Discharge characteristic analysis of lithium ion battery under full deep sea environment
In this paper,the discharge characteristics of the lithium-ion battery are analyzed according to the data of the battery's voltage,current,core temperature and SOC under full deep sea environment.By extracting the battery current and water temperature data,the core temperature characteristics along with the change of battery current and water temperature is analyzed,at the same time the different branch of the cell temperature change characteristics are analyzed,and combining with the characteristics of different latent time of battery current and water temperature,cell temperature changes in different stages.In addition,the influence of battery current on SOC is analyzed,and the characteristics of SOC changing with battery current under different dives are compared and analyzed.
