DOE/ID-11069

This manual defines a series of tests to characterize aspects of the performance or cycle life behavior of batteries for hybrid electric vehicle applications. Tests are defined based on the FreedomCAR program goals for power-assist hybrid electric vehicles, though it is anticipated these tests may be generally useful for testing energy storage devices for hybrid vehicles. The test procedures in this manual are directly applicable to complete battery systems. However, most can also be applied with appropriate scaling to the testing of cells, modules or less-than-full-size batteries. Much of the rationale for the test procedures and analytical methodologies utilized in this manual evolved from the former PNGV Battery Test Manual (Reference 2).
