Abstract

The pulsed current charging technique has been proposed to improve the charging performance and lifetime of Lithium-ion batteries. However, the optimal operating conditions of the pulsed current, e.g., profile, frequency, duty cycle, and amplitude, still need to be investigated. This work focuses on investigating the effect on the lifetime of Lithium-ion battery cells of the positive pulsed current (PPC) in the low-frequency range between 0.05 Hz and 1 Hz. According to the results of cycling aging tests, the PPC charging at 0.05 Hz can extend the lifetime up to 60% compared with the traditional constant current (CC) charging. Furthermore, a lifetime model of the battery cell in terms of the capacity fade and the increase in internal resistance is developed to estimate the effect of the PPC charging at different frequencies on the lifetime of the Lithium-ion battery cells.
