An electric vehicle (1) has a battery (2) in an underfloor arrangement. The battery (2) is arranged in a battery space (4) that is delimited by body members (5, 6, 7, 8) of a body (3). The battery space (4) also is delimited at a bottom side of the electric vehicle (1) by way of a protective plate (9). The battery (2) has a connection element (10, 11) at least on a side oriented toward one of the body members (7, 8), and the body member (7, 8) has a recess (12, 13) in which the connection element (10, 11) is arranged.

A battery system includes battery cells arranged and adhered to a carrier. One or more side walls are bonded with adhesive to the battery cells to provide support, and a current collector assembly is also adhered on one axial side of the battery cells. One or more dividers may be included to maintain electrically isolation between the parallel connected battery cell groups. The other axial side of the battery cells is adhered to a cooling plate. A similar structure is bonded with adhesive to the other side of the cooling plate to form a compact battery system. Shear walls, busbars, terminal busbars, and an isolation bracket with a mounted Electronic Control Unit are bonded with adhesive to the assembly to form the battery system. Each adhesive, or type of adhesive, may exhibit specified criteria and requirements such as strength, thermal conductivity, electronic conductivity, curing requirements, or a combination thereof.

A battery pack enclosure, a battery module, and a method are provided to detect damage to in a crash event. The battery pack enclosure may include a plurality of battery modules, wherein each battery modules includes a plurality of adjacent battery cells. The battery pack enclosure may also include a sensor and an electronic control unit electronically connected to the sensor, the electronic control unit configured to monitor the sensor to detect damage to the battery pack enclosure. The sensor may comprise a mesh of resistive wires, and the electronic control unit monitors the overall resistance of the mesh resistive wires. The overall resistance of the mesh resistive wires can be used to determine whether there is damage to the battery pack enclosure. If damage is detected, the damage can further be located, and an alert sent.

A vehicle system may include an impact screen for reducing damage in a collision involving the vehicle. The impact screen may be disposed in a cavity of the vehicle system between a motor unit and a battery to reduce a likelihood of impact and/or a force of an impact between the motor unit and the battery. The impact screen may be fixed at opposite sides of the vehicle, such that motor unit moves relative to the impact screen during the collision.

Systems and methods for identifying thermal run-away events in a battery pack can include using sensing circuits made up of series- or parallel-linked thermistors to measure subsets of the individual battery cells in a battery pack. Using multiple sensing circuits, a monitoring system can positively identify when a threshold temperature of any single battery cell has been reached even though individual temperatures are not monitored, and can generate a signal indicative of a thermal run-away event based on the detected temperature.

A composite panel for a battery pack including a composite panel for a battery pack provided on at least one side of a battery cell, and implemented by comprising: a heat dissipation sheet part; a heating sheet part including a heating circuit pattern formed in a predetermined area; and a sensor unit for detecting any one or more of external temperature and swelling of the battery cell. According to this, the composite panel for the battery pack and the battery pack comprising same can simultaneously express the effects of detecting the temperature and swelling of the battery cell by including the sensor unit, and very easily controlling the temperature of the battery cell by having excellent heat dissipation characteristics by including the heat dissipation sheet part, and predetermined heat generation due to the heating sheet part.

A battery module includes a plurality of battery cells; a module housing configured to accommodate a cell stack including the plurality of battery cells; and a sprinkler provided through the module housing at one side of the cell stack in a stacking direction, and the sprinkler includes a coupler positioned at an outer side of the module housing and connected to a supply tube that supplies a cooling fluid; a sprinkler head positioned at an inner side of the module housing and connected to the coupler; and an insulation cover assembly having an insulation cover configured to cover the sprinkler head and an impeller assembly configured to cover an opening formed at one side end of the insulation cover in a longitudinal direction.

A cell holder for a battery cell includes an intake in which the battery cell is receivable. The cell holder is stackable with additional cell holders in a module frame in which a battery that has a plurality of battery cells is receivable. The cell holder is guidable in the module frame relative to the module frame by a guiding device.

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).
