An HV energy storage device for a motor vehicle as well as a method for operating the HV energy storage device.

A battery device includes a case, a cell disposed within the case, and first and second conductive tabs each electrically connected to the cell and partly enclosed by the case. The first conductive tab has an elastic portion exposed from the case and compressible or stretchable when a force is applied thereto. By having the elastic portions that are elastically deformable, the effects of push or pull resulting from the swelling of the cell and case on the conductive tabs may be reduced. Consequently, damages or breakages of the conductive tabs can be avoided and the safety of battery device may be improved.

A battery module is provided. The battery module includes pouch-type battery cells stacked on each other and electrically connected in series and/or in parallel. Toward an electrode lead of one pouch-type battery cell, electrode leads of other pouch-type battery cells are biased to allow ends of the electrode leads to be overlapped. In particular, each of the pouch-type battery cells has an R bending portion at which a boundary region between a terrace of a pouch case and the electrode leads is bent toward a direction in which the electrode leads are biased.

This disclosure details exemplary battery pack designs for use in electrified vehicles. Exemplary battery packs may include a polymer-based enclosure assembly having features for both retaining components and transferring loads inside the battery pack. The battery packs may include one or more snap-in features for retaining the components and one or more foam spacers for separating adjacent battery arrays and establishing a load transfer path inside the battery pack.

A safety apparatus (20) for a battery (80) has a base (22) for a vehicle (10), sensors (31, 32, 33, 34) and an evaluation apparatus (40). Each sensor (31, 32, 33, 34) is designed to generate a sensor signal (35) on a basis of a deformation of the base (22) and to supply the sensor signal to the evaluation apparatus (40). The evaluation apparatus (40) ascertains from the sensor signals (35) both first information about the location of the deformation of the base (22) and second information about the level of the deformation, and uses the first information and the second information as a basis for determining whether a first state (Z1) is present, in which a driving mode can be maintained, or whether a second state (Z2) is present, in which a driving mode can no longer be maintained.

A battery cell, a battery, an electrical apparatus, and a method and a system for manufacturing a battery cell are provided. The battery cell comprises: a case having an opening; an electrode assembly provided within the case; an end cover assembly for closing the opening, wherein the end cover assembly comprises an end cover, an insulating member and a connection adapter member, the end cover is provided with an electrode terminal, and is configured to cover the opening and is connected to the case, the insulating member is provided on one side of the end cover facing the electrode assembly, and the connection adapter member is used for being electrically connected to the electrode terminal and to the electrode assembly; and a buffer member provided on one side of the insulating member facing the electrode assembly.

In general, the presently disclosed technology relates to identification of cancer subtypes. More specifically, the technology relates to methods for determining molecular drivers of cancer and/or progression using a multivariate image data and statistical analysis of in-situ molecular markers and morphological characteristics in the same cells of a biological sample suspected of b cancer. This analysis takes place after a single acquisition that obtains the molecular and anatomic morphology data in parallel. The analysis compares specific morphological and molecular markers to known samples exhibiting particular genetic drivers of the cancer. This method provides statistical information that allows for an increased confidence in the identification of specific molecular drivers of the cancer.
