Electrical Performances of High Power Electric Double Layer Capacitor under Thermal and Mechanical Stress

摘要

Electric double layer capacitors are recently proposed for various automotive applications. For speeding up the penetration in the market of this technology, reliable data about the devices’ performances in every condition are needed. In particular severe mechanical and thermal stresses, which are normal on vehicles, should be deeply investigated. But being relative new devices there are not yet consolidate procedures. In literature for the mechanical stress only abuse test procedures are present. The paper tries to cover this lack giving a procedure to analyze the electric double layer performance while a mechanical stress is taking place. Besides, part of the preliminary laboratory results are shown.
