A sheet metal assembly includes a drawn metal sheet constructed of a metal material. The drawn metal sheet defines a surface and includes one or more stiffening features disposed along the drawn metal sheet. The one or more stiffening features represents a raised area disposed along the surface of the drawn metal sheet. Each of the one or more stiffening features include a predefined draw depth ranging from about twenty millimeters to about eighty millimeters.

A battery pack includes a base plate forming a bottom surface; a main frame combined to the base plate and extending in a height direction to form a wall structure for supporting both side portions of the plurality of battery modules; and a top plate combined to an upper portion of the main frame to form a ceiling, wherein at least one of the top plate and the base plate is provided in a plate body shape including a bead.

A battery for a motor vehicle includes at least one cell assembly with a large number of battery cells, wherein the battery cells each have a cell housing with a degassing element for discharging a hot gas produced in the cell housing in the event of a fault, a battery housing with housing walls which enclose a receiving space for receiving the at least one cell assembly, and a deactivation device which is arranged in the receiving space of the battery housing and has at least one sleeve which is filled with a combustion-promoting agent, wherein the sleeve, when it is acted on by the hot gas discharged from at least one battery cell, is configured to release the combustion-promoting agent.

A battery module comprises: battery cells which are arranged in one direction and electrically connected to each other via bus bars and each of which has a positive terminal and a negative terminal; a cover member which includes a front cover disposed on the front surface of the battery cells, a rear cover disposed on the rear surface of the battery cells, an upper cover for covering the upper surface of the battery cells, and a lower cover for covering the lower surface of the battery cells; a pair of connection parts which are electrically connected to the bus bars and disposed to be positioned on the rear cover side so as to be electrically connected to the outside; and an insulation cover which is disposed between the upper cover and the upper surface of the battery cells to block physical contact between the bus bars.
