In the majority of applications using lithium-ion batteries, batteries are exposed to some\nharmonic content apart from the main charging/discharging current. The understanding of the effects\nthat alternating currents have on batteries requires specific characterization methods and accurate\nmeasurement equipment. The lack of commercial battery testers with high alternating current\ncapability simultaneously to the ability of operating at frequencies above 200 Hz, led to the design of\nthe presented experimental setup. Additionally, the experimental setup expands the state-of-the-art\nof lithium-ion batteries testers by incorporating relevant lithium-ion battery cell characterization\nroutines, namely hybrid pulse power current, incremental capacity analysis and galvanic intermittent\ntitration technique. In this paper the hardware and the measurement capabilities of the experimental\nsetup are presented. Moreover, the measurements errors due to the setupâ??s instruments were analysed\nto ensure lithium-ion batteries cell characterization quality. Finally, this paper presents preliminary\nresults of capacity fade tests where 28 Ah cells were cycled with and without the injection of 21 A\nalternating at 1 kHz. Up to 300 cycles, no significant fade in cell capacity may be measured, meaning\nthat alternating currents may not be as harmful for lithium-ion batteries as considered so far.
