  • Publication number: 20250135946
    Abstract: A method for monitoring a battery module in a vehicle includes selecting an upper cut-off voltage and a lower cut-off voltage for the battery module. The method includes charging the battery cell from an original state to a first benchmark voltage greater than an upper cut-off voltage, via a first charging process. The method includes discharging the battery cell from the first benchmark voltage to a second benchmark voltage less than a lower cut-off voltage, via a first discharging process. The battery module is then charged from the second benchmark voltage to the first benchmark voltage, via a second charging process. The method includes obtaining a ratio of a discharging capacity to a charging capacity of the battery module. Operation of the vehicle is controlled based in part on the ratio, including taking at least one remedial action if the ratio is less than a predefined threshold.

  • Publication number: 20250139828
    Abstract: Aspects of the present disclosure include methods, apparatuses, and vehicles for performing intrinsic calibration of the cameras in the vehicle. A processor may acquire plural images of a target captured by the camera at different locations. For each image, the processor may tone map the image, binarize the tone-mapped image, define a structuring element based on the digital form of the shape of the target, perform morphology on the image to align and calibrate the structuring elements, filter the target and modify each of the other pixels to black, and compile an output image. Based on the calibration, the principal point values may be shifted to account for discrepancies and store calibrated values in each camera.
