The pulsed current has been proposed as a promising battery charging technique to improve the charging performance and maximize the lifetime for Lithium-ion (Li-ion) batteries. However, the effect of the pulsed current charging is inconclusive due to the changeable current mode and conditions. This paper systematically investigates the effect of various pulsed current charging modes, i.e., Positive Pulsed Current (PPC) mode, Pulsed Current-Constant Current (PCCC) mode, Negative Pulsed Current (NPC) mode, Alternating Pulsed Current (APC) mode, Sinusoidal-Ripple Current (SRC) mode, and Alternating Sinusoidal-Ripple Current (ASRC) mode on battery performance. Moreover, a comprehensive analysis of the frequency impact on the quality of the current mode is performed. The current modes in this work are evaluated considering the maximum rising temperature, discharging capacity, and charging speed according to experimental results. Furthermore, this work provides guidance for developing pulsed current charging strategies to satisfy future charging requirements.
