This manual defines a series of tests to characterize aspects of the performance or life behavior of ultracapacitors for hybrid electric vehicle (HEV) applications.a Tests are defined based on the general approach used for all FreedomCAR energy storage testing; however, it is anticipated that these tests may be generally useful for testing capacitors for hybrid electric vehicle or other uses. Most tests are considered applicable to cells, modules, or complete capacitor energy storage systems. This manual does not include special tests for characterizing system behavior, because these are necessarily application-oriented.
