Deep sea plug-in lithium battery power supply unit and system

Abstract

The invention discloses a deep sea plug-in lithium battery power supply unit, and a system, and belongs to the technical field of seabed energy. The deep sea plug-in lithium battery power supply unitcomprises a plug-in self-compensation cell box, compensation membrane, hydraulic oil, electrical hydraulic watertight connectors, a lithium battery, a battery management system, and a sensor; the lithium battery, the battery management system, and the sensor are arranged in the plug-in self-compensation cell box; the internal part of the plug-in self-compensation cell box is filled with hydraulicoil; the compensation membrane is fixedly arranged on the top end of the plug-in self-compensation cell box using press strips and bolts; the plug-in self-compensation cell box is provided with a swallowtail clamping groove, and a swallowtail clamping part; the lower part of the plug-in self-compensation cell box is provided with two electrical hydraulic watertight connectors. The deep sea plug-inlithium battery power supply unit is capable of solving problems in the prior art that deep sea lithium battery system weight is high and size is large, and maintenance and replacing are inconvenientafter damaging; the modularization degree of the deep sea lithium battery power system is increased, and maintenance and replacing are convenient.

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...

AI Technical Summary

Problems solved by technology

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 be freely combined, and it needs to be redesigned according to the needs of different deep-sea equipment, and it cannot be quickly replaced or repaired after damage
