A state-of-charge acquisition method is applied to the charging device for charging an electric vehicle, and the method includes: acquiring an initial electric quantity data value upon start of charging of the electric vehicle with a VCI device; acquiring a charging current of a battery of the electric vehicle during a charging process; acquiring an electric quantity of the battery at a current moment on the basis of the charging current; and acquiring the electric quantity data value at the current moment on the basis of the initial electric quantity data, the electric quantity, and a rated total capacity of the electric vehicle, the electric quantity data value indicating a state-of-charge of the battery at the current moment. In this way, the electric quantity data value of the battery during the charging process can be obtained in real time.
