A battery module includes: a plurality of cylindrical battery cells including a gas vent portion to discharge an internal gas; and a busbar plate including a plurality of connection terminals that protrude and extend from an inner edge of a connection opening, and to electrically connect the cylindrical battery cells by contacting a positive or negative electrode terminal, and have different shapes depending on the contacted positive or negative electrode terminal, and a connection terminal contacting a positive or negative electrode terminal not having the gas vent portion. The connection terminal includes: a fuse portion to be disconnected when a current of a predetermined level or higher flows from the cylindrical battery cells and having a bent structure bent; and a protection tube to contract at a predetermined temperature with electric insulation and to surround at least a portion of an outer surface of the fuse portion.

Battery module comprising busbar plate, battery pack comprising battery module, and electronic device

A battery module according to the present disclosure includes a plurality of cylindrical battery cells including a gas vent configured to discharge an internal gas and a busbar plate including a negative electrode connection terminal extending from an edge of a connection opening and having the extended part in contact with a negative electrode terminal to electrically connect the plurality of cylindrical battery cells wherein among a positive electrode connection terminal and the negative electrode connection terminal, the connection terminal in contact with a positive electrode terminal or a negative electrode terminal that is not opened by the gas vent includes a fuse portion configured to blow when a predetermined current or above flows from the cylindrical battery cell, the fuse portion having a bent structure that is bent in a horizontal direction at least once.

Battery module comprising bus bar plate, battery pack comprising same, and electronic device

The present disclosure relates to an apparatus and method for diagnosing a state of a battery pack, and more particularly, to an apparatus and method for diagnosing a state of a battery pack based on a SOC of a battery module included in the battery pack. According to the present disclosure, since the SOC of the battery module corresponding to an induced abnormal situation is estimated and the state of each battery module is diagnosed based on the estimated SOC, a risk factor that may occur in the battery module may be diagnosed in advance.

Apparatus and method for diagnosing state of battery pack

Discussed is a pressing apparatus for pressing a plurality of battery cells, the pressing apparatus including a pressing jig including a support plate, and a plurality of pressing rods respectively disposed on a first side of the support plate and located to respectively face the plurality of battery cells, the plurality of pressing rods being configured to respectively press the plurality of battery cells and to adjust to sonic of the plurality of battery cells that are not level during pressing; and a transfer unit disposed on a second side of the support plate and having a transfer jig configured to transfer the support plate towards the plurality of battery cells.

Pressure device, battery module manufacturing device, and manufacturing method

Disclosed is a battery module. The battery module includes at least one battery cell, a casing configured to surround the battery cell and having at least one opening formed therein; and a thermal interface material (TIM) interposed between the casing and the battery cell and exposed out of the casing through the opening of the casing.

Battery module and battery pack including the same

An apparatus and method for preventing overcharge of a secondary battery that prevents the overcharge of a Starting Lighting Ignition (SLI) battery, which can be applied to both a regulated system with a voltage regulator and an unregulated system without a voltage regulator, by regulating the voltage applied to the cell assembly.
