美国能源部：锂电池电热分析报告

One of the goals of DOE/FreedomCAR program is to develop high-power, safe, long-lasting and affordable batteries for various hybrid vehicle applications, including the 42V mild hybrids.
•
With cost sharing from DOE/FreedomCAR, United State Advanced Battery Consortium (USABC) contracted Saft to develop a high-power, low-cost battery to meet the FreedomCAR technical targets for 42V M-HEV batteries (2003-2005).
•
With support from DOE, NREL performed thermal analysis and testing for understanding and, if needed, improving thermal performance of cells supplied by the USABC program.
Temperature greatly affects the performance and life (and thus warranty costs) of batteries.
•
Battery thermal control/management is a must for hybrid electric vehicles under real driving conditions.
•
Good battery pack thermal management starts with cells and modules that perform well thermally.
•
Thermal modeling and simulation could aid in designing batteries with better thermal behavior.
•
A 3-D model capturing electrical, as well as thermal behavior of batteries with real geometries and details including the non-electrochemical parts, was needed.
