Document Type and Number:
WIPO Patent Application WO/2021/108986
Kind Code:
A1
Abstract:
A battery module (20), a battery pack (10), a device, and a manufacturing method for the battery module (20). The battery module (20) comprises: a battery unit (21) having a first total output electrode (21a) and a second total output electrode (21b) and comprising more than two battery assemblies (21c) disposed side by side and mutually connected in series, each battery assembly (21c) comprising at least one secondary battery (22), two post terminals (222) of each secondary battery (22) being arranged to form two columns of post terminal groups, and an accommodating gap (22a) existing between the two columns of post terminal groups; a first output electrode sheet (30) comprising a first connection portion (31), an intermediate connection portion (32), and a first output portion (33) which are connected to the first total output electrode (21a), the intermediate connection portion (32) being connected to the side of the first connection portion (31) close to the accommodating gap (22a); and a second output electrode sheet (40) comprising a second connection portion (41) and a second output portion (42) which are connected to the second total output electrode (21b), the second total output electrode (21b) being located on the side of the first total output electrode (21a) close to the second output portion (42); the first output portion (33) and the second output portion (42) being disposed on the same side of the battery unit (21). The battery module (20) can reduce the complexity and space occupancy rate of connection wire harness arrangement.
