Abstract: The disclosed systems and methods provide a novel framework that provides mechanisms for a hands-free, autonomous electrical connection of an electric charger to an electric vehicle (EV), and subsequent charging. The disclosed framework utilizes an automated connection device (ACD) as an intermediary between the charger and the EV. The ACD is configured for automatically determining a precise location of the charging inlet on the EV and then automatically establishing an electrical connection with the EV so that the EV can receive a charge. The ACD performs the disclosed precise positional and directional navigation to the EV inlet based on deep neural network analysis of captured imagery of the inlet. In some embodiments, the images can be modified so as to highlight and/or assist the ACD's navigation towards to the inlet in order to maximize invariance.

Information regarding the actual voltage and/or frequency of the drawn electrical power, and/or the frequency and magnitude of an ultrasonic wave transmitted from the generator to an applicator tool used to weld an object can be utilized by an estimator to estimate the weld energy dissipated at the weld site and/or generate a power curve for the welding operation. Using information from the estimator, the controller can determine adjustments for variables for the current and/or future welding operations. Further, welding may not commence until a clamping force exerted on the object satisfies a clamping force set point.
