Abstract

The invention discloses a battery box which comprises a shell and a battery bucket, wherein the battery bucket is arranged inside the shell; a battery module is arranged inside the battery bucket; airchannels for heat radiation of a battery module is radiated are formed inside the shell; the air channels comprise multiple layers of the air channels formed in the depth direction of the battery bucket. Due to the design of the multiple layers of the air channels inside the battery box disclosed by the invention, the heat radiation effect and the heat radiation uniformity of the whole battery box are greatly improved, the working temperature of the whole battery box is controlled to be less than 55 DEG C, and safe operation of the battery box is ensured.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a battery box. Background technique [0002] In the past ten years, under the strong support of national policies and the stimulation of market demand, the new energy vehicle industry has flourished, and various types of electric vehicles have emerged in an endless stream. The on-board power battery system is the only source of power for pure electric vehicles, which directly determines the performance of the vehicle. Due to the limitation of the energy and voltage of single cells, the vehicle power battery must be composed of several or even hundreds of single cells in series and combined into a battery pack to form a power supply capable of outputting high voltage and high current. The battery pack will generate heat during operation and the temperature will rise, which will affect the performance and life of the battery. The existing battery box is also provided with a heat...
