Disclosed is a battery module improved in efficiency of resistance welding and bonding reliability. The battery module includes a plurality of secondary batteries, each having electrode terminals; a module housing having an inner space configured to accommodate the plurality of secondary batteries; and a bus bar including a body portion having a metal plate configured to electrically connect the plurality of secondary batteries to each other and a connection portion extending from the body portion to contact the electrode terminal. Each of the first connection portion, the second connection portion, and the third connection portion has at least one welding point.

Battery module having busbar, battery pack and vehicle

A battery pack is provided including at least one rechargeable secondary battery; a battery frame having a battery accommodation portion configured to accommodate the at least one secondary battery; a packaging member provided in the form of an adhesion sheet having an adhesive surface formed at one surface thereof, the packaging member including a body portion fixedly adhered to an upper portion of the secondary battery accommodated in the battery frame and a fixing portion bent and extended downward from the body portion and having the adhesive surface fixedly adhered to an outer surface of an outermost edge of the battery frame; and an anti-noise member attached to at least one portion of the adhesive surface of the packaging member.

Battery pack comprising battery frame

Disclosed is a serial-to-parallel converting apparatus. The serial-to-parallel converting apparatus includes: an input plate connected to positive electrodes and negative electrodes of a plurality of battery cells, respectively: an output plate spaced apart from the input plate and connected to an external terminal; a rotary plate rotatably interposed between the input plate and the output plate to electrically connect the input plate and the output plate, the rotary plate being configured to convert serial connection and parallel connection of the plurality of battery cells by rotating; and a case configured to accommodate the input plate, the output plate and the rotary plate.

Serial-to-parallel converter and battery module having same

Disclosed is a battery pack with enhanced cooling efficiency. The battery pack includes a plurality of battery cells respectively having electrode terminals formed thereon; a bus bar plate having a connection portion protrusively extending toward the electrode terminal to contact the electrode terminal to be electrically connected to the electrode terminal; and a heat dissipating member between the bus bar plate and the battery cell and having a connection hole into which the connection portion of the bus bar plate is inserted.
