Problems solved by technology
Lead-acid batteries have limited specific energy, large volume, relatively poor high-current discharge capacity and will produce gas; zinc-silver batteries have a short lifespan, and can only be used for 20 to 30 times at high power; lithium-ion batteries using organic electrolytes, When abnormalities such as overcharging or internal short circuit occur, the volatile and flammable organic electrolyte may cause thermal runaway. This problem is more prominent below the sea depth of 3000 meters, and the probability of safety incidents such as explosions increases.
[0004] In addition, the conventional power supply system is customized according to the power consumption of the deep-sea submersible, the design time is long, the degree of modularization is not high, it is not convenient for mass production, and the cost is high. energy interface, poor scalability

The invention provides a power supply system applied to a bathyscaphe. The power supply system provides electricity for the bathyscaphe through watertight cables and comprises vacuum glass floating balls which are packaged in a solid lithium battery pack, the vacuum glass floating ball comprises a main glass floating ball and sub glass floating balls, and the sub glass floating balls are connectedwith the main glass floating ball and the bathyscaphe in sequence through the watertight cables. The power supply system adopts a modularization design, energy can be expanded simply without the needof changing original equipment, it is unnecessary to dismount a cabin to replace batteries during energy supplement, charging can be conducted directly, and thus usage and maintenance are convenient;due to the underwater quality, the power supply system has the advantages of meeting requirements of the bathyscaphe for long endurance and high safety.
Description
technical field [0001] The invention relates to the technical field of power supply for underwater submersibles, in particular to a power supply system applied to deep-sea submersibles. Background technique [0002] The power system is the heart of a deep-sea submersible and one of the important indicators to measure the superiority of a deep-sea submersible. The power system used by deep-sea submersibles is usually a dry-type metal pressure-resistant cabin power system or an oil-filled pressure-compensated power system. For a dry-type metal pressure-resistant cabin power system, the battery pack is placed in the pressure-resistant cabin. As the depth increases, the thickness of the pressure chamber must increase, which will inevitably reduce the buoyancy of the submersible, thereby reducing the carrying capacity of the submersible. In the oil-filled pressure-compensated power supply system, the battery pack is directly immersed in oil. Under the influence of high pressure ...
