摘要： An attachment member attaches a bicycle battery pack to a frame of a bicycle. The attachment member includes a coupling member and a lock. The coupling member restricts movement of the bicycle battery pack relative to the frame while the attachment member is in an attachment state in which the battery pack is attached to the frame. The coupling member extends through a first frame portion of the frame and coupled to a first housing portion of the housing while the attachment member is in the attachment state. The lock is provided on the coupling member and switchable between a restriction state that restricts movement of the coupling member relative to the housing and the frame, and a release state that permits movement of the coupling member relative to the housing and the frame while the attachment member is in the attachment state.

摘要： The present disclosure relates generally to a battery module having a housing and a stack of battery cells disposed in the housing. Each battery cell has a battery cell terminal and a battery cell vent on an end of each battery cell, and the battery cell vent is configured to exhaust effluent into the housing. The battery module has a vent shield plate disposed in the housing and directly along an immediate vent path of the effluent, a first surface of the vent shield plate configured to direct the effluent to an opening between the shield plate and the housing, and a second surface of the vent shield plate opposite the first surface. The battery module also has a venting chamber coupled to the opening and at least partially defined by the second surface and a vent configured to direct the effluent out of the battery module.

摘要： An explosion-proof device includes a frame having a hollow shape, the frame housing an electrical component and a battery capable of supplying the electrical component with electric power. A protection device is configured to stop electric supply to the electrical component from the battery, if there is a risk of an explosive atmosphere entering the frame. The battery is housed in an explosion-proof container, within the frame, and thus it is possible to suppress damage to surroundings effectively even in case of ignition of an explosive atmosphere flowing into the frame by the battery.

摘要： A power battery and a power battery top cap structure for a power battery are provided. The power battery top cap structure includes first and second electrode assemblies, a lower insulation member, a top cap piece, and an abutment member. Both the first and second electrode assemblies are fixed on the top cap piece. The lower insulation member is fixed below the top cap piece. The lower insulation member includes, along an X axis, a snapping portion and a connecting portion. The abutment member extends along a Y axis and abuts between the connecting portion and the top cap piece so that a minimum distance between the connecting portion and the top cap piece along the Z axis is G3, where G3>0. G3 may be greater than a minimum distance between the connecting portion and the top cap piece when the lower insulation member is fixed without the abutment member.
