  • Method to compensate measurement error in a battery management system
    Patent number: 12638513
    Abstract: Voltage measurement techniques for battery cells in a battery management system (BMS) are described. Raw voltage measurements may include errors caused by ohmic losses due to cable impedances and other elements in the BMS. The techniques include performing a calibration cycle to generate correction values based on measured response with discharge switches in different states. The techniques also include scaling the correction values during runtime to correct for filter response errors in the voltage measurement.
    Type: Grant
    Filed: January 16, 2023
    Date of Patent: May 26, 2026
    Assignee: Analog Devices International Unlimited Company
    Inventors: Richard Rudolph Beauchemin, III, Cuyler Nicholas Latorraca, Patrick Wilhelm

  • PIGMENT DISPERSION COMPRISING SILANE-MODIFIED COLLOIDAL SILICA PARTICLES AND A WATER-SOLUBLE THICKENING POLYMER
    Publication number: 20220154029
    Abstract: The present disclosure relates to a pigment dispersion comprising silane-modified colloidal silica particles, an organic and/or inorganic pigment, a water-soluble thickening polymer in an amount of 0.1 wt. %, and water. The pigment dispersion is useful for tinting paint compositions, and exhibits excellent storage stability and washout resistance of the resulting coating. Another aspect of the present disclosure relates to a method for tinting a paint composition.
