At present, energy is in short supply all over the world, and the environmental pollution problem is becoming more and more serious. Therefore, in order to alleviate the double pressure of environmental pollution and energy, new energy vehicles have been invented, among which electric vehicles have been widely developed. Clean energy utilization is urgent and important, and it is becoming a trend to replace fuel vehicles with electric vehicles. Battery is an important component of electric vehicle, and its correlation with vehicle performance is rather high. Lithium-ion battery has the advantages of high energy density and low self-discharge rate, and has gradually become the preferred battery for electric vehicles. Sensors used in electric vehicles mainly include sensors for detecting battery temperature, sensors for monitoring motor temperature and temperature sensors for battery cooling system. The performance and service life of lithium-ion batteries are greatly affected by temperature. In order to control the temperature of lithium battery, this paper studies its thermal management system. This paper discusses the significance of temperature control of lithium battery in electric vehicle, and puts forward the optimization measures of operation mechanism of lithium battery thermal management system.
