Problems solved by technology

The problems with the battery pack box with this structure are: since the heating equipment and refrigeration equipment are arranged outside the box, it is easy to generate noise, which affects the comfort of the riding environment, and when the heat exchange is performed with the inside of the box, the air The circulation path is long, and the temperature distribution inside the box is uneven, which makes the working environment temperature of the battery cells inconsistent, which will have a negative impact on the charging and discharging performance and life of the battery; due to the need for heat exchange inside and outside the box, it is easy to cause energy waste ;In addition, there is an air inlet and outlet on the box body. When the car is wading or the interior of the car is flooded, water may enter the box body through the air inlet and outlet, resulting in safety accidents.

Abstract

The invention discloses a battery pack box body and belongs to the technical field of new energy automobiles. The battery pack box body comprises a sealed box body, wherein the box body is separated into a heat exchange bin and a battery bunching bin which are communicated by a horizontal baffle; the heat exchange bin is internally provided with a refrigerating unit and a heating unit; a plurality of batteries are ranked in the battery bunching bin dispersively. The battery pack box body can ensure uniform internal temperature distribution of the box body, thereby effectively improving the energy source utilization ratio, reducing the noise transmitted outside, improving the waterproof performance, and further guaranteeing the safety of the battery pack.

Description

Technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a battery pack box. Background technique [0002] As the power source of new energy vehicles such as electric vehicles or hybrid vehicles, the performance of batteries plays a decisive role in the performance, safety and service life of the entire vehicle. Because the temperature will affect the performance of the battery, too low temperature will cause the performance of the whole vehicle to decline, and too high temperature may cause safety accidents. Especially in the cold winter, due to the low ambient temperature, it is easy to cause the battery's charge and discharge performance to deteriorate; in the hot summer, due to the high ambient temperature, and when the battery is used in the charge and discharge process and high temperature environment, a large amount of release The heat of the battery is affected by the limited space of the vehicle, and it is easy to gene...
