AI Customer ServiceIn , the effect of current rate on the aging is analyzed cycling the battery at different current rates. Anyway, even if the tests are performed in a climatic chamber at 25 °C, the temperature of the battery cell is not controlled and will change with the current rate due to its internal losses.
The current rate directly influences the battery temperature due to losses inside the battery. In particular, high charging/discharging currents imply a significant increasing of the battery temperature.
This paper documents an experimental investigation that studies the long-term impact of current ripple on battery performance degradation. Initial results highlight that both capacity fade and impedance rise progressively increase as the frequency of the superimposed AC current increases.
This applies in particular for EV batteries with an expected lifetime of more than ten years. This study investigates the influence of alternating current (ac) profiles on the lifetime of lithium-ion batteries. High-energy battery cells were tested for more than 1500 equivalent full cycles to practically check the influence of current ripples.
Current dependency of cycle aging of lithium ion battery. Thermal and current effects decoupled on cycle aging. Constant battery temperature during cycle aging at different cycle currents using Peltier cells.
In the literature, only a few papers have considered battery aging as a function of the charge/discharge current rate, but they agree that a higher current rate leads to faster battery aging. In any case, all of the tests have been conducted in a climactic chamber with a constant room temperature.
