Description

technical field

[0001] Embodiments of the present invention relate to the technical field of seabed energy, in particular to a deep-sea plug-in lithium battery power supply unit and system. Background technique

[0002] Deep-sea lithium battery is an important part of deep-sea equipment, which is used to provide essential energy supply for deep-sea equipment. The capacity of deep-sea lithium battery directly affects the operating efficiency of deep-sea equipment.

[0003] At present, most deep-sea lithium battery systems are installed in pressure tanks or in large-scale oil-filled battery boxes. When the pressure tank is installed, the volume and weight of the pressure tank are too large. As the depth increases, the weight and volume of the pressure tank increase rapidly, which affects the weight index of deep-sea equipment, thus affecting the snorkeling of deep-sea equipment. Performance; when a large-scale oil-filled battery box is installed, the battery capacity cannot b...
