  • Patent number: 9368772
    Abstract: A method for fabricating a solid state battery device. The device can include electrochemically active layers and an overlaying barrier material, with an inter-digitated layer structure configured with a post terminated lead structure. The method can include forming a plurality of battery device cell regions (1-N) formed in a multi-stacked configuration, wherein each of the battery device cell regions comprises a first current collector and a second current collector. The method can also include forming a thickness of a first and second lead material to cause formation of a first and second lead structure to interconnect each of the first and second current collectors associated with each of the plurality of battery device cell regions and to isolate each of the second current collectors extending spatially outside of the battery device cell region within a first and second isolated region, respectively.

  • Patent number: 8190384
    Abstract: A method of the present invention using a prediction process including a battery equivalent circuit model used to predict a voltage and a state of charge of a battery. The equivalent circuit battery model includes different equivalent circuit models consisting of at least an ideal DC power source, internal resistance, and an arbitrary number of representative parallel resistors and capacitors. These parameters are obtained a priori by fitting the equivalent circuit model to battery testing data. The present invention further uses a correction process includes determining a corrected predicted state of charge of the battery; and storing the corrected state of charge of the battery in a storage medium. In the present invention, an expectation of the predicted voltage of the battery and an expectation of the predicted state of charge of the battery are obtained by an unscented transform with sigma points selected by a Gaussian process optimization.
