Besides its effect on the life time of the battery cells, the ripple current has potential benefits for the state of health diagnosis of the battery. The voltage response of the battery cells to the high frequent stimulations of the ripple current contains information of the cell’s impedance spectrum, which changes with the aging process.
The ripple is generated by the semiconductor switching when converting the DC voltage of the battery to AC with variable frequency and amplitude for the motors or to DC with a different voltage level (e.g., 400 V to 12 V).
This paper documents an experimental investigation that studies the long-term impact of current ripple on battery performance degradation. A novel test environment has been designed to thermally manage the cells to 25 °C while simultaneously exciting the cells with a coupled DC and AC load profile that is representative of real-world vehicle use.
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.
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 , , , .
Figure 8. The test setup of the ripple tests consists of a computer that controls the battery tester, which cycles the battery cells, an impedance measurement device for checkups, and an external measurement system, which measures current and voltage with high sampling rates.

Increasing the capacitance in the converter can reduce the ripple in the current, the high frequency heating of the battery is reduced and improving the charging and discharging efficiency of the battery. However, the capacitance cannot be increased indefinitely, which leads to a larger size of the converter. This plays an important role in ...

My understanding is voltage ripple is largely caused by current ripple and is due to the internal resistance of the battery. The reason I am asking is our preferred topology may generate a large charging current ripple at twice the mains frequency 120 Hz ( due to PFC output voltage ripple ), and we will be able to make better design trade-offs if we know how big the current ripple can be.
