Battery pack and vehicle

Abstract

The invention discloses a battery pack and a vehicle. The battery pack comprises a shell, an upper cover, a bottom cover and a cooling plate assembly, wherein the shell is divided into an upper shell part and a lower shell part by a partition plate, a first mounting space is formed in the upper shell part, a second mounting space is formed in the lower shell part, a first battery module is mounted in the first mounting space, and the upper cover is suitable for covering the first mounting space; a second battery module is mounted in the second mounting space, and the bottom cover is suitable for covering the second mounting space; the partition plate is internally provided with a slot for entrance from the outside of the shell; and a cooling channel is arranged in the cooling plate assembly, the cooling channel is provided with a liquid inlet and a liquid outlet, and the cooling plate assembly is arranged in the slot in a matched mode. According to the battery pack disclosed by the invention, the shell is divided into the upper shell part and the lower shell part by the partition plate, and the slot matched with the cooling plate assembly is formed in the partition plate, so that the reliability and the safety of the battery pack can be improved, the electric energy capacity of the battery pack can be increased, the overall structure of the battery pack is optimized, and the cost is saved.

Description

technical field [0001] The present invention relates to the technical field of power batteries, in particular, to a battery pack and a vehicle. Background technique [0002] Power batteries are an important part of hybrid vehicles and pure electric vehicles. The charging and discharging process of the power battery will generate a lot of heat. In order to make the power battery work at a suitable temperature, a cooling device through air cooling or liquid cooling is usually installed in the battery pack, especially the liquid cooling device is more common. However, if the coolant of the liquid cooling device in the battery pack leaks, it will cause problems such as a short circuit of the power battery. In addition, the battery pack in the related art also has complex cooling device structure, complex installation structure, inconvenient maintenance, occupies effective space in the battery pack, and reduces the number of installed single batteries.
