The present disclosure relates to an apparatus and method for evaluating durability of a battery module frame for a vehicle. According to the present disclosure, it is possible to easily evaluate the durability or a similar quality of the welded portion of the battery module frame by providing constraints similar to a situation in which a swelling phenomenon occurs in a battery cell in the battery module frame.

Apparatus and method for evaluating durability of battery module frame for vehicle

A battery pack has a movable busbar assembly and a secondary battery including the same. More particularly, a battery pack has a movable busbar assembly configured such that at least one of a first busbar frame located at the front surface of a pack case, a second busbar frame located at the rear surface of the pack case, a first busbar connected to the first busbar frame, and a second busbar connected to the second busbar frame is movable in a direction toward a side plate of the pack case, whereby it is possible to minimize short circuit between leads, and a secondary battery including the same.

The present invention relates to a battery module simulation system and method for easily implementing pressure and temperature conditions in a battery module by easily changing the pressure and temperature applied to a battery cell in a pressure measurement test of the battery cell.

Battery module simulation system and method

Disclosed is a 3-D printing apparatus. The apparatus includes an ink output module including an ink supply unit having an ink for forming an electrode portion, electrolyte or packaging portion received therein and an ink discharge unit coupled to the ink supply unit; a driving unit having the ink output module mounted thereon to move the ink output module in an X, Y, Z axis direction with respect to a substrate where a supercapacitor or secondary battery will be formed; a dispenser connected to the ink supply unit to supply gas having controlled pressure to the ink supply unit through a gas supply tube and to supply the ink within the ink supply unit through the ink discharge unit; and a controller controlling the output of the ink by transmitting a control command for fabricating the supercapacitor or the secondary battery to the dispenser and the driving unit.
