Problems solved by technology

The main measure to ensure the safety of the battery pack is to keep the battery cells in a suitable temperature environment. Therefore, high requirements are placed on the cooling system of the battery pack. At present, the lower shell of the battery pack and the cooling system are independent of each other, resulting in a relatively heavy overall weight of the battery pack. In addition, the cooling system also uses heat conduction pads to cool the cells, and the cooling efficiency is low.

Abstract

The invention discloses a battery pack and a vehicle with the battery pack. The battery pack includes: a frame; a tray, the tray is installed on the frame; a battery module, the battery module is installed on the frame and / or the tray, and the battery module is located on the tray Above, a medium channel is formed between the battery module and the tray. According to the battery pack of the present invention, the battery module is in direct contact with the fluid medium in the medium channel, which can realize the direct transfer of heat between the fluid medium and the battery module, which is conducive to improving the heat transfer efficiency. At the same time, the medium channel is integrated into the battery Inside the pack, the connection parts are reduced, which is beneficial to reduce the overall weight of the battery pack.

Description

technical field [0001] The present invention relates to the field of automobiles, and in particular, to a battery pack and a vehicle having the battery pack. Background technique [0002] With the continuous development of electric vehicles, higher requirements are placed on the safety of battery packs. The main measure to ensure the safety of the battery pack is to keep the cells in a suitable temperature environment. Therefore, high requirements are placed on the cooling system of the battery pack. At present, the lower casing of the battery pack and the cooling system are independent of each other, resulting in a relatively heavy overall weight of the battery pack. In addition, the cooling system also adopts the method of heat transfer through the thermal pad to cool the cells, and the cooling efficiency is low. SUMMARY OF THE INVENTION [0003] In view of this, the present invention aims to provide a battery pack in which the battery module is in direct contact with t...
