An arrangement for temperature measurement on a solid body includes an annularly closed elastic band, along the circumference of which at least two temperature sensors are arranged at a distance from one another, preferably in a manner distributed uniformly along the circumference of the annularly closed elastic band. The annularly closed elastic band preferably incudes an electrically non-conductive, thermally conductive and/or heat-resistant material. The arrangement for temperature measurement can further be arranged in a groove which runs around the solid body. The solid body may be, for example, a battery cell.

A packaging film includes a packaging portion and a pulling portion, and the pulling portion and the packaging portion are demarcated by a tear line. When the pulling portion is pulled, the tear line is disconnected, and the pulling portion is separated from the packaging portion. In a packaging face of the packaging portion, an area packaging a side wall of the battery is a glue-free area, and other areas are provided with a first adhesive. An adhesive face in the packaging portion is provided with a second adhesive. A part of the packaging face in the pulling portion is provided with a third adhesive, and the adhesive face in the pulling portion is a glue-free area.

Provided is a battery module including a plurality of battery cells stacked on one another and being capable of effectively preventing damage to the battery cells despite such a configuration. A battery module 1 includes a plurality of battery cells 10 stacked on one another and a battery cell support 2. The battery cells 10 each include a battery 11 and an exterior casing 12 accommodating the battery 11. The battery cell support 2 is disposed between the plurality of battery cells 10. The battery module preferably further includes a fixation film 6 wound around the plurality of battery cells in a stacking direction and fixing the plurality of battery cells.

A smart key for a vehicle includes: a base part; a first terminal part coupled to the base part and which makes contact with a first electrode of a battery so as to be electrically connected to the battery; a second terminal part disposed facing the first terminal part to form an insertion part where the battery is inserted and which makes contact with a second electrode of the battery to be electrically connected to the battery; a separation prevention part which extends from the second terminal to the base part and which abuts the side surface of the battery to prevent the battery from separating from the insertion part; and a pressure applying part which is connected to the second terminal part so as to enable contact with the battery and which maintains contact between the battery and the separation prevention part by an elastic restoring force.

The disclosed technology provides for a device and method related to powering an electronic stylus with a removable, integrated battery that acts as a structural segment and external casing along the long axis of the stylus body. The integrated battery incorporates interlocking features, which removes the need for an external tube around a battery cell. As a result, the electronic stylus has one structural component performing multiple functions (e.g., providing power, functioning as the stylus casing), which achieves a more lightweight and compact electronic stylus. The placement of the battery along the long axis can vary to provide comfortable weight distribution for writing, which can involve an interlocking interface at one end of the battery or at both ends of the battery (e.g., to interlock with one or both ends of the electronic stylus).

A battery pack includes a battery assembly and a tray. The battery assembly includes at least one battery unit, and the battery unit includes multiple cells, where the length direction of each cell is a first direction, and the multiple cells are disposed along a second direction. The tray includes at least one temperature adjustment unit, where the temperature adjustment unit includes a temperature adjustment flow channel and a confluence flow channel. Any one of the temperature adjustment flow channels is configured to exchange heat with at least one of the cells disposed along the second direction, and to exchange heat with at most one cell disposed along the first direction.

A battery module including a plurality of battery cells that prevents the movement of the battery cells due to impact and has excellent cooling performance of the battery cells includes a battery cell group including a laminate of a plurality of flattened rectangular battery cells stacked in a thickness direction of the battery cells, and a housing storing the battery cell group. The battery cell group includes a plurality of cell holders configured to hold the individual battery cells from both sides in the thickness direction, and a plurality of side plates disposed at both ends of the plurality of battery cells in a width direction via the plurality of cell holders. Each of the cell holders has a restriction portion configured to restrict movement of the corresponding battery cell in a direction intersecting the thickness direction, and fixing portions that engage with the side plates.

A battery pack exhaust duct includes a guide tube, an exhaust inlet, an exhaust outlet, and exhaust guide components. The exhaust guide components include first and second exhaust guide components. Each of the exhaust guide components has a first part and a second part. The first part has a first end that is nearer to the interior surface of the guide tube. The first part extends away from the interior surface, and toward the exhaust inlet. The second part has a first end that is nearer to the first part. The second part extends toward the interior surface. The second part has a second end that is apart from the interior surface. The second end of the second part of the first exhaust guide component and the second end of the second part of the second exhaust guide component are displaced along axis X along which the guide tube extends.

An energy storage unit mounting facility, having a basic body, which defines multiple mounting regions arranged vertically on top of one another for at least one electric energy storage unit. The electric energy storage unit is introducible into the mounting region in the horizontal direction and removable from the mounting region in the horizontal direction. Securing devices are provided to secure the electric energy storage unit in the mounting region.
