Nowadays, lithium-ion batteries regarded as secondary batteries of power sources are the most widely used in electric and hybrid vehicles because of their high energy densities. However, the secondary battery is being asked for a greater capacity and its application becomes more diverse, thus establishing technology to improve safety becomes an important issue. In this work, we performed the thermal analysis of a large-format prismatic lithium-ion battery based on the discharge profile for ISO cycle life tests, which includes load fluctuations during driving and regenerative charging.
