The invention provides an electric pump control method and system. The electric pump control method comprises the following steps that a current rotating speed, a current and a current voltage of theelectric pump are collected; whether the electric pump is in a normal operation mode or not is judged according to the current and the current voltage; if a current rotating speed is in a normal operation mode, whether the current rotating speed is in a calibrated rotating speed range or not is judged; and if the rotating speed is not within the range of the calibrated rotating speed, the currentrotating speed is corrected, and a correcting result is recorded. According to the the electric pump control method and system, the problem that an electric pump control method in the prior art is lowin efficiency can be solved, and the electric pump can be effectively controlled.
