Abstract
Recently, the demand of high power lithium-ion batteries has become higher. If lithium-ion batteries are used in high power application, the battery capacity degradation due to heat generated from inside of the batteries becomes a problem. Therefore, we have studied about cooling structure of lithium-ion battery modules to increase the power of lithium-ion batteries. The lithium-ion Battery module that we developed has two important points. Firstly, we applied the aluminum die-casting case having flow paths as a module case. Secondly, we applied the thermally conductive compound. The results of the experiment, we verified that the battery module can be used in the 6C(C-Rate) charge-discharge cycle.
