A battery module has increased operating life by efficiently maintaining heat balance. The battery module may include a plurality of cylindrical battery cells arranged in a horizontal direction, a module housing including an upper wall, a sidewall and a lower wall to receive the cylindrical battery cells, at least one of the upper or lower walls having a plurality of cooling holes through the coolant flows in and out, at least two of the cooling holes having different sizes, and a cell frame including an insertion portion having an inner wall to wrap around at least part of an outer surface of each of the cylindrical battery cells, and a plurality of cooling passages connected to and in communication with the cooling holes and having a tubular shape extending in a vertical direction to allow the coolant to flow in and out.

A saddle riding vehicle includes: a motor which is a driving power source; a battery which powers the motor; a duct which supplies incoming wind to the battery; and a rear fender which is disposed above a rear wheel and houses the battery. The rear fender includes, behind the battery, a discharge hole which discharges the incoming wind supplied by the duct.

Disclosed is a battery module. The battery module includes at least one battery cell, a casing configured to surround the battery cell and having at least one opening formed therein; and a thermal interface material (TIM) interposed between the casing and the battery cell and exposed out of the casing through the opening of the casing.

A wearable battery pack includes a battery pack body, a battery cell and a housing accommodating a battery cell and a wearable device capable of wearing so that the battery pack body at least be worn on a user's back. The battery pack body has a heat dissipation channel running through one side of the battery pack body to the opposite side. The side of the battery pack body which is penetrated by the heat dissipation channel is located between the back of the user and the other side when the user carries the battery pack body.

An electric Vehicle (EV) includes a frame extending rearwards from the front portion of the EV towards a rear portion of the EV. A floorboard structure is disposed below the frame and is supported by the frame. A battery is disposed in a cavity defined between the floorboard structure and the frame. A first heat-generating component is disposed in the rear portion of the EV. The EV includes a duct extending from the front portion to the first heat-generating component to conduct air from the front portion to the first heat-generating component. A second heat-generating component is disposed in the cavity. The duct includes: an inlet facing the front portion to receive air from the front portion; a first outlet facing the first heat-generating component to supply air to the first heat-generating component; and a second outlet facing the second heat-generating component to supply air to the second heat-generating component.

Disclosed is a battery pack which has a simple structure, small volume and weight, and efficient cooling performance. The battery pack includes a module assembly including a plurality of secondary batteries, and a plurality of cartridges configured to be stacked with each other and surround an outer circumference of the secondary batteries at an outer side, the plurality of cartridges being at least partially made of thermally-conductive material; and a pack case having an empty space therein to accommodate the module assembly and at least partially made of thermally-conductive material to discharge heat of the module assembly.

A battery pack structure includes a chamber, a cooling duct arranged outside the pack case, and a connector that communicates the chamber and the cooling duct with each other. The connector includes a first opening, which is connected with the chamber in a state of being sealed by a first sealing member, a second opening, which is connected with a cooling duct in a state of being sealed by a second sealing member, a first sealing surface, which is formed in a peripheral part of the first opening and is either a tube-shaped surface or a plane that faces a chamber inlet surface though the first sealing member, and a second sealing surface, which is formed in a peripheral part of the second opening and is a tube-shaped surface or a plane that faces a duct outlet surface through the second sealing member.
