Embodiment Construction
[0032] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:
[0033] 1. Such as figure 1 , figure 2 , Figure 4 , Figure 5 As shown, the battery pack: consists of the box body 1, the lithium battery unit 4 and the protective plate 8 arranged inside the box body 1, the flexible upper cover 2 and the pressure plate 3 arranged on the upper part of the box body 1, and the cut-off plate arranged at the lower part of the box body 1. The valve 9 is composed of; the flexible upper cover 2 and the pressure plate 3 are fixed on the flange 105 of the box body 1 by screws and nuts, so that the inside forms an airtight structure; Assemble the watertight connector of the communication port to the corresponding interface screw holes 110, 111, 112, 113 of the box body 1, open the stop valve 9, and inject the silicone oil 11 into the box body 1 with a pump. The amount of silicone oil injected is according to the...

The invention discloses a novel pressure resisting polymer lithium battery pack for an underwater vehicle. The novel pressure resisting polymer lithium battery pack is capable of operating in any ocean depth. The novel pressure resisting polymer lithium battery pack comprises a box body, a lithium battery unit arranged in the box body, a protecting plate arranged in the box body, a flexible roof cover arranged on the upper portion of the box body, a pressing plate arranged on the upper portion of the box body and a stop valve arranged on the lower portion of the box body. The lithium battery unit is composed of a polymer monomer lithium battery, a PCB adapter plate and a supporting frame. The lithium battery unit and the protecting plate are fixed on the studs arranged on the box body through screws. A circuit connection between the protecting plate and the lithium battery unit is achieved through wires. The flexible roof cover and the pressing plate are fixed on flange edges arranged on the box body through the screws and nuts, so that a sealed structure is formed inside the box body. When the underwater vehicle submerges, the flexible roof cover automatic caves inwards so that pre-filled silicone oil in the box body can be compressed to generate the internal pressure, the dynamic equilibrium of the internal pressure and the external pressure of the box body can be achieved instantly, and therefore the situation that the box body is damaged by crushing, and water enters the box body can be avoided. The pressure resisting novel polymer lithium battery pack has the advantages that the safety is high, the reliability is high, the cost is low, and the application method is flexible.
Description
technical field [0001] The invention belongs to the field of lithium batteries, in particular to a novel voltage-resistant polymer lithium battery pack for a submarine. Background technique [0002] Due to the particularity of the field of use of submarines, batteries are destined to be the only power. Payload capacity and cruising time are important indicators to measure the performance of a submarine. [0003] In the past, silver-zinc secondary batteries were mostly used as power sources for underwater equipment, and their service life was only more than 30 times, and there were defects such as high maintenance costs and inability to use them at large inclination angles. In recent years, because polymer lithium batteries have high specific power, large specific energy, long cycle life, good safety, wide operating temperature range, good environmental adaptability (high temperature resistance, high humidity, high salt environment), easy maintenance and installation , and ...
