    Abstract: A battery pack includes: battery cells each including first and second end portions that are opposite each other in a length direction; a case providing an accommodation space in which each battery cell and a cooling fluid for cooling the battery cell are located, the case including a first cover covering the first end portion of the battery cell, the first cover including a first terminal hole through which the first end portion of the battery cell is partially exposed; and first and second sealing members doubly surrounding the first terminal hole from an outside of the first terminal hole to block a cooling fluid leakage passage formed through the first terminal hole. Therefore, while improving heat-dissipating performance, a cooling fluid sealing structure may be provided to the battery pack to prevent cooling fluid leakage from the accommodation space in which the battery cells are accommodated.

    Abstract: A battery pack includes: battery cells, each including first and second end portions that are opposite each other in a length direction; a case having an accommodation space in which the battery cells and a fluid to cool the battery cells are configured to be accommodated, the case including first and second covers respectively covering the first and second end portions; first and second tab plates respectively on the first and second covers and connected to the first and second end portions; a circuit board on the first tab plate; and a first lead and a second lead through which the first and second tab plates are connected to the circuit board, the first and second leads connected to a first side portion of the circuit board. An arrangement of the leads connected to electrodes of the battery cells is improved, and heat is efficiently dissipated from a switch device.

    Abstract: A battery pack includes: a plurality of battery cells; a case providing an accommodation space for accommodating the battery cells and a cooling fluid for cooling the battery cells; and a barrier wall extending across the accommodation space and dividing the accommodation space into an upstream area in communication with an inlet for the cooling fluid and a downstream area in communication with an outlet for the cooling fluid. The barrier wall provides a communication area where the upstream area and the downstream area communicate with each other. The inlet and the outlet are at a first end of the barrier wall in an extension direction of the barrier wall, and the communication area is at a second end of the barrier wall in the extension direction of the barrier wall.

    Abstract: One aspect is a battery pack for a transportation device, the battery pack including a plurality of bare cells and a case including a bottom portion including an air guide pipe. The case has a sidewall portion extending from the bottom portion so as to form a space accommodating the bare cells, the sidewall portion having an air hole passing therethrough. The air guide pipe is configured to transfer air received from the environment to the interior of the case via the air hole.
