Embodiment Construction

[0038] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0039] In the prior art, dozens or even hundreds of single square aluminum-case batteries are often loaded in the battery box, and the square aluminum-case batteries are often placed side by side in the box of the battery box. , due to internal resistance and other reasons, a large amount of heat will be generated, which is difficult to release into the environment, causing the temperature in the battery box to gradually rise, high temperature will shorten the service life of the battery and easily cause safety hazards, therefore, this application proposes a battery box , to enhance the heat dissipation performance of the battery box.

[0040] Please see Figure 1-Figure 4 , the present application proposes a battery box, comprising: a box body 1 ,...

Abstract

The invention provides a battery box and a vehicle, wherein the battery box comprises a box body; abattery module, wherein a plurality of battery molds are assembled in the box, and the battery moduleis provided with a battery; aheat pipe arranged in the battery module, the heat pipe being in contact with the housing of the battery for absorbing heat on the housing; The heat dissipation device isused for dissipating heat to the heat pipe, thereby improving the heat dissipation efficiency of the battery box, preventing the battery temperature from rising to affect the service life and causingpotential safety hazards.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a battery box and a vehicle. Background technique [0002] With the promulgation of national policies and the promotion of new energy vehicles, batteries, especially power batteries with higher specific energy, have attracted more and more attention. Designs such as battery box material selection, structural design, and cooling methods have also become the subject of current research. . [0003] Under different operating conditions of new energy vehicles, the battery system has a certain internal resistance, which will generate a certain amount of heat while outputting power and electric energy. It is easy to cause safety hazards. It is usually required to control the battery temperature below 55°C during the high-rate charging and discharging process to meet the service life of the battery under long-term working conditions and prevent danger caused by overheating. The battery box con...
