    摘要： The present disclosure relates to a battery current monitoring method, a controller and a circuit. The method is applied to a current monitoring circuit, the current monitoring circuit includes a hall sensor, a controller and a constant voltage source. The current monitoring method includes: acquiring, by the controller, an output voltage of the constant voltage source and a first analog-to-digital conversion value of the output voltage of the constant voltage source; determining an analog-to-digital conversion correction coefficient based on the output voltage of the constant voltage source and the first analog-to-digital conversion value; acquiring a second analog-to-digital conversion value of an output voltage of the hall sensor and a third analog-to-digital conversion value of a supply voltage of the hall sensor; and determining the battery current based on the analog-to-digital conversion correction coefficient, the second analog-to-digital conversion value and the third analog-to-digital conversion value.

    摘要： A method for estimating a fundamental component of an AC voltage includes receiving a timely varying measurement signal of the AC voltage; parametrizing a fundamental component of the AC voltage; and determining parameters of the fundamental component based on minimizing a cost function. The fundamental component has a rated frequency, a variable amplitude and a variable phase shift. The cost function is based on an integral of a norm of a difference between the measurement signal and the parametrized fundamental component via a time horizon. The time horizon starts at an actual time point and goes back via a predefined length. The cost function includes a term based on a norm of the difference between a value of the fundamental component at the actual time point and a value of a previously estimated fundamental component at the actual time point, where the previously estimated fundamental component has been determined for a previous time point.
