Abstract

The invention discloses a battery thermal management system for a vehicle. The battery thermal management system comprises a battery cooling assembly including a connecting section, a first heat exchange section for cooling a battery, and a second heat exchange section for cooling through an air conditioner on a vehicle. The first heat exchange section is suitable for being arranged inside the battery, the second heat exchange section is suitable for being arranged outside the battery, and the first heat exchange section is connected with the second heat exchange section through the connectingsection. According to the battery thermal management system, the cooling efficiency of the battery module is high; meanwhile, the battery thermal management system also has a function of heating thebattery module.

Description

Technical field [0001] The present invention relates to the field of vehicle technology, in particular to a battery thermal management system for a vehicle and a vehicle. Background technique [0002] With the development of electric vehicles, the thermal management of the battery directly affects the performance of the battery pack, thereby affecting the range of the electric vehicle. At present, the thermal management methods of electric vehicle battery packs mainly include air-cooled heat management and liquid-cooled heat management. Usually, the air-cooled cooling effect is not ideal, and the liquid-cooled thermal management system requires an additional cooling system, which is less energy efficient. Summary of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, an object of the present invention is to provide a battery thermal management system for a vehicle, which has high cooling efficie...
