Title:
Battery pack
Document Type and Number:
Japanese Patent JP6198401
Kind Code:
B2
Abstract:
Battery pack capable of improving the safety thereof. The battery pack includes a battery array, side plates, a top cover and end plates. The battery array includes a plurality of battery cells aligned in a first direction. The battery array is formed as a hexahedron having (1-1)th, (1-2)th, (2-1)th (2-2)th, (3-1)th and (3-2)th planes. The top cover is provided to the (1-1)th plane of the battery array, and has reinforcing frames respectively formed at both sides based on the first direction. The reinforcing frame includes vertical and horizontal frames, and the longitudinal section of the reinforcing frame is formed in an 'L' shape. The end plates are provided to the (3-1)th and (3-2)th planes, respectively. The end plates are fixed to the top cover. The side plates are provided to the (2-1)th and (2-2)th planes, respectively. A holding part pressing both sides of the top cover on the (1-1)th plane are provided to the side plates, respectively. At least one first weight-saving hole may be formed in the side plate. Accordingly, the structural safety of the battery pack is improved by preventing the warping of the battery pack, and the cooling efficiency is increased by improving the contact pressure between the battery pack and the cooling member. Further, the lifetime of the battery pack is increased by equalizing the cooling efficiency of the battery cells.
