New energy automobile lithium battery suitable for low temperature

The invention discloses a new energy automobile lithium battery suitable for low temperature. The new energy automobile lithium battery comprises a shell and mounting racks fixedly connected with theside walls of the two ends of the shell. The interior of the shell is divided into a battery cavity and a device cavity through a partition plate; a plurality of groups of lithium battery bodies are installed in the battery cavity, and a fixed screen plate is fixedly connected between the inner walls of the device cavity. According to the invention, a friction mechanism, a wind cup, a bar-shaped magnet and an iron pipe are arranged; during driving of an automobile, airflow can drive the wind cup to rotate, and therefore, a lower friction disc is driven to rotate; static electricity is generated by continuous friction with an upper friction disc; finally, an electrostatic sharp needle generates a point discharge phenomenon; the air in the device cavity is heated to expand and discharged into the battery cavity to w
