With the rapid increase in environmental pollution over time, the climate change has progressed rapidly, and emissions of CO₂, CH₄, N₂O, HFCs, PFCs, and SF<SUB>6</SUB> are regulated. Several factors that contribute to climate change have happened in the fields of production and means of transportation, such as ships, planes, and cars. Owing to the strengthening of international regulations, there is a great deal of interest and investment in eco-friendly transportation around the world. An electric vehicle(EV), a representative model of eco-friendly transportation, has a battery, inverter, and electric motor system. Because the main source of energy for these eco-friendly means of transportation is a battery, it is important to create an environment that can increase battery efficiency and optimize battery lifetime so that the battery can be used for a long time. The internal resistance (IR) value of the battery, which can predict the lifetime characteristics, increases owing to harmonics, ambient temperature, and chemical reactions during charge/discharge. This study analyzed the battery lifetime based on the inverter driving pulse, which affects the motor current harmonic characteristics. It was verified that, as the dead time increased, the harmonic increased, and as the harmonic increased, the IR of the battery increased, affecting the lifetime of the battery.
