Technical Field

[0001] This utility model relates to the field of marine technology, specifically to a marine power battery pack system. Background Technology

[0002] Currently, in ship electrical systems, the common approach to reducing fuel consumption is to use shaft-driven generators to supply power to the ship's electrical grid. However, shaft-driven generators are affected by the main engine. If the main engine fails or slows down, the shaft-driven generator will stop, leading to the risk of a power outage for the entire ship. Therefore, it is necessary to provide power backup for the main engine. Utility Model Content

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0019] See Figure 1-2A marine power battery pack system includes a battery support frame, battery pack components 2, a central control box 3, and a cooling system 4. The battery support frame is mainly composed of several multi-layered battery racks 1. The battery pack components 2 are placed inside the battery racks 1. The battery pack components 2 are electrically connected to the shaft generator grid through the central control box 3 for charging. The cooling system 4 cools the battery pack components. Specifically, the central control box 3 is externally connected to the shaft generator grid, which charges the battery pack components 2 as a backup power source. In the event of a main engine failure or speed reduction, the battery pack components supply power to the ship's system, ensuring normal navigation and ship safety. The shaft generator grid uses an 845kW permanent magnet through-shaft motor (shaft generator) with a lithium battery capacity of 967.68kWh. The shaft generator and battery system are connected to the grid through a centralized DC bus frequency converter control device.

[0020] See Figure 3 The battery rack 1 includes a base 11, a frame 12 mounted on the base 11, and multiple layers of placement plates 13 inside the frame 12, each layer of which is used to place battery pack assemblies. Fixtures 14 with mounting holes are located on the left and right sides of the front of the frame 12. Longitudinal beams 15 and transverse beams 16 are located on the left and right sides of the frame 12, and triangular supports 17 are provided between the longitudinal beams 14 and transverse beams 16, and between the transverse beams 16 and the frame 12. The battery rack 1 is a standard four-layer battery rack. The frame 12, placement plates 13, fixation pieces 14, longitudinal beams 15, transverse beams 16, and triangular supports 17 are assembled by bolts or welding. Standard customized battery pack assemblies 2 are then placed on the placement plates 13 and connected by cables. The triangular supports 17 are used to improve the overall strength and stability of the battery rack.

[0021] See Figure 4 The battery pack assembly 2 includes a housing 21, inside which a battery pack (not shown) is housed. Connectors 22 are located on the left and right sides of the front of the housing 21, and these connectors 22 cooperate with fixing members 14. Positive and negative power interfaces 23 and a communication interface 24 are located on the front of the housing 21. Clip-on members 25 are located on the left and right side walls of the housing 21 and are hung on a crossbeam 16. After the battery pack assembly 2 is placed on the placement plate 13, the connectors 22 and fixing members 14 overlap and are fixed together with bolts. Simultaneously, the clip-on members 25 are snapped into the outside of the crossbeam 16 for fixation, supporting the battery pack assembly 2 and reducing the pressure on the placement plate 13.

[0022] See Figure 1-2The cooling system 4 includes a liquid cooler unit 41, an inlet pipe 42, and an outlet pipe 43. The inlet and outlet of the cooler unit 41 are connected to the inlet pipe 42 and the outlet pipe 43, respectively. The inlet pipe 42 and the outlet pipe 43 are connected end-to-end and both cover the outside of the frame 12. Both the inlet pipe 42 and the outlet pipe 43 are provided with branch pipes 44, which are located at the connection between the battery racks 1. Cooling pipes 45 are installed on the branch pipes 44 and extend into the battery pack assembly 2. The cooling water generated by the liquid cooler unit 41 enters the inlet pipe 42 and the outlet pipe 43 in sequence to form a circulation. At the same time, the coolant enters the branch pipe 44 and the cooling pipe 45. The cooling pipe 45 delivers the coolant to the battery pack assembly 2 to cool it down, thereby improving the stability and safety of the system.

[0023] In summary, this utility model has the following system functions:

[0024] 1. PTO mode: The hybrid power system in navigation conditions can supply power to the daily load independently or operate in parallel with the auxiliary generator set for a long time;

[0025] 2. Main unit speed fluctuation suppression function: In PTO mode, the fluctuation of the main unit speed can be smoothed by charging and discharging the battery. This function can be activated or stopped by manual switch.

[0026] 3. Blackout prevention function: When the shaft generator / auxiliary machine fails or the main engine slows down, this battery pack system can discharge instantaneously to maintain grid operation until the backup auxiliary generator set starts.

[0027] 4. Under parking conditions, the battery has peak shaving and valley filling functions. When the auxiliary machine load rate is low and the battery SOC is below the upper limit, the auxiliary machine can charge the battery. When a large load starts, the battery can discharge to avoid frequent starting of the auxiliary machine.
