Abstract

The invention relates to a high-energy-density power battery pack integrated structure and a new energy automobile. The high-energy-density power battery pack integrated structure comprises a water-cooling integrated box body, a battery cell structure, a battery management system and a battery system distribution box, wherein the water-cooling integrated box body comprises a lower box body structure and an upper box body cover covering the lower box body structure, and a battery cell accommodating cavity is defined between the lower box body structure and the upper box body cover; the batterycell structure comprises a plurality of single battery cells arranged in the battery cell accommodating cavity, and a busbar structure electrically connected with the plurality of single battery cells; the battery management system is arranged at the end part of the water-cooling integrated box body and is electrically connected with the single battery cells through a sampling line structure; andthe battery system distribution box is arranged at the end part of the water-cooling integrated box body, corresponds to the battery management system up and down, and is electrically connected with the single battery cells through a busbar structure. According to the invention, the problems of low grouping efficiency, complex structure, low integration level, high cost and complex production andprocessing of the module integrated battery pack in the prior art can be solved.

Description

Technical field[0001]The invention relates to the technical field of new energy power batteries, in particular to a high-energy density power battery pack integrated structure and new energy vehicles.Background technique[0002]At present, the country is vigorously developing new energy vehicles, and the use of new energy power batteries is increasing. Moreover, in related technologies, new energy power batteries mostly use cells (Cell) to be integrated into a module (Model), and then the module is integrated into a battery pack (Pack) to form a module-integrated battery pack. However, this traditional module integrated battery pack has low grouping efficiency, complex structure, low integration, high cost, and complex production and processing.Summary of the invention[0003]The present invention provides a high-energy density power battery pack integrated structure and a new energy vehicle to solve the problems of low group efficiency, complex structure, low integration, high cost, an...
