The invention provides an electric vehicle battery capacity monitoring method and device and an electric vehicle monitoring system. The method comprises the steps of obtaining capacity test parameters of an electric vehicle battery; carrying out modulus processing on the capacity test parameter and a preset test parameter to obtain an electric modulus capacity difference value; and sending a capacity estimation signal to a battery management system according to the electric mode capacity difference value, so as to estimate the residual capacity of the battery of the electric vehicle by adopting a corresponding residual capacity estimation metering algorithm. According to the method, the current operation condition of the electric vehicle battery is obtained by collecting the capacity test parameters, and then the current operation condition is compared with the preset test parameters, so that the difference between the current operation test state and the standard operation state of the electric vehicle battery is determined, and the difference characteristic value corresponding to the residual capacity of the electric vehicle battery is conveniently determined; and finally, an algorithm model is established according to the difference characteristic values, so that an estimation algorithm for the residual capacity of the battery can be conveniently determined, and the estimation accuracy probability of the residual capacity of the battery is effectively improved.
