Abstract: A vehicle battery pack comprises an upper cover, a tray, and a battery cell located within a space defined collectively by the upper cover and the tray. The battery cell has a first side surface provided with a cell exhaust vent or facing the cell exhaust vent. The upper cover, the tray, or both comprises a first side portion adjacent to a second side surface of the battery cell. The first side surface is adjacent to the second side surface. The first side portion is provided with a first ventilation channel for collecting exhaust gas from the battery cell. At least a portion of the first ventilation channel is isolated from the battery cell.

Abstract: The present disclosure provides a battery pack, comprising: a first battery cell; a second battery cell; and a holder having a main body portion that extends between opposite surfaces of the first battery cell and the second battery cell and a supporting portion that extends from the main body portion to a side portion of the first battery cell and/or the second battery cell, wherein the supporting portion includes a groove extending on its outer surface. Through the technical solution of the present disclosure, the battery cells can be effectively fixed, space can be saved, and overall performance and structural strength of the battery pack can be enhanced.

Abstract: A vent valve and a vehicle battery pack having the same are provided. The vent valve includes a main body including a first end, a second end, and a through hole extending from the first end to the second end; a breathable membrane connected to the first end and covering the through hole; an upper cover covering the breathable membrane; and a first opening and a second opening in communication with each other. The first opening and the second opening are relatively offset in at least one of an axial direction or a circumferential direction. Compared with existing solutions, the technical solution of the present disclosure can provide enhanced protection for internal structures, such as the breathable membrane, further reduce the overall structural complexity of the vent valve, and enhance its functional durability, thereby increasing user satisfaction.

Abstract: The present disclosure relates to the field of vehicles, and specifically provides a valve for a battery pack. The valve comprises: a valve bracket having a first opening located at one end and a second opening located at the other end; a breathable membrane that covers the first opening; and a piston that covers the second opening and includes a hole closed by an openable sealing portion. The present disclosure also discloses a battery pack using the above-mentioned valve. By using the above-mentioned valve, the pressure inside and outside the battery pack can be balanced, effective waterproof and dustproof can be achieved, and the pressure inside the battery pack can be more effectively controlled when it rises rapidly.

Abstract: The present disclosure provides a battery pack and corresponding vehicle. The battery pack comprises: a tray; a mid-tray; a first battery array arranged in the mid-tray; a second battery array arranged in the tray; a first beam extending in a first direction and arranged in the tray; and array brackets extending in a second direction different from the first direction, wherein opposite ends of the first battery array in the first direction are connected to the tray through the array brackets.
