Abstract

The invention relates to the technical field of a lithium battery, in particular to a low-temperature self-heating and high-temperature heat-dissipation overcharge-overdischarge prevention winding-type lithium battery. The lithium battery comprises an anode, a cathode and an injection hole, and also comprises a heat dissipation window, a state display instrument, a battery shell, phase change layers, a control block, concentrators, a heating cylinder, a winding group and fans, wherein the heat dissipation window and the state display instrument are arranged on the side wall of the battery shell, the heat dissipation window is provided with a temperature sensor, the state display instrument is provided with a red alarming lamp and a green alarming lamp, the lower end of each concentrator is provided with a SOC sensor, the winding group is arranged inside the heating cylinder, two ends of the heating cylinder are provided with the fans, two ends of each fan are provided with the concentrators, and the phase change layer is arranged between each fan and the battery shell. The lithium battery is applicable to various temperature conditions, can perform self-heating at a low temperature, and can dissipate heat automatically at a high temperature, the overcharge and overdischarge of the battery can be prevented to protect the application performance of the battery and prolong the service life of the battery, and thus the lithium battery is a lithium ion battery with powerful functions.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a low-temperature self-heating, high-temperature heat dissipation, anti-overcharge and over-discharge wound lithium battery and a control method. Background technique [0002] With the development of science and technology, electric vehicles are becoming more and more popular, and the state also has various preferential policies for this. As the core key component of electric vehicles, batteries have a decisive impact on the driving performance of electric vehicles.
