Abstract

The invention discloses a battery box and a vehicle with the same. The battery box comprises a box body, a battery module, a cooling orifice plate, an evaporator and an air circulating device, the battery module is arranged in the box body and is separated from the bottom wall of the box body, the cooling orifice plate is arranged between the battery module and the bottom wall and provided with cooling holes towards the bottom face of the battery module, the evaporator is disposed in the box body, the air circulating device is arranged in the box body and used for guiding air in the box body to the evaporator and outputting cold air formed after heat exchange of the evaporator to the cooling orifice plate, and accordingly the cold air is blown to the battery module through the cooling holes. By means of the arrangement of the cooling orifice plate, the evaporator and the air circulating device, the battery box can provide cold air for the battery module in the battery box, the cold air can bring away heat of the battery module, and the work temperature of the battery module can be quickly reduced.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a battery box and a vehicle with the battery box. Background technique [0002] In related technologies, pure electric vehicles, plug-in or hybrid electric vehicles all use a power battery system as the energy source of the vehicle. The operating temperature of the battery has a great influence on the battery capacity and cycle life. At present, most electric vehicles adopt the natural cooling method, relying on the battery pack case for heat dissipation, the heat dissipation effect is poor, and the heat accumulated in the battery pack cannot be quickly dissipated to the outside through the battery case, resulting in a high internal temperature rise of the battery pack , affecting the capacity and cycle life of the battery. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Fo...
