[0025] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0026] Please see Figures 1 to 3 A highly versatile full-ocean-depth battery 10 includes: a battery casing 100 and a battery module 200. The battery casing 100 includes a cover 110, a bladder assembly 120, a valve assembly 130, and a housing 140. The bladder assembly 120 and the cover 110 are sequentially fixed on the top of the housing 140. The valve assembly 130 is disposed on the bladder assembly 120. An oil filling port 141 is provided on one side of the housing 140. The battery module 200 is disposed inside the battery casing 100. The battery module 200 includes multiple battery components 210, which are electrically connected to each other.

[0027] It should be noted that by sequentially fixing the bladder assembly 120 and the cover 110 to the top of the housing 140 using fasteners, the battery casing 100 forms a sealed structure. The housing 140 is made of titanium alloy, giving it high corrosion resistance. An oil inlet 141 is provided on one side of the housing 140, and a sealing ring is installed on the inlet 141. The sealing ring is fixed to the housing 140 with a nut, further improving the sealing performance of the battery casing 100. Oil is filled into the battery casing 100 through the oil inlet 141, giving the battery a pressure self-compensation structure, thus ensuring the battery's performance. In the field of deep-sea exploration technology, the air valve assembly 130 is set on the bladder assembly 120. When oil is filled into the battery casing 100 through the oil inlet 141, the air valve assembly 130 is opened to allow the air inside the battery casing 100 to be discharged, which facilitates the filling oil to fill the inside of the housing 140 and avoids insufficient filling oil, which would affect the pressure self-compensation effect. By splitting the battery module 200 into multiple identical battery components 210, users can adjust and combine multiple battery components 210 to achieve different voltage and capacity parameter settings, meet the energy needs of various complex deep-sea equipment, and improve the versatility of the battery for all ocean depths.

[0028] Please refer to it again. Figure 1 and Figure 2 In one embodiment, the bladder assembly 120 includes multiple bladder units 121, thereby dispersing the pressure of seawater on the battery casing 100 and improving the battery's pressure resistance. When the number of bladder units 121 is greater than two, the battery volume increases, which can easily affect the overall performance of the battery. Therefore, in this embodiment, it is preferable to install two bladder units 121, so that the battery has good pressure resistance without increasing its volume. The valve assembly 130 includes multiple valve units 131, each valve unit 131 is respectively disposed on each bladder unit 121, which is more conducive to the air inside the battery casing 100 being discharged to the outside, and the sealing oil is more evenly distributed inside the battery casing 100.

[0029] Please refer to it again. Figure 1 In one embodiment, the battery casing 100 includes a plurality of upper baffles 150, each upper baffle 150 being disposed above the cover 110. The upper baffles 150 are fixed to the cover 110 by using nuts, making the connection structure between the upper baffles 150 and the cover 110 more stable. The upper baffles 150 are mainly used to protect the bladder assembly 120 and prevent the bladder assembly 120 from being scratched by debris in the seawater. The upper baffles 150 are evenly provided with a plurality of through holes, which facilitates the contact between seawater and the bladder unit 121.

[0030] Please refer to it again. Figure 1 and Figure 2In one embodiment, the housing 140 has a battery discharge port 142 and a battery charging port 143, which are located above the oil filling port 141. This makes the housing 140 compact and facilitates the wiring arrangement between the battery module 200 and the battery discharge port 142 and battery charging port 143, thereby effectively increasing the capacity of the battery casing 100 and allowing for the installation of larger battery modules 200. This improves the overall energy density of the battery. Each component is equipped with a watertight connector 160. The watertight connector 160 is mainly used to ensure the sealing of electrical connections in an underwater environment, preventing water intrusion and ensuring the normal transmission of signals and electrical energy. This avoids the loss of the battery's charging and discharging function when underwater. The watertight connector 160 includes a sealing ring, which further improves the sealing effect of the battery. The watertight connector 160 is fixed to the battery discharge port 142 and the battery charging port 143 respectively by nuts, so that the watertight connector 160 is firmly connected to the battery discharge port 142 and the battery charging port 143.

[0031] Please refer to it again. Figure 2 In one embodiment, the bottom of the housing 140 is provided with a plurality of fixing brackets 144, so that the battery can be fixed on the deep-sea equipment through the fixing brackets 144, thereby preventing the battery from colliding with other equipment of the deep-sea equipment and affecting the sealing performance of the battery.

[0032] Please refer to it again. Figure 3 In one embodiment, the battery assembly 210 includes a cell housing 211, multiple individual cells 212, and two busbars 213. The cell housing 211 is made of aluminum alloy and undergoes hard anodizing and powder coating processes to improve its resistance to oil and seawater corrosion, providing excellent insulation performance. This ensures adequate protection for the individual cells 212 within the cell housing 211. The individual cells 212 are stacked within the cell housing 211, avoiding gaps between them and maximizing the utilization of the internal space of the battery casing 100, allowing for the installation of more... Based on actual installation results, 210 battery cells 212 can be installed in the battery casing 100. The battery cells 212 adopt lithium iron phosphate system batteries. Lithium iron phosphate system batteries have high energy density, which enables the battery to have a maximum output voltage of 500V and a maximum output current of 100A, meeting the maximum output power of 30KW, thus enabling the battery to have high power output capability. Two busbars 213 are connected to both sides of each battery cell 212 respectively. The two side tabs of the battery cell 212 are fixedly connected to the busbars 213 by laser welding, thereby realizing the series and parallel connection between the battery modules 210.

[0033] Please refer to it again. Figure 3 In one embodiment, the battery assembly 210 further includes two insulating plates 214. The insulating plates 214 are disposed on the side of the busbar 213 away from the individual cell 212. The insulating plates 214 are connected to the tabs of the individual cell 212, so that the individual cell 212 is electrically isolated from the external environment of the battery assembly 210, thus protecting the individual cell 212. Fiberglass is used as the insulating plate 214. Fiberglass has high insulation and compressive strength, so that the insulating plate 214 can withstand the pressure of seawater while providing electrical isolation for the individual cell 212, thereby improving the strength of the battery and making the battery more suitable for deep-sea environments.

[0034] Please refer to it again. Figure 1 In one embodiment, the system further includes multiple circuit protection boards 170, the number of which is the same as the number of battery components 210. Each circuit protection board 170 is disposed above each battery component 210, and each battery component 210 is connected to the circuit protection board 170 above it. The circuit protection board 170 is used to provide short-circuit protection and overcurrent protection for the battery components 210, thereby improving the battery's service life.

[0035] Please refer to it again. Figure 1 In one embodiment, a main circuit fuse 180 is also included. The main circuit fuse 180 is disposed on the side of the battery module 200 near the battery casing 100. The main circuit fuse 180 is used to provide short circuit protection and charging overcurrent protection for the entire battery module 200, thereby further improving the battery's service life.

[0036] Please see Figure 4 A battery connection structure includes the aforementioned highly versatile full-ocean-depth battery, with multiple full-ocean-depth batteries 10 electrically connected. Multiple batteries can be combined for use in complex operating environments, improving the battery's expandability underwater. Since the battery discharge port 142 and battery charging port 143 are located on the same side of the battery, it is convenient to combine the batteries for use.
