The invention discloses a propulsion system of a pure electric ship and a control method of the propulsion system. The system comprises a main control module used for being connected with an external interface of a propulsion system; each propulsion subsystem comprises a power battery, a slave control module, a battery management module, a high-voltage box, a motor controller and a motor, and the slave control module is used for interacting with the master control module and controlling the battery management module and the motor controller; the energy routing controller distributes energy of the power batteries of the at least two sets of propulsion subsystems; the power batteries of the at least two sets of propulsion subsystems respectively control the motor controllers of the at least two sets of propulsion subsystems through the energy routing controller and the high-voltage boxes of the at least two sets of propulsion subsystems under the control of the battery management modules of the at least two sets of propulsion subsystems; and the motors of the at least two sets of propulsion subsystems are respectively controlled. According to the technical scheme provided by the embodiment of the invention, the electric energy utilization rate of the pure electric ship is improved.
