Abstract: The performance and cost of an electric vehicle depend to a large extent on the performance and service life of the power battery pack, while the performance and service life of the battery pack are affected by the heat generated by the battery unit. Studying the heat generation characteristics and influencing factors during the charging and discharging process of lithium ion batteries is of guiding significance for the development and use of lithium batteries. This paper begins with five aspects of ambient temperature, charge and discharge rate, battery material, nuclear power state and aging degree. The effects of various factors on the heat production of lithium ion batteries are reviewed.

Key words: review, lithium-ion batteries, charging and discharging, heat production
