    摘要： A vehicle, provided with a vehicle door assembly. The vehicle door assembly includes an exterior vehicle door handle, and the exterior vehicle door handle includes a base and a handle grip. The base is provided with a handle cavity and configured for being mounted on a vehicle door. The handle grip is rotatably mounted on the base between a closed position and an open position. When the handle grip is in the closed position, an outer surface of the handle grip does not protrude from an outer surface of the vehicle door and covers the handle cavity, and when the handle grip rotates from the closed position to the open position by rotating towards an interior of the handle cavity, the handle grip does not protrude from the outer surface of the vehicle door and the handle cavity is exposed.

    摘要： A method of obtaining battery capacity, includes: acquiring a voltage-capacity curve of a battery; performing differentiation on the voltage-capacity curve to obtain a voltage differential-capacity curve; identifying wave crests in the voltage differential-capacity curve; calculating heights and widths between each wave crest and the adjacent wave trough on the left and the right;
    calculating a determination index p according to the heights and the widths; determining a voltage knee point in the voltage-capacity curve according to a wave crest with a minimum determination index; acquiring a reference capacity value corresponding to the voltage knee point in the voltage-capacity curve; after the battery reaches a full-charge state, acquiring charging electric energy of the battery for charging from the voltage knee point to the full-charge state; and obtaining a capacity of the battery based on a sum of the reference capacity value and the charging electric energy.
