Problems solved by technology

At present, zinc-silver batteries are usually used in the field of transportation, but due to the inherent characteristics of the zinc-silver battery system, poor wet shelf performance, short storage life, complicated operation, and inability to charge on arrows, etc., its use in the field of transportation is limited.
Faced with the long-term and high-power electricity demand of the upper stage, the designed zinc-silver battery has problems such as large volume and heavy weight. Therefore, a new battery pack design is urgently needed to meet the miniaturization and high power requirements of the upper stage.

Abstract

The present invention provides a lithium ion battery pack for an upper stage. The lithium ion battery pack comprises a shell, a battery cell stack, an insulation board, rubber pads, heat conduction silica gel and an electric connector, wherein the battery cell stack is arranged in the shell and comprises single batteries, adjusting sheets and bridging sheets; the single batteries are sequentiallyarranged in the transverse direction and the longitudinal direction, the adjusting sheets are arranged between the single batteries, and the single batteries are connected in series and in parallel through the bridging sheets; the rubber pads are arranged at the bottom of each single battery; heat conduction silica gel is coated between the single batteries and the rubber pads and between the single batteries and the adjusting sheets; the insulation board is arranged between the side wall plate of the shell and the battery cell stack, and the electric connector is arranged on the shell. According to the lithium ion storage battery disclosed by the invention, all electric energy required by load of the whole device can be provided for 48 hours in orbit from the time when the whole device atthe upper stage is converted into internal electricity to the time when the task at the upper stage is completed.

Description

technical field [0001] The invention belongs to the technical field of carrier power supplies, in particular to a lithium-ion battery pack for the upper stage. Background technique [0002] In recent years, with the continuous rapid development of lithium-ion battery technology, the application in the field of transportation in my country has gradually expanded. At present, zinc-silver batteries are usually used in the field of transportation, but due to the inherent characteristics of the zinc-silver battery system, poor wet shelf performance, short storage life, complicated operation, and inability to charge on arrows, etc., its use in the field of transportation is limited. . Facing the long-term and high-power electricity demand of the upper stage, the designed zinc-silver battery has problems such as large volume and heavy weight. Therefore, a new battery pack design is urgently needed to meet the miniaturization and high power requirements of the upper stage. Conten...
