“…After 100th cycle, #A Cell shows exhibits a larger growth trend (about 18.8%) and increase of ohmic resistance than #B Cell (about 12.5%). However, for the #C Cell and #D Cell (cells under vibration test and static test), there is no apparent changes at 200 cycles for the ohmic resistance, which concludes that the ohmic resistance of the cells under vibration test and static test may be not subject to vibration stress (without aging stress) [28].…”

The battery degradation tests under various stress are critical to understand the relationship between the battery lifespan and the external factors. This paper establishes a battery test bench, which can provide not only the 6-six degree of freedom (DOF) vibration stress but also the charge-discharge stress. By conducting lithium-ion batteries under 6-DOF vibration stress and other reference experiments, the electrochemical impedance spectroscopy (EIS), internal resistances, thermal measurement, open circuit voltage (OCV) recovery and capacity of the cells are compared to determine the impact of the 6-DOF vibration stress on the cells. The experimental results show that the vibration stress increases the ohmic resistance, and also causes a higher heat release. In addition, the cells under vibration stress exhibit a higher capacity fade and a lower OCV recovery rate, while the internal impedance is also changed with vibration stress. In order to quantize the effect of the vibration stress on battery degradation, the analysis of variance (ANOVA) is calculated. The conclusion is that the vibration stress has little impact on the cell polarization resistance, while it significantly affects the ohmic resistance, OCV recovery, thermal measurement, and capacity of cells, respectively.INDEX TERMS Electric vehicle (EV), lithium-ion battery, six-degree-of-freedom (6-DOF) vibration stress, performance test, analysis of variance (ANOVA).

“…Abrupt acceleration and braking events require the battery pack and power converter to deliver an amount of current that depends directly on the acceleration [16]. Furthermore, in Lithium-based battery technology, current outputs above the rated 1-C current, lead to sharp changes on its internal resistance value, thus reducing its operational energy capacity [17]. To test this out, three constant acceleration profiles were designed and are presented in Fig.…”

“…Diffusion resistance (Rd), which is an equivalent of electrochemical reaction on surface of electrode, and capacitance of electric double layer (Cd) is used to accurately estimate parameters in xEV re-useable batteries. However, due to continuous charging and discharging, it is not easy to measure electrical parameters of batteries, and as aging of the battery accelerates by cause of high ambient temperature and high charging and discharging current, there is a limit to estimate the internal resistance [13]- [20]. Another method measures AC voltage by applying AC current on battery cell for 1~5 seconds at a frequency of 1.0±0.1kHz.…”

xEV batteries are not easy to accurately estimate and measure aging parameters for reuse due to continuous charging and discharging. In addition, existing AC-IR measurement methods require high-performance micro-controller units (MCUs) to handle complex operations for parametric estimation. As a cost-effective way to solve this problem, we propose AC-IR estimation techniques and implementation circuits to estimate internal battery parameters using AC ripple with DC offset wave in low and high frequencies. It estimates electrolyte resistance (Ri) by using band-pass filter (BPF) to extract AC components of a particular frequency voltage and current and by entering very high frequencies that have the effect of shorting the equivalent capacitance by the electrical double layer (Cd) of the Randls model. The charge transfer resistance (Rd) and electrical double layer capacitance (Cd) are estimated by Discrete Fourier transform (DFT), detecting effective and reactive current by inserting low frequencies. To realize the proposed approach, we propose analog power measurements and peak detection circuits, and a circuit configuration of converter supplying AC ripple with DC offset wave to estimate internal parameters at the same time to charge battery. To verify the feasibility and high-performance of the proposed AC-IR estimation method, we carry out PSIM simulations and experiments, and compare results with commercial battery parameter measuring instrument. As a result, we found that the error rate of the proposed method is lower than that of the commercial instrument as Ri is 0.24% and Rd is 1.18%, respectively.
