Deep sea low temperature inverse control ocean observation battery compartment

Abstract

The invention belongs to the field of deep-sea low-temperature power supply for ocean observation, and in particular relates to a deep-sea low-temperature inverse control type ocean observation battery compartment. Based on the low-temperature observation environment in the deep sea, and the characteristics that the battery discharge capacity decreases with the temperature drop, using the characteristics of heat generation in the battery discharge process and periodicity in the observation process, through the design of temperature insulation, heat preservation, and accumulated temperature, these side effects are collected, protected, and accumulated. Combined with the optimal discharge cycle control of specific observations, it is applied to the deep-sea low-temperature reverse maintenance of the working discharge temperature of the battery; in order to maintain stability, an initial temperature control warming cabin is set; in order to ensure safety, limit temperature control and high-pressure through holes are set; At the same time, it integrates deep-sea anti-compression technology, watertight technology and full-filled anti-shaking fatigue technology. Make conventional battery packs work at a temperature close to the optimal discharge temperature under deep-sea low temperature conditions, increase the discharge capacity by 30%, significantly improve the efficiency of deep-sea observation and reduce observation costs, and guarantee the deep-sea strategy of Xianghaitu.

Description

technical field [0001] The invention belongs to the field of power supply for deep-sea low-temperature special environment for ocean observation, and in particular relates to a deep-sea low-temperature inverse control type ocean observation battery compartment. Background technique [0002] In recent years, with the rapid increase in population, the deterioration of the environment, and the gradual shortage of land resources, the research on the deep sea has attracted more and more attention from all walks of life. In order to better develop, utilize and protect marine resources and energy, it is necessary to obtain large-scale and accurate data of various marine parameters, and to conduct a large number of deep-sea observations of seabed-based and submerged buoys, which are inseparable from batteries to provide energy power. [0003] The temperature of seawater generally varies between -2°C and 30°C. Direct observations show that the ocean water temperature in the world g...
