According to some embodiments, a process for manufacturing the battery module is simplified and material costs are reduced.

Battery module

Provided is a battery pack. The battery pack includes: a case including a cavity; a core pack that inserts into the cavity and comprising a plurality of batteries; a first cover coupled to a side of the case; and a second cover coupled to the other side of the case. The case further includes a plurality of guide grooves formed in inner corners of the case and extending in a length direction of the case, and the core pack further includes a plurality of ridges that respectively slide into the guide grooves in the length direction of the case.

Provided is an food packing material, manufacturing method. A battery pack and a electrical bike having the same are further provided. In particular, the battery pack may include a battery pack, battery array, a protecting circuit module, and a connection terminal section. The battery case may be formed as cylindrical or polygon. The battery array may include a plurality of batteries formed as multi-stage within the battery pack. The protecting circuit module may be provided between an upper portion of the battery array and an upper surface of the battery pack. A connection terminal portion may be formed at the lower stage of the battery pack and may include a power terminal and a control terminal. By providing the battery pack as bottle shape, the electrical bike can selectively accommodate the bottle for the bike and the battery pack.

Battery pack and electric bike having the same

A battery pack is disclosed. One aspect includes a battery pack module having a housing and a plurality of battery packs, each pack housing a case in which a plurality of batteries are received, an electrode tab to connect the batteries to form one unit, and a data wire having a first end connected to the electrode tab, to act as a signal transmitting line of the plurality of batteries.

A rechargeable battery pack includes a rechargeable battery cell, and a pair of cell holders receiving respective sides of the rechargeable battery cell in a length direction, the pair of cell holders being combinable with each other. Each of the cell holders includes a base that supports the rechargeable battery cell, a combination protrusion and a combination groove symmetrically disposed on an outer side of the base, a protrusion protruding from the base in the length direction so as to be combinable in the length direction, and a recess portion being concave in the base in the length direction such that the recess portion of one of the pair of cell holders is combinable with the protrusion of the other of the pair of cell holders.

Rechargeable battery pack

A secondary battery has charging and discharging functions. The second battery prevents an external connection portion from being separated from a connection terminal due to external shocks.

Secondary battery
