The invention discloses a pure battery redundant power device for a ship. The pure battery redundant power device comprises a pure battery redundant power assembly and a control system. The pure battery redundant power assembly comprises a shore power charging module, a redundant power station module, a power station control module and a load module, and the redundant power station module comprises a first lithium battery pack and a second lithium battery pack. The power station control module comprises a direct current contactor CB1, a direct current contactor CB2, a bypass switch CB3, a bus tie switch CB4, two diodes, a left daily inverter, a right daily inverter, a left propulsion inverter, a right propulsion inverter, a left isolation transformer and a right isolation transformer; diodes are installed in the reverse direction to achieve splitting operation, power redundancy standby is achieved, and ship power is ensured to guarantee the sailing safety of a ship to the maximum extent. Meanwhile, the marine frequency conversion power module based on the wide bandgap semiconductor is adopted, so that the size and the weight of the direct-current bus frequency conversion electric control equipment are greatly reduced. The invention further discloses a control method of the redundant power device.
