The invention provides an estimation method, device and system of the driving range of an electric vehicle. The method comprises the following steps: a combination instrument obtains the parameters of a power battery and the speed of the electric vehicle every preset time, wherein the parameters of the power battery comprise the total energy of the battery, the SOC (state of charge) of the battery, the total current of the battery and the total voltage of the battery; real-time power value Q is obtained according to the received total current and total voltage of the battery; real-time range integrated value S is obtained according to the received speed of the electric vehicle; the average power consumption R of the electric vehicle is obtained according to the Q and the S; the driving range of the electric vehicle is obtained according to the R, the total energy of the battery and the SOC of the battery. According to the method, adaptive real-time parameter collection and calculation for a single vehicle are achieved, and error is greatly reduced through real vehicle application.
