A battery pack according to an exemplary embodiment of the present invention includes: multiple unit batteries which are positioned in parallel in a first direction; and a pair of connecting members which is attached to both sides of the multiple unit batteries and electrically and physically connects the multiple unit batteries in the first direction. Each of the pair of connecting members includes: multiple battery fixing portions which are attached to the multiple unit batteries, respectively; and at least one deformable portion which is positioned between the multiple battery fixing portions such that at least a part of the deformable portion is in a non-contact state with the multiple unit batteries and the deformable portion is bent by external force.

Battery pack

An embodiment of the present invention provides a battery pack comprising a plurality of battery cells; a protective circuit module coupled to at least two battery cells; and a case accommodating the battery cells and the protective circuit module, wherein the two battery cells are disposed on a surface of the case, and the protective circuit module is disposed between the two battery cells on the surface of the case.

A protection apparatus that is disposed adjacent a first side of a bare cell of a battery having at least one electrode. The protection apparatus comprises a first and a second lead plates that are adapted to be connected to the at least one electrode of the bare cell and a pad unit comprising a plurality of conductive pads that are adapted so that external devices are coupled to the battery via the conductive pads of the pad unit. The protection apparatus also comprises a device unit that includes electrical components that provide protection to the bare cell of the battery; wiring that interconnects the first and second lead plates, the pad unit and the device unit; and an insulator that encapsulates at least a portion of the first and second lead plates, the pad unit, the device unit and the wiring.

Protection apparatus of battery pack, method of manufacturing the protection apparatus, and battery pack including the protection apparatus

The present invention relates to a secondary battery. The present invention is aimed to provide a secondary battery having a thin upper case formed of a metal. The secondary battery includes a bare cell; a protection circuit module having a circuit board; an upper case formed of a metal and having a cover plate for covering the circuit board of the protection circuit module; and a case-insulating layer formed on an external surface of the cover plate of the upper case.

Secondary battery

A protective circuit module for a secondary battery is provided including a circuit board. At least one protection control circuit element for preventing overcharge and over-discharge of the secondary battery is mounted on the circuit board. A first conductive pad is coupled to the circuit board. A positive temperature coefficient device is between the at least one protection control circuit and the first conductive pad such that when a secondary battery temperature reaches a threshold value, resistance of the positive temperature coefficient device is increased and battery current is reduced.

Protective circuit module for secondary battery and battery pack using the same

The present invention relates to a battery pack including a bare cell for charge/discharge of an electric current; a protection circuit board electrically connected to the bare cell and protecting the bare cell against overcharge/discharge thereof; a connector serving as a current path between the bare cell and an external apparatus; a cover frame disposed on the bare cell to cover the protection circuit board; and a connector housing where the connector is disposed and which is exposed to the outside of the cover frame. The assembly strength of the battery pack is improved due to solid mounting of the connector housing on the protection circuit board and non-separable connection of the connector housing and the cover frame.

A rechargeable battery pack configured to prevent a frame from being damaged due to external impact forces while insulating a protection circuit module from short circuit is described. In an exemplary embodiment, the rechargeable battery pack may include a plurality of unit cells made up of a rechargeable battery connected to a frame which accommodates and supports the unit cells and having a loading portion sandwiched between the unit cells. The rechargeable battery pack may further comprise an electrically insulating holder connected to a loading portion, and a protection circuit module electrically connected to the unit cells and installed into the holder.

Rechargeable battery pack

The present invention relates to a connector assembly and a battery pack having the same. For this purpose, provided are a connector assembly with optimized size and mounting area of the connector assembly serving as a current-carrying medium of the battery pack, and improved bond strength between the connector terminal and the housing, and a battery pack having the same.

Connector assembly and battery pack having the same

Disclosed is a card type battery that has both functions of a smart card and a battery. The card battery can prevent a short caused by contact with an external device, reduce a total thickness of the battery and improve bonding strength between internal elements of the battery.

A rechargeable battery pack may be used with a protection circuit module in common for serial or parallel connection of unit cells. The rechargeable battery pack may include a plurality of unit cells for forming a rechargeable battery by providing an electrode assembly to a pouch, a protection circuit module electrically connected to the unit cells, and a connector connected to the protection circuit module. The protection circuit module may include a serial protection circuit for electrically connecting the unit cells in series and a parallel protection circuit for electrically connecting the unit cells in parallel.

A battery pack is disclosed. An embodiment of the battery pack includes a bare cell, wherein the bare cell comprises a terminal; a circuit module coupled with the bare cell, wherein the circuit module comprises a protective device; and a cover disposed over the circuit module and coupled with the bare cell; wherein the circuit module comprises a through-hole, the cover comprises a protrusion, the protrusion engages with the through-hole, and the through-hole enables welding of the protective device of the circuit module to the terminal of the bare cell through the through-hole.

A battery pack including an external case having improved strength to protect a bare cell is provided. The battery pack includes a bare cell, a cover plate attached to one of long side surfaces that are widest planes of the bare cell, and an external case including a resin portion and a reinforcement plate and accommodating both the bare cell and the cover plate, wherein the resin portion surrounds sides of the reinforcement plate.

In a rechargeable battery, a case is combined with an upper surface of a bare cell by being fixed to a lead plate electrically coupling a protection circuit board of a protection circuit module to the bare cell. Alternatively, the case is combined with the bare cell by being fixed to the protection circuit board so as not to be separated from the bare cell, thereby improving the reliability of the products.

Rechargeable battery

A battery pack to improve assembling reliability in a battery with a cover frame. The battery pack according to the present invention includes a rechargeable battery having at least one rounded lateral side; a cover frame including a frame surrounding each of lateral sides of the rechargeable battery, wherein more than at least one groove is formed at both ends of the frame covering the rounded lateral side of the rechargeable battery. Therefore, it is possible to couple the cover frame to the rechargeable battery via the groove without deforming the cover frame. Also, the rounded battery and the rounded cover frame closing each other is an effect that assembly error of a battery to cover frame can be reduced.

Battery pack having a cover with at least one cut portion formed therein
