Shell, power battery assembly and electric vehicle

Abstract

The invention discloses a shell, a power battery assembly and an electric vehicle. The shell comprises a mounting shell, separation pieces, a heat conduction layer, a liquid inlet and a liquid outlet,wherein a mounting groove is formed in the mounting shell and used for mounting materials, a plurality of first heat exchange channels arranged at intervals in the vertical direction are formed in the side wall of the mounting shell, the separation pieces are arranged on the bottom wall of the mounting groove, a plurality of second heat exchange channels arranged at intervals in the vertical direction are formed in the partition pieces, each second heat exchange channel communicates with one first heat exchange channel, a heat exchange liquid is introduced into the first heat exchange channels and the second heat exchange channels, the number of the separation pieces is multiple, the plurality of separation pieces are distributed at intervals along the length direction of the mounting shell, the heat conduction layer is arranged on the side wall of the separation piece, the liquid inlet is formed in one end of the mounting shell, the liquid outlet is formed in the mounting shell, anda closed structure is arranged in the mounting shell to block the multiple first heat exchange channels between the liquid outlet and the liquid inlet. According to the shell, heat exchange of materials in the shell can be achieved, and the space utilization rate in the shell is increased.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a housing, a power battery assembly and an electric vehicle. Background technique [0002] New energy vehicles have the advantages of high energy efficiency, zero emissions, no pollution, high specific energy, low noise, and high reliability, and have very broad development prospects. As the main energy storage component of the new energy battery vehicle, the power battery system mainly ensures the vehicle's low-speed driving, braking energy recovery, hybrid engine system energy regulation and other functions. As a core component, the power battery assembly is of great importance. In the prior art, the battery assembly layout mostly adopts the aluminum alloy profile welding scheme or the sheet metal stamping welding scheme. The above two layout schemes usually require a separate arrangement of the battery liquid cooling structure, which makes the structure of the power...

Problems solved by technology

In the prior art, the battery assembly layout mostly adopts the aluminum alloy profile welding scheme or the sheet metal stamping welding scheme. The above two layout schemes usually require a separate arrangement of the battery liquid cooling structure, which makes the structure of the power battery assembly more complicated. At the same time, the interior of the battery assembly The space utilization rate is not high, resulting in a short battery life of the assembly
