The voltage and capacity of the battery module are modifiable by changing the length of the scaffold profiles.

Abstract: A battery operated hair dryer is provided that includes a housing and a battery pack including at least one battery cell, with the battery pack electrically connected to a battery management and control module. Further including at least one switch to control operation of the hair dryer and a heating assembly that includes a fan attached to a motor, and at least one heating element, with the heating element positioned such that air passing through the heating assembly may be heated to a temperature greater than the ambient air temperature, and wherein the battery management and control module are electrically connected to the at least one fan and the at least one heating element, and wherein the battery management and control module adjusts an electrical current delivered from the battery pack to the fan and heating element.

Abstract: A device is disclosed. The device is a battery module frame. The battery module frame includes a rigid top integrated with an enclosure which surrounds a cavity into which a battery cell fits. The enclosure includes a compliant portion which forms a flex wall. The flex wall flexes to apply a radial load on a battery cell installed in the enclosure. The radial load applied by the flex wall secures the battery cell in the enclosure. The rigid top maintains the top of a battery cell installed in the battery cell holding frame in a stationary position to maintain electrical connections on the battery cells. The device further includes a frame of multiple enclosures defining multiple cell cavities for holding battery cells. The rigid top maintains the top of each battery cell installed in the frame in a stationary position to maintain electrical connections on the battery cells.

Abstract: A battery module construction that provides passive resistance to propagation of cell failure, such as thermal runaway. The walls of cells of a battery module may be thermally isolated from each other by securing cells in a frame formed of thermal insulating material, separating the cells from one another, thereby limiting thermal energy from propagating directly between adjacent cells. A vent layer may permit ejection of hot gases and other ejecta into an air gap above the cells, venting the ejecta and dissipating thermal energy. The vent layer may be formed from, e.g., a frangible layer of dielectric gel, or a plastic vent tray with apertures for venting of ejecta and passage of wiring with collectors mounted over the vent tray. A heat sink or cooling module may be thermally coupled to an opposite end of cells to further aid thermal energy removal from the module.

Abstract: A battery module is formed from a plurality of battery cells having top and bottom electrodes. Top and bottom collector plates overlay, and are electrically connected with, the battery cell top and bottom electrodes. The collector plates may be formed wholly or primarily from copper. Cell apertures may be formed within the collector plates overlying each cell, with collector arms extending into said apertures for connection with an underlying cell electrode. The collector arms may include a fusible link for each cell. A bridge collector plate may span subsets of cells, and include a module-level fusible link formed therein. A current concentrator, such as a dimple or depression, may be formed in a collector arm to facilitate resistance welding of the copper collector plates to underlying battery cells, which may include electrodes formed from steel or other material more resistive than the copper collector plates.

Abstract: An assembly for monitoring the operation of a large format battery module. Printed circuit boards may be routed within a battery module to electrically interconnect collector structures with a battery module monitoring circuit. Flexible printed circuits (FPCs) may be wrapped around one or more sides of a battery module and secured to it, such as via adhesive. Voltage monitoring FPCs may be applied to one or more side surfaces to electrically interconnect battery module collector structures with a monitoring circuit. Temperature monitoring FPCs may interconnect temperature sensors with the monitoring circuit. In some embodiments, one or more serpentine PCBs may be installed in a central channel between cells beneath a plurality of collector structures. The collector structures may include extensions overlaying the serpentine PCBs for direct welding to a steel pad on one of the serpentine PCBs.
