The most widely used and mature unmanned plane currently adopts lithium battery power supply. Due to the inherent chemical properties of lithium battery, the electrolyte of lithium battery unit condenses in low-temperature environment, the internal resistance is reduced, and lithium condensation is formed in the cathode, which has irreversible influence on the service life of the battery. At the same time, low temperature seriously reduces the performance of the battery, and high temperature can cause the battery to age quickly, shorten the service life, reduce the charging capacity of the battery, increase the release rate of electrolyte, and may cause the battery to melt or explode, causing serious safety accidents. In northeast China, machine inspection operation not only faces high-temperature environment in summer, but also faces serious low-temperature influence in winter. The average temperature in winter is-20℃, and the operating temperature of lithium battery is affected by the external environment due to the change of seasons. The best temperature is about 25℃ in summer and about 21℃ in winter. When the machine inspection operation is carried out outdoors, the temperature of the battery needs to be raised to above 21℃ during the process of moving from one machine inspection work point to another. Therefore, a proper temporary storage environment should be maintained during outdoor operation to prevent the battery temperature from being too high or too low, so as to ensure the normal service life of the battery.
