamber separated by a bulkhead. A plurality of individual battery cell recepticles, such as sleeves, are mounted on the bulkhead. Each sleeve receives at least one battery cell and is sized to allow easy insertion and removal of the battery cell from the sleeve, helping to speed up testing. A uniform space is maintained between the battery cell inserted into the sleeve and the inner surface of the sleeve. A gas, such as air, is either cooled or heated, depending upon the desired temperature, and continuously circulated around the surface of the battery cell within the sleeve. The present invention enables a relatively large number of battery cells to be cooled or heated to a desired temperature and electrically tested quickly and with accurate results.
