The article examines the impact of high temperature climatic factors on the operational safety of electric vehicle battery systems under the conditions of the Republic of Uzbekistan. It is shown that the prolonged periods of extremely high temperatures characteristic of the region, intense solar radiation, and heating of road infrastructure create a stable thermal load on traction battery systems that significantly differs from the conditions of a temperate climate. Temperature dependent mechanisms of degradation of lithium ion batteries and the specific features of emergency condition formation, including thermal runaway, ignition, and the release of toxic decomposition products, are analyzed. Particular attention is given to assessing risks to human safety and the environment in cases of battery system overheating in densely built urban areas and enclosed spaces. An analysis of the existing regulatory and legal framework has been carried out, demonstrating its limited adaptation to hot climate conditions and insufficient regulation of climate related risks. The discussion of the results confirms the necessity of developing climate adapted requirements and preventive measures aimed at increasing the level of safety in the operation of electric vehicles in regions with high ambient temperatures.
