Abstract

We developed a high power battery pack module composed of 18650-type high-power lithium-ion batteries. The newly designed unit cell drives a maximum constant 6C-rate discharge current. The cell retains the same level of safety as the conventional type. We also developed a cycle simulation method to design a pack module for high power discharge. It predicts the cyclic behavior of the battery pack module derived from the properties of individual cells. It also makes it possible to determine the permissible range of unit cell capacity and impedance to compose high power battery pack modules.
