Most lithium-ion battery pack designs
Most lithium-ion battery pack designs involving cylindrical, pouch or prismatic automotive cell. A typical battery pack case assembly includes a lower case in which the battery pack is accommodated, and a cover assembled to cover an upper surface of the lower case , and various structural reinforcing members (cross members, side members, etc.), and the battery pack together with a battery controller (Battery Management System, BMS) ) And related parts such as cooling blowers are mounted together. The weight reduction of the vehicle is a major challenge in the development of the electric vehicle, and thus, attempts to use the lightweight material for various parts of the electric vehicle are more important. The upper cover does not greatly support the load, it can be manufactured by a general plastic composite molding method, but for the lower case and the structural reinforcement In the case of members, steel parts are separately press-molded to withstand battery load or steel re...
