Experimental of Heat Generation on Electric Motorcycle NMC and LiFePO4 Battery Pack

The electric motorcycle is one type of transportation that is suitable for urban activities. Electric motorcycles use batteries as an energy storage component to store electrical energy. Lithium-ion batteries are generally used as the battery packs used in electric motorcycles. There are various types of lithium batteries that have different characteristics and performances. In general, electric motorcycle use batteries with small dimensions and have a high energy density such as the NMC type, or batteries with a high number of cycles such as the LiFePO4 type battery. The different batteries will produce different heat characteristics, with an optimal working temperature of 15-35 C. When the battery is used there will be an increase in temperature due to chemical reactions that occur in the battery cells. This paper will further discuss the characteristics of the battery pack when used at different temperatures in real use. The use of different types of batteries has different characteristics when facing an increase in temperature. NMC batteries have faster SOC reduction and higher heat generation compared to LFP.
