摘要： A traction battery includes a stack of cells each having two terminals. Sets of terminals are connected to busbars to electrically connect the battery cells. The busbars have a base, a set of connecting portions, and a set of stiffeners. The terminals have protruding portions and receding portions. As the busbar is positioned with respect to the battery stack, the connecting portions guide the receding portions into position by deflecting the protruding portions. The receding portions are then welded to the connecting portions. The deflected protruding portion forces the parts to be welded together, eliminating a need for clamping during the welding process.

摘要： A module layer and to a battery system made therefrom, which, as a device for supplying and storing electrical energy between two final end components, comprises a number of battery modules that are electrically connected to one another in series. Each module here consists of a number of elementary cells, which are generally lithium-ion batteries. The module layer is embodied as a structural unit, wherein the cells in the module layer are positioned next to one another in a tray, in an upright position on a base element of the tray, and are enclosed by an outer frame that is embodied as a heat sink and constitutes the rim of the tray, the outer frame has a seal, and the module layer has a section of a central shaft into which bus bars protrude, which produce a conductive connection with the cells of the respective module layer.

摘要： A battery configured to support a relatively high rate of energy discharge relative to its capacity for energy intensive therapy delivery. The battery includes a feedthrough insulator cap disposed within the interior of the battery on at least a portion of a ferrule, at least a portion of an insulator, and at least a portion of a pin, which define a feedthrough extending through an enclosure of the battery; a first electrode disposed within the enclosure and electrically coupled to the pin; a second electrode disposed within the enclosure and separated a distance from the first electrode; and an electrolyte disposed between the first electrode and the second electrode. During operation of the battery, the feedthrough insulator cap reduces dendrite formation on at least a portion of the ferrule, the pin, or both.
