Recycling high-efficiency heat-radiating battery device for electric vehicle

Abstract

The invention discloses a recycling high-efficiency heat-radiating battery device for electric vehicles. A plurality of symmetrically distributed single battery modules which are formed by sleeving single batteries into battery shells are arranged in a battery module box, phase change material is filled between the single batteries and the battery shells, gaskets are respectively arranged among the battery module box, flanges and the connecting parts of the single battery modules, the flanges and the single battery modules are fixedly connected with the battery module box by screws, both sides of the battery module box are respectively provided with a cooling liquid inlet and a cooling liquid outlet, liquid which flows from the cooling liquid inlet and the cooling liquid outlet is normal-temperature water in the battery module box, both ends of an electrode connecting pole are respectively connected with a battery anode and a battery cathode. The recycling high-efficiency heat-radiating battery device not only can effectively reduce the temperature of the whole battery device of an electric vehicle battery in a harsh thermal environment, but also can satisfy the temperature distribution balance among single batteries, is easy to recycle to achieve an optimal running condition, reduce cost and enhance economical efficiency.

Description

technical field [0001] The invention relates to a recycling high-efficiency heat dissipation electric vehicle battery device. Background technique [0002] Due to the increasingly prominent environmental problems and energy crisis, energy conservation and environmental protection must become an inevitable trend in the automotive industry. Electric vehicles are powered by power batteries, have no pollutant emissions, and are more economical than fuel vehicles, which will inevitably become the future development trend of the automotive industry. The key technologies restricting the development of electric vehicles are the improvement of battery performance and the recyclable utilization of battery devices. The internal material composition of the battery and the thermal management of the battery module are of great significance to the improvement of battery performance. The internal chemical reaction of the battery tends to generate a large amount of heat, which causes the t...

AI Technical Summary

Problems solved by technology

The internal chemical reaction of the battery tends to generate a large amount of heat, which causes the temperature of the battery to rise. Excessively high operating temperature will degrade the performance of the battery. If the heat accumulates quickly inside the battery without time to dissipate, the battery may leak, outgas, and smoke. In severe cases, the battery will burn violently and explode
