Characteristics and development report for the MC4169 double-layer capacitor assembly

Abstract

The MC4169 Double-Layer Capacitor Assembly was developed in response to a request from the B61 Systems organization to provide interim power for the B61 Common JTA Development. The project has been successfully completed, and Lot 1 has been built by MMSC/GEND. Development testing showed that this assembly met all design requirements. This report describes the design configuration, environmental testing, and aging, reliability, and safety studies done to ensure that the design requirements were met.

Current status of environmental, health, and safety issues of electrochemical capacitors for advanced vehicle applications

“…The high-g shock tests found momentary voltage loss, but no hazard was associated with this test (Clark and Baca 1993). In advanced vehicles, high-g shock could occur, so additional high-g shock tests on actual devices for that application will be needed to verify that no hazardous conditions occur.…”

“…Sandia National Laboratories conducted vibration and high-g shock tests on electrochemical capacitors. Although performance of single cells was not affected by the vibration test, performance of assemblies of the tested prototype cells was reduced (Clark and Baca 1993). An improved cell design eliminated this problem, which was apparently caused by a faulty adhesive (Clark 1996).…”

“…One of the tests was an aging test, which did not reveal safety hazards. Other tests included vibration and high g-force shock, which will be discussed in the Mechanical Hazards section (Clark and Baca 1993).…”
