Problems solved by technology

The current cooling system has water cooling and air cooling. In comparison, the effect of the water cooling system is better. However, due to the high working voltage and high current of the car, the battery case of the water cooling system must be crack-proof, leak-proof and insulated. Makes the structure of the battery shell more complex, not suitable for processing and production
The air-cooling system is relatively ineffective. The air-cooling system depends on the temperature. In summer, the temperature is even higher than 35°C, and the temperature of the battery surface will rise rapidly to above 35°C. The temperature of the surface also drops

Abstract

The invention provides a temperature control shell for a lithium battery pack. The shell comprises a shell body and a cover plate arranged at the opening of the shell body, the shell body comprises an external layer of the shell body and an internal layer of the shell body, and the external layer and the internal layer are connected with each other, thus forming a cavity. Phase change materials are filled into the cavity to control the temperature. The temperature control shell has good temperature control effect and simple structure.

Description

technical field [0001] The invention relates to a temperature-controlled shell of a lithium battery pack. Background technique [0002] With the development of science and technology and the progress of society, people's requirements for quality of life are getting higher and higher. Environmentally friendly lithium batteries have entered people's lives as power sources for vehicles, power tools for electric tools, car starters, and high-energy mobile power sources, and have been widely used and recognized by the world. Electric vehicles such as electric buses running on the road are greatly affected by the external temperature. In the case of high temperature in summer, the temperature is as high as 40°C, and the radiation temperature on the asphalt road is also as high as 55°C. When the electric bus is running, the battery Always in a state of high current discharge, it will also generate some heat. Due to the impact of the high temperature environment, the efficiency of...
