A lithium battery pack protection device for underwater vehicle

Abstract

A lithium battery pack protection device for underwater vehicle includes a box, At the periphery of the box body, an external reinforce frame is coated, At the bottom end of the external reinforce frame, a mounting seat is arranged, A seal cover plate is slidably connected with that top end of the box body, A pressure-resistant shell is arranged on the inner wall of the box body, A first clampinggroove is symmetrically provided on the inside of the pressure-resistant housing, At one end of that lead pipe, the first clamping groove is connecte, At that other end of the conductor tube, a conductor connector is pas through the box body and fixed, one side of the conductor connector is provide with a first communication interface, the other side of the conductor connector is provided with a second communication interface, a lithium battery pack mounting cavity is arranged between the conductor tube, and a fixing plate is arranged at one side of the lithium battery pack mounting cavity; The conductor of the lithium battery pack is connected with the conductor connector through the through hole and the conductor pipe through the conductor pipe and the conductor connector, so that the wires in the battery pack are arranged in an orderly manner, the structural stability of the battery pack is improved, and looseness at the connector is not easy to occur.

Description

technical field [0001] The invention relates to the technical field of submarine equipment, in particular to a protection device for a lithium battery pack for an underwater vehicle. Background technique [0002] Submersibles are an important platform for underwater operations, and advanced energy technology is the key technology that determines their endurance and speed, and is an important indicator to measure the performance of submarines. In the history of the development of submarines, batteries have grown up with them all the way. Compared with traditional batteries such as lead-acid batteries, cadmium-nickel batteries, and zinc-silver secondary batteries, lithium-ion batteries have high energy density, long life, high safety, With the advantages of low cost and maintenance-free, it has become one of the most promising energy technologies for deep-sea manned submersibles. Due to the particularity of the environment in which the submersible is used, the battery has bec...

AI Technical Summary

Problems solved by technology

At present, most submersibles use underwater batteries encapsulated in pressure-resistant shells for direct power supply, but the safety and stability of the battery pack are also greatly tested by vibrations and swings during the voyage.
