The invention provides an electric vehicle power limiting method and system based on an advanced power reduction strategy. The method comprises the following steps that the numerical value interval where the lowest battery cell voltage of a battery pack is located is judged in real time; if the lowest cell voltage is in the first interval, the power limiting operation is not executed; if the lowest cell voltage is in a second interval, executing a linear power reduction operation; if the lowest cell voltage is in a third interval, reducing the power to a first set value according to a set power reduction rate; if the lowest cell voltage is in a fourth interval, instantly reducing the power to a second set value; wherein the first interval, the second interval, the third interval and the fourth interval are continuous and full-range coverage intervals from large to small in sequence. The driving experience of a vehicle owner is improved, and irreversible damage caused by over-discharge of the battery is avoided.

This application provides a channel angle estimation method, apparatus, electronic device, and readable storage medium, comprising: acquiring a discrete beam set of a preset angle domain and the pointing angle, radiation pattern, and received power corresponding to each beam in the discrete beam set; determining a center beam and acquiring the power difference ratio between the center beam and a target neighboring beam, wherein the center beam is the beam corresponding to the larger value of the received power, and the target neighboring beam is one of the adjacent beams surrounding the angle domain of the center beam; mapping the power difference ratio to an angle offset according to the radiation pattern corresponding to the center beam; and correcting the pointing angle corresponding to the center beam according to the angle offset to obtain the estimated angle.
