Popis: Battery electric vehicles (BEVs) are being considered as a replacement technology for diesel vehicles in underground mining of mineral resources. However, many issues related to BEVs in industrial applications still require more detailed research. One significant topic is the heat load—BEVs' heat emission into the working environment during regular operation. This paper provides an overview of the thermal behavior of NMC and LFP Li-ion cells tested under various conditions, which is an important step in determining the overall heat load of BEVs. The surface temperature of three NMC and one LFP 18650 Li-ion cells was monitored during charging and discharging at four different rates, at constant ambient temperatures of 30 °C and 40 °C. The main results pertain to the cell's thermal behavior during charging and discharging, highlighting the distinctive temperature profiles of NMC and LFP cells.
