Patents by Inventor Janina Stancu

Janina Stancu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8875768
    Abstract: A tape application machine and method are provided. The machine includes a nest device that moves along a linear rail from a first position to a second position. The nest device holds a battery cell therein. The machine further includes a tape application device that dispenses electrically non-conductive tape and applies a first portion of the tape on a first side of the battery cell. The machine further includes a tape bending device that conforms a second portion of the electrically non-conductive tape onto a second side of the battery cell. The machine further includes a tape compression device that compresses the tape on the first and second sides of the battery cell.
    Type: Grant

  • Patent number: 8802253
    Abstract: A weld validation system and method for a battery module are provided. The battery module has first and second battery cells and an interconnect member welded to first and second tabs of the first and second battery cells, respectively. The system includes a gripping device having first and second gripping fingers contacting the interconnect member. The system further includes a temperature sensor that generates a first signal indicative of a temperature of the interconnect member when a battery cycling device is discharging the battery module. The system further includes a computer that determines a first temperature value indicative of the temperature of the interconnect member based on the first signal.

  • Patent number: 8739400
    Abstract: A press assembly and a method for bending electrical terminals of battery cells are provided. The assembly includes a supporting member that holds a body portion of a cell thereon. The cell has first and second electrical terminals. The assembly further includes a lower plate having first and second dies that hold the first and second electrical terminals, thereon. The assembly further includes an upper plate having third and fourth dies, and guide rods disposed between the lower plate and the upper plate. The upper plate moves vertically on the guide rods relative to the lower plate. The assembly further includes an actuation assembly moving the upper plate toward the lower plate such that the first electrical terminal is bent into a first predetermined shape between the first and third dies, and the second electrical terminal is bent into a second predetermined shape between the second and fourth dies.

  • Patent number: 8736273
    Abstract: A testing system and a method for testing a battery cell are provided. The system includes a nest member that receives the battery cell, and a clamping device that secures a first battery tab between first and second connectors, and secures a second battery tab between third and fourth connectors. The system further includes a voltmeter that measures a voltage level between the first and third connectors when the first and second battery tabs are contacting the first and third connectors, respectively. The system further includes an ohmmeter that measures a first resistance level between a first portion of the outer housing and the first connector when the first battery tab is contacting the first connector.
