Problems solved by technology

[0003] Existing electric vehicles are based on the separate connection between the body and the battery pack. Compared with the usual electric vehicle structure, the power battery case and the body are developed separately as two independent systems, and the cells of the battery pack are all square or soft. In the package form, due to the limitation of the body structure or connection structure, the power battery pack housing is limited to a relatively narrow and compact range, which makes the battery layout space tight. Therefore, through the integration of the battery pack and the body function and sharing with the body function, Realizing the expansion of the layout space of the battery pack has become a problem that needs to be solved

Abstract

The invention discloses a battery pack integrated with vehicle body functions and a vehicle. A vehicle body framework is provided with a tray structure; a containing cavity is formed between the floor and the tray structure; the battery module consists of a plurality of battery cells and is arranged in the accommodating cavity; the air duct is provided with an air inlet and a battery air outlet, the battery air outlet is formed in the containing cavity, at least part of the air duct body is arranged in the containing cavity, and the air inlet is connected with a whole vehicle air conditioning system; the battery pack is integrated with the vehicle body, the arrangement space of the battery pack is increased, the battery pack and the seat cabin share the warm air system, so that the heat management system and the vehicle body function are highly integrated, the internal space of the battery pack is optimized, and the cost is reduced; the arrangement of internal and external wiring harnesses of the battery pack is reduced; the battery management system selects an electricity taking object as a battery cell containing thermal runaway, so that the battery cell within the electricity taking range is rapidly discharged, and the risk of thermal runaway is reduced.

Description

technical field [0001] The invention relates to the technical field of electric vehicle batteries, and in particular, to a battery pack and a vehicle that are functionally integrated with a vehicle body. Background technique [0002] At present, the development prospect of new energy vehicles is very broad. New energy vehicles have the advantages of high energy efficiency, zero emissions, no pollution, high specific energy, low noise, and high reliability. As the main energy storage component of the new energy battery vehicle, the power battery system mainly ensures the driving of the whole vehicle, the power demand of high and low voltage components, the recovery of braking energy, and the energy regulation of the hybrid engine system. [0003] Existing electric vehicles are based on the split connection between the body and the battery pack. Compared with the usual electric vehicle structure, the power battery shell and the body are developed separately as two independent...
