1. INTRODUCTION
This manual has been prepared to guide battery developers in their effort to successfully commercialize advanced batteries for automotive applications. The manual includes criteria for design of a battery life test matrix, specific life test procedures, and requirements for test data analysis and reporting. Several appendices are provided to document the bases for the procedures specified in the manual. Previous battery life test procedures published in FreedomCAR battery test manuals (References 8 through 11) are superceded by this present Technology Life Verification Test (TLVT) manual.
This introduction presents the FreedomCAR battery life goals and life verification objectives, along with the general approaches for life test matrix design, reference performance testing, and life test data analysis. Organization of the manual is then summarized.
1.1 FreedomCAR Battery Life Goals
FreedomCAR battery life goals for two representative power-assist hybrid-electric vehicle (HEV) applications are presented in Table 1 of Reference 8. The calendar life goals are the same for all automotive applications—15 years in service. The cycle life goals depend on the powerassist ratings—240,000 cycles at 60% of rated power, plus 45,000 cycles at 80% of rated power, plus 15,000 cycles at 95% of rated power. A cycle consists of a power profile that includes the vehicle operations of engine-off, launch, cruise, and regenerative braking. This set of three operating conditions corresponds to the 90th percentile of automotive customer requirements. Similar requirements have been specified by FreedomCAR for 42-volt applications (Reference 9), fuel cell powered vehicles (Reference 10) and ultracapacitors (Reference 11).
