Abstract: A control unit in a battery management apparatus discharges constant direct current from a battery for a predetermined time period or charges the battery with the constant direct current for the predetermined time period to diagnose a state of the battery. A change point is identified where a rise in voltage given by subtracting open circuit voltage of the battery from measured voltage of the battery is varied from a curved line shape to a straight line shape with respect to transition of an increase of a value in which an elapsed time since start of charge-discharge is defined as a square root of time. A rise in voltage from the voltage when the charge-discharge is started to the change point is identified as a rise in voltage caused by resistance components of electrolyte, a negative electrode, and a positive electrode of the battery and a rise in voltage after the change point is identified as a rise in voltage caused by a diffusion resistance component of the battery.

Abstract: A method for generation of an augmented point cloud with point features from aggregated 3D coordinate data and related device. The method comprises receiving a current point cloud in the form of 3D coordinate data in ego coordinates from one or more detection and ranging (DAR) devices of a vehicle. Features are extracted from the current point cloud. A previous point cloud is transformed into ego coordinates using a current location of the vehicle. Each point in the previous point cloud is transformed to align with a corresponding point in the current point cloud to generate a transformed point cloud. The current point cloud is aggregated with the transformed point cloud to generate an aggregated point cloud. The current point features are aggregated with the point features of the transformed point cloud to generate aggregated point features.
