Patent ID: 10629875

Abstract:
Disclosed is a battery module having a simple structure, facilitating reduction in weight and size, and saving manufacturing costs while securing an efficient cooling capability. The battery module includes: a plurality of pouch-type secondary batteries, each including an electrode assembly, an electrolyte, a pouch exterior, a receiving portion configured to receive the electrode assembly, and a sealing portion obtained by sealing the pouch exterior, wherein the plurality of secondary batteries are arranged in a left-and-right direction while standing in an up-and-down direction and each have a lower sealing portion that is folded; and a cooling plate including a thermally conductive material, arranged under the plurality of pouch-type secondary batteries while lying down in a horizontal direction, and having two or more protrusions to which lower portions of the secondary batteries are attached and a folding support portion located between the protrusions and protruding upwards, wherein the protrusions convexly protrude upwards from an upper surface of the cooling plate, and the folding support portion supports the folded lower sealing portion of each secondary battery upwards.
