Abstract

A lithium ion battery pack device comprises a shell used for installing a battery module, a guide rail used for fixing the battery module and the battery module used for providing electric energy, and the guide rail is arranged in the shell; the battery module is arranged on the guide rail. The lithium ion battery pack provided by the invention can be used in a high-temperature environment (less than 80 DEG C), and the use temperature range is wide; the aerogel is coated on the contact surface of the protective shell and the battery module, and the heat conductivity coefficient of the aerogel is less than 0.02, so that the heat insulation performance of the structure is enhanced, and the temperature regulation of the battery pack can be realized; the single-sided aluminized film polyimide adhesive tape is adhered to the outer surface of the lithium ion battery pack, so that the heat reflectivity is greater than 0.95, and the heat radiation resistance of the battery pack is enhanced. The guide rail and the shell are integrally connected structurally, the mechanical property of the whole machine is improved, the lithium ion battery pack can work for not less than 1 hour under the working environment that the random vibration root-mean-square acceleration magnitude is 10.8 g and the vacuum degree is 1000 Pa, and energy not less than 15 kWh is provided.

Description

technical field [0001] The invention belongs to the technical field of lithium ion batteries, and in particular relates to a lithium ion battery pack device. Background technique [0002] Lithium-ion batteries have the advantages of high energy density, high operating voltage, good rate capability, wide operating temperature range, and long cycle life. With the continuous upgrading of weapons and equipment in my country's aerospace field, the demand for lithium-ion batteries is increasing, and the requirements for lithium-ion batteries are also getting higher and higher, not only requiring lithium-ion batteries to make progress in energy density, but also for lithium-ion batteries. Its use environment temperature and mechanical conditions put forward more stringent requirements. [0003] At present, the maximum operating temperature of the lithium-ion battery pack is 60°C. However, due to the limitations of some special application fields, the lithium-ion battery pack must a...
