Abstract

The present invention discloses a composite cooling thermal battery thermal management device. The device comprises a heat conduction cavity attached at the surface of a battery in a heat conduction mode, the top portion of the heat conduction cavity is divided into an air cavity and a liquid cavity by a perforated separator, the top portion of the air cavity communicates with a plurality of condensers and a cooling device used for cooling the condensers, and the liquid cavity contains a cooling liquid. The composite cooling thermal battery thermal management device disclosed in the inventioncan employ a mode of utilizing a plurality of cooling modes at the same time to perform fast cooling for the battery, balance the temperature differences of the internal portions of battery cells andbetween the battery cells, reduce the hot stack, prolong the service life of the battery and provide a good operating temperature environment for the battery cells.

Description

Technical field [0001] The invention relates to the field of electric vehicle batteries, in particular to a composite cooling thermal battery thermal management device. Background technique [0002] With the diversification of the automobile industry and the increasingly severe environmental problems, the new energy automobile industry is developing rapidly. Among them, electric vehicles have a smaller environmental impact than traditional vehicles and are used more and more widely. Electric vehicles are powered by on-board power supplies. , Use motors to drive wheels to drive vehicles that meet the requirements of road traffic and safety regulations. As the heart of electric vehicles, batteries are the key to the development of the electric vehicle industry. In addition to battery life, the bottleneck of the development of electric vehicles, battery safety issues It should not be underestimated. [0003] The battery management system is an important link between the vehicle power...
