FIG. 6 is a schematic view showing a state in which an ISO container type large capacity battery according to an embodiment of the present invention is mounted, Fig.

5 and 6, a ship equipped with an ISO container type large capacity battery 10 according to an embodiment of the present invention includes a storage room 30 for storing an ISO container type large capacity battery 10, (Not shown).

The storage room 30 is a space for mounting and receiving the large capacity battery 10 from above the vessel, for example, a surface of the vessel, for example, a space in which the deck is settled inward.

The storage chamber 30 may include an inner wall 32 surrounding the storage chamber 30. The inner wall 32 may be formed of a cushioning member for protecting the ISO container type large capacity battery 10 inserted into the storage room 30 from an external impact and may be formed of a cushioning member for preventing the temperature of the inside of the storage room 30, As shown in Fig.

The storage chamber 30 includes a first connection electrode 34 and a second connection electrode 36 connected to the first exposed electrode 110 and the second exposed electrode 120 of the large capacity battery 10 . The first connection electrode 34 and the second connection electrode 36 may be disposed so as to be exposed on the lower inner wall 32 of the storage chamber 30, respectively. The first connecting electrode 34 and the second connecting electrode 36 are in contact with the first exposed electrode 110 and the second exposed electrode 120 respectively when the large capacity battery 10 is placed inside the storage room 30 And can be electrically connected.

Further, the large capacity battery 10 according to an embodiment of the present invention includes a plurality of exposed electrodes 100 exposed to the outside, and each of the exposed electrodes is electrically connected to the connection electrode provided on the ship, It is possible to connect between the large capacity battery 10 and the power system 20 of the ship without connecting and disconnecting operations.

FIG. 7 is a block diagram exemplarily showing a power system 20 of a ship including a large-capacity battery according to an embodiment of the present invention.

Referring to Figure 7, a ship including a large capacity battery 10 according to an embodiment of the present invention includes a power grid 21, one or more generators 24 connected to a power grid 21, a power grid 21, A plurality of load elements 25 coupled to the power grid 21, and a controller 22. The controller 20 may be a microprocessor,

The power grid 21 may correspond to one or more electrical nodes that flow through the in-ship power system 20. The power grid 21 may refer to a collection or network of one or more electrical cables capable of forming one or more electrical nodes to provide power to the load elements.

In the embodiment shown in FIG. 7, the power grid 21 is illustrated as forming an AC grid with an AC voltage applied thereto. However, the present invention is not limited thereto, and the power grid 21 may form, for example, a DC grid to which a DC voltage is applied.

A plurality of generators 25 are connected to the power grid 21 and can supply electricity to the power grid 21. [ The plurality of generators may be composed of, for example, diesel generators capable of generating large capacity electric power of 200 KW or more. Each generator can generate an AC voltage having a specific voltage level and frequency, and can be self-regulated to maintain that particular voltage level and frequency. For example, the diesel generator may self-regulate the amount of fuel consumed to provide an AC voltage of 440 V and 60 Hz, thereby maintaining the voltage and frequency at 440 V and 60 Hz provided to the power grid 21 .

The ship's internal load elements can be connected to the power grid 21 and can be powered from the power grid 21 to perform the corresponding functions of the load elements.

If the load elements consume a lot of power and the load of the power grid 21 rises, the AC voltage amplitude of the power grid 21 may become smaller or the frequency of the AC voltage of the power grid 21 may decrease. In this case, it can be interpreted that the load of the power grid 21 is increased, and a plurality of generators can be adjusted to provide an operating load corresponding to the increased load. Specifically, when the load on the power grid 21 is increased, the plurality of generators can increase the amount of fuel consumed, thereby adjusting the amplitude and frequency of the AC voltage to a certain level and frequency, e.g., 440 V and 60 Hz It is possible to increase the movable load provided to the power grid 21. [

In addition, the plurality of generators can receive the generator control signal from the outside, and in response to the received generator control signal, adjust the operating load corresponding to the amount of power that the plurality of generators produce and supply to the power grid 21 .

That is, in one embodiment of the present invention, the plurality of generators may operate in an external regulating manner to regulate the operating load of the generator according to an external generator control signal, and may operate independently of the instantaneous voltage fluctuation of the power grid 21 network The amount of the generated power load can be maintained in an externally adjustable manner.

The plurality of load elements 25 in the ship may be various application devices and mechanisms that perform functions by connecting to the in-ship power system 20. [ The plurality of load elements 25 may be connected to the power grid 21 via a transformer and the transformer may be operable to reduce or boost the voltage of the power grid 21, To the load element (25) of FIG.

In one embodiment of the present invention, the plurality of load elements 25 may include an in-vessel device / mechanism load L_A, a plurality of thruster (s) L1 to Lm.

The onboard instrument / instrument load (L_A) may be a conventional instrument / instrument operated using electricity in a ship, for example, a control system, household appliances, lighting, and the like.

The plurality of thruster (L1 to Lm) may be a combination of an electric motor and a screw, which provide auxiliary propulsion power in addition to the main propeller for the ship. For example, the thruster L1 may be provided in a direction perpendicular to the longitudinal direction of the ship A bust thruster that provides propulsive force, or an azimuth thruster that can provide thrust across all directions.

In one embodiment of the present invention, the vessel may be a vessel performing dynamic position control. That is, the ship according to an embodiment of the present invention controls the dynamic position of the ship by using a thruster as auxiliary power means so as to maintain the equilibrium of the ship with respect to the dynamic change of the position and angle of the ship with respect to time.

Since the operation of the thruster for dynamic position control of the ship corresponds to the dynamic change of the position and the angle of the unspecified ship, the fluctuation of the instantaneous load fluctuating with respect to the load consumed on average by the ship during the non- You can.

In order to cope with such fluctuations in the momentary load applied to the power grid 21 in such a vessel, the plurality of generators in the vessel must have a sufficient margin of the load that can be supplied and, for example, In order to supply a load equal to or greater than the average load, one generator must have a sufficiently large power supply capability as compared with the average load, or the additional generator must maintain the power generation state at the minimum load.

For example, even if the maximum load that can be supplied by the first generator is equal to or more than the average load consumed in the ship, considering the margin for the moving load of the thruster running for an unspecified time period for dynamic position control, It is necessary to maintain the standby state. At this time, the second generator must maintain a power generation state that supplies a load relatively lower than its capacity, which may cause the fuel efficiency of the generator to be deteriorated.

The large capacity battery 10 may be connected to the power grid 21 via a DC to AC transformer or an AC to DC transformer and may serve as an auxiliary power supply for the in-ship power system 20. [ The large capacity battery 10 can be supplied with electric power from the electric power grid 21 to charge or discharge electric power to the electric power grid 21. [

The large capacity battery 10 can repeat charging or discharging so as to maintain or follow preset charging values. For example, the large capacity battery 10 may be self-regulated to start charging when discharged to a predetermined lower limit charging value and to be discharged when charged to a predetermined upper limit charging value. Further, for example, the large capacity battery 10 can be self-regulated in charging and discharging so as to follow a predetermined charge / discharge target value which fluctuates with time.

Furthermore, the large capacity battery 10 can switch the charging or discharging state of the large capacity battery 10 in response to an external battery control signal. For example, when the battery control signal corresponding to the charge start signal is applied to the large capacity battery 10, the large capacity battery 10 starts charging, and when the battery control signal corresponding to the discharge start signal is applied, 10 can begin to discharge, and the large capacity battery 10 can be controlled externally.

The plurality of generators 24 can transmit to the outside, for example, an external controller 22, the generator load information regarding whether or not each generator is operating and the operating load. Also, the large capacity battery 10 can transmit information to the external controller 22, for example, about the present charge level of the large capacity battery 10, the number of times of charge and discharge, the charge and discharge duration, and the like.

The controller 22 can provide a generator control signal to each of the generators to control the operation of each generator and the degree of the operational load. Also, the controller 22 can control the charging or discharging of the large-capacity battery 10 by providing a battery control signal to the large-capacity battery 10. The controller 22 can also be connected to the power grid 21 via the sensor 23 and can detect the voltage of the power grid 21 by the sensor 23.

The controller 22 of the power system 20 of the ship can receive information on the charging and discharging states of the respective battery packs 320 through the cable 310 and transmits battery control signals to the battery packs 320 Can be transmitted. The configuration of the cable 310, the connection with each battery pack 320, and the communication protocol between the battery pack 320 and the controller 22 are well known to those skilled in the art or known in the art The system can be implemented in various systems or methods. 8, each of the battery packs 320 is shown as a cable, but the present invention is not limited thereto.
