High water-resistant thermal-insulation battery box for electric automobile

Abstract

The invention relates to the technical field of batteries of electric automobiles, specifically to a high water-resistant thermal-insulation battery box for an electric automobile. The battery box comprises a sealed box, a plurality of battery cells in the box and a radiator arranged in the box and connected with the plurality of battery cells, wherein each battery cell is provided with a heating device, and a battery box controller connected with the heating devices through a control circuit is arranged in the box. According to the invention, hollow heating radiating panels are arranged for heat radiation of each battery cell module, so uniform heat radiation of the battery cell modules is guaranteed, and heat radiation efficiency is improved. The heating devices are used for electric heating of the battery box when the battery box is in a low temperature state so as to guarantee reliable operation of a power lithium battery; through real time monitoring of heating plates, temperature homogeneity of a battery pack is guaranteed; the problems of heat radiation during working of batteries of an electric passenger car, heating during cold start-up and the like are overcome; and the battery box is safe and reliable and can be conveniently and rapidly dismounted.

Description

[0001] technical field [0002] The invention relates to the technical field of electric vehicle batteries, in particular to a highly waterproof and heat-retaining battery box for electric vehicles. Background technique [0003] With the progress and development of society, traditional energy sources are getting closer and closer to exhaustion, so it is imperative to develop new energy sources, including nuclear energy, solar energy, and combustible ice, which will be the trend of future energy technology development and will also become the future The source of power for the car. The rapid development of the transportation industry is the electrification of railway transportation. After the key development of the Eleventh Five-Year Plan, the electrification level of my country's railways has exceeded 80%, and the development of electric technology in automobiles is relatively slow. With the development and progress of battery technology, researchers have developed a new ty...
