Abstract
A thermal design for lithium-ion battery packs with the world's highest volumetric energy density for use in power storage systems is described. The 130L battery pack's maximum load conditions during charging and discharging were obtained by a histogram analysis of our wind turbine system. We fabricated long, thin battery modules for natural convection cooling by laminated battery cells. As a result of our designed clearance ratio between modules and the setting of slanted airflow guides between modules, we achieved target temperature rises of less than 15K.
