AI Customer ServiceThis 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.
The ripple of the charging current is pretty important for the aging of an electric battery. So, the current ripple should be as less as possible. In order to reduce the current ripple, we have to use bigger values of inductances (For instance in a boost converter). So, there is a takeover between current ripple and the value of L.
Cells 4–6, 7–9, 10–12 and 13–15 were electrically loaded using the same DC signal, but with the addition of an AC ripple component of magnitude: 10 Hz, 55 Hz, 254 Hz and 14.8 kHz respectively. As discussed in Section 3.1 the peak-to-peak magnitude of the current ripple was maintained constant at 1.2C.
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.
By comparing the EIS results presented in Fig. 8, Fig. 9, it can be seen that cells cycled with a current ripple at 14.8 kHz, experience a relatively rapid rise in R t (circa: 0.02 Ohms) between 0 and 600 cycles; the rate of rise of resistance (R t) for the same cells then reduces considerably between 600 and 1200 cycles.
Many early laboratory and real world studies of lead acid (Pb) batteries have shown that AC ripple may cause the cell to experience shallow discharge cycles, that in turn may lead to gassing , grid corrosion , , and internal heat generation , , , .
