In this paper, the effect of fast-charging technics on thermal behavior of lithium-ion batteries is investigated. Fast-charging tests involve typically high-current profiles which leads to high cell temperature increase, and thus in some cases thermal runaways. Most papers in literature present the fast-charging technic from an electrical point-of-view. The thermal aspect is often disregarded. Therefore, two charging profiles that are commonly used for fast-charging applications are applied on two lithium-ion chemistries: lithium nickel manganese cobalt oxide (NMC) and lithium titanate (LTO). Thermal pictures of the cells during the profile are recorded to witness the temperature distribution. In addition, to enlarge the study scope, three environmental temperatures are tested: 25°C, 10°C and 45°C.
