Abstract

The invention provides a lithium-ion battery pack for an electric automobile. The lithium-ion battery pack comprises a battery pack box (1), a battery pack bottom plate (2) which is opposite to the battery pack box (1), multiple battery modules (3) arranged in the battery pack box (1), and a connector (6) arranged on the side surface of the battery pack box (1) and connected with the battery modules (3), wherein the multiple battery modules (3) consist of a plurality of battery cells (32). The interior of the battery pack and the interior of the battery modules (3) are filled with organic silicone (7), so that the interior structure is more reasonable, the shock resistance, waterproof and dustproof performances, battery module thermal field consistency and battery cell flame retardancy of the lithium-ion battery pack for the electric automobile are improved, and the service life of the battery pack is prolonged.

Description

technical field [0001] The invention relates to the technical field of lithium-ion batteries, in particular to a lithium-ion power battery pack for electric vehicles. Background technique [0002] As the concept of environmental protection is deeply rooted in the hearts of the people, pure electric vehicles, as a truly green and environmentally friendly vehicle, will surely become the future development trend of the automotive industry. For a long time, the development of electric vehicles has been limited by the two technical bottlenecks of high battery cost and short life. With the innovation and improvement of technology in recent years, battery technology has developed rapidly. Power batteries have also gradually developed from traditional lead-acid batteries to advanced green power batteries such as nickel-metal hydride batteries, lithium cobalt oxide, lithium manganese oxide, and lithium iron phosphate. However, although the performance of these new power lithium bat...
