摘要： The present invention provides a method of producing a set of mechanically connected cells (200), especially for use in a vehicle traction battery (704). The method comprises producing a plurality of rows of mechanically connected cells in a first jig, and subsequently connecting the cells together in a second jig. Advantageously, the method may substantially reduce the problem of tolerance stack associated with mechanically connected cells.

摘要： A method for inspecting a power storage device for short circuit includes: adjusting a plurality of power storage devices to a first device voltage; restraining the power storage devices; measuring a pre-leaving device voltage, leaving the power storage devices, and measuring a post-leaving device voltage; obtaining a voltage drop rate; and determining whether or not a restrained device is short-circuited using a voltage drop rate. The method further includes: calculating a largest adjustment timing difference between an oldest adjustment completion time of an oldest adjusted device and a newest adjustment completion time of a newest adjusted device, after adjusting the voltage but before measuring the pre-leaving voltage; obtaining a shortest standby time from the largest adjustment timing difference; and deferring the measuring of the pre-leaving voltage until the shortest standby time elapses.

摘要： Presented are metalworking systems for forming metallic workpieces, methods for making/operating such metalworking systems, and battery module cell tabs bent by a multistage cluster-and-bend press. A metalworking system includes a grouping tool and a contouring tool that both align adjacent a workpiece support structure, such as a base plate of a battery module housing buttressing a stack of battery pouch cells. The grouping tool, which may include a first reciprocating plunger or plunger head, presses together a stack of metallic workpieces to thereby form a workpiece set having a first bend profile and a first length. The contouring tool, which may include a second reciprocating plunger or a pair of plunger fingers mounted on the plunger head, is attached to the grouping tool and bends the workpiece set to a second bend profile, distinct from the first bend profile, and a second set length, shorter than the first set length.

摘要： The embodiments describe a system and the corresponding assembly techniques of a battery submodule top cover. The battery submodule top cover has at least one electrical hybrid interconnect coupled to a substrate. The hybrid interconnect comprises at least a first portion made of a first metal type, and a second portion made of a second metal type. The first portion and the second portion of the hybrid interconnect are joined together such that an electrical connection may be made between two battery cell tabs where each battery cell tab is made of a different type of metal.
