This test is conducted to determine whether or not the modules and their cells are being maintained within their specified operating limits during maximum charge and discharge conditions of the EESA. During this test, it shall also be determined as to whether or not temperature sensitive safety critical components and temperature sensitive materials in the DUT are being maintained within their temperature ratings based upon the maximum operating temperature limits of the DUT. Temperatures on accessible surfaces, which may be contacted by the user, are also monitored.
