Abstract: Discussed is a battery that may include at least one battery module including at least one battery cell, a case tray configured to support the at least one battery module, a case cover coupled with the case tray to cover the at least one battery module, a sealing gasket disposed between the case tray and the case cover to prevent penetration of moisture or foreign substance into the at least one battery module, and a reinforcing unit provided to the case cover to be disposed adjacent to the sealing gasket and configured to prevent twisting of the case cover when the case tray and the case cover are coupled.

Abstract: Discussed is a battery pack that may include at least one battery module including at least one battery cell; a case tray configured to support the at least one battery module; a tray cover coupled to the case tray; and at least one bushing gasket configured to connect the case tray and the tray cover and to support the case tray on a plurality of points.

Abstract: A battery pack assembly guide jig for guiding an assembly of a battery pack having a case tray and a case cover is provided. The battery pack assembly jig includes a first guide configured to temporarily fix a first side edge of the case tray and a first side edge of the case cover, and a second guide spaced apart from the first guide by a predetermined distance and configured to temporarily fix a second side edge of the case tray opposite the first side edge of the case tray and a second side edge of the case cover opposite the first side edge of the case cover. The battery pack assembly guide jig is configured to support the case tray and the case cover of the battery pack when the case tray and the case cover are coupled to each other.

Abstract: A coolant port assembly includes a coolant port including a port portion having a pipe shape formed to extend by a predetermined length, and a plate-shaped mounting bracket portion formed at one side of an outer circumference of the port portion to expand in a direction intersecting a longitudinal direction of the port portion; a sealing gasket provided in a ring shape that surrounds a peripheral outer side of the port portion; and a gasket cover configured to be closely coupled to the mounting bracket portion together with the sealing gasket while pressing a part of the sealing gasket.

Abstract: A battery module, a battery pack including the same, and a vehicle including the same are provided. The battery module includes a stack of battery cells; a cover accommodating the stack of battery cells; and a bus bar electrically connecting the battery cells; a relay comprising a connection terminal coupled to the bus bar; and a joint block coupled to the bus bar and the connection terminal of the relay.

Abstract: A battery pack has improved safety against external impacts, and an energy storage system and a vehicle including the same. The battery pack includes a battery module having at least one battery cell; a tray having a plate shape so that the battery module is mounted thereon; a reinforcing member having a plate shape and mounted on the tray, the reinforcing member having at least a portion coupled to the tray and the other portion supporting the battery module upward, the reinforcing member being configured to form a space separated from the tray below the other portion supporting the battery module; and an elastic member constrained in the separated space in an elastically deformed state and configured to press a lower surface of the reinforcing member upward.

Abstract: A battery pack having at least one battery module including at least one battery cell, a case tray configured to support the at least one battery module, a case cover coupled to the case tray such that the at least one battery module is located between the case tray and the case cover, and a sealing gasket disposed between the case tray and the case cover to prevent penetration of moisture or foreign substances into the battery module is provided. The sealing gasket includes at least one position guide configured to guide positioning of the sealing gasket between the case tray and the case cover when the case tray and the case cover are coupled to each other.
