“…LIBs are designed and operated under dc current principles [2], and for that reason traditionally ac currents have been recommended to be reduced by manufactures [3]. Therefore, the main LIB technological advances have been focusing essentially in dc current related features, like for instance life cycle or charge acceptance.…”

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

“…It is commonly established that ripple currents reduce the system reliability and the battery life time. As mentioned in [2], ripple currents are often recommended to be limited within specified levels. For this purpose, several techniques, including active or passive filtering design, have been developed to mitigate ripple currents, as exemplified in [3].…”

“…Additionally, it has been demonstrated in [5,6] that by charging a liion battery with a specified imposed current ripple, charging efficiency and lifetime expectancy can be improved. From [2][3][4][5][6], one can conclude that there are different perspectives, as well as different contexts that should be linked together, and questions that should be addressed with appropriate data. With this motivation, an experimental setup, allowing for testing the effect of ripple currents on li-ion battery cells, has been designed and is currently under construction in a joint project of KTH and Scania AB.…”

This paper describes an experimental setup for investigating the effects of current ripple on lithium-ion battery cells. The experimental setup is designed so that twelve li-ion cells can be simultaneously tested in a controlled environment. The experimental setup allows for a wide range of current ripple in terms of frequency and amplitude. Additionally, the quantification of the current ripple effects such as the aging of li-ion cells implies that a precise measurement system has to be designed which also are discussed in the paper.

An inherent zero-voltage and zero-current-switching phase-shifted full-bridge converter with reverse-blocking insulated-gate bipolar transistor (IGBT) or non-punch-through IGBT is proposed in this paper. This converter not only ensures that the switches in the lagging leg works at zero-current switching, but also minimizes circulating conduction loss without any additional auxiliary circuits. A 1.2 kW hardware prototype is designed, fabricated, and tested to verify the proposed topology. The control loop design procedures with small-signal models are also presented. A simple, low-cost, and robust democratic current-sharing circuit is also introduced and verified in this study. The proposed converter is a suitable alternative for compact, cost-effective applications with high-voltage input.
