6 FAQs about [Lithium battery power ripple]

How does ripple current affect battery life?

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.

How does ripple affect accelerated ageing of lithium bat-Teries?

The trend to reduced filter capacitors and even dynamically reconfigurable batteries further increases the ripple. The influence of rippled load on lithium bat-teries is therefore receiving increased attention. According to recent studies, accelerated ageing strongly depends on the frequency of the ripple.

What causes a ripple in a battery?

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).

Does current ripple affect battery performance degradation?

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.

What is the magnitude of a current ripple in a cell?
