Technical FAQs 4

What is a ripple current in a battery?

Ripple currents are Alternating Current (AC) components, i.e. high frequency oscillations, superimposed on a Direct Current (DC) flow within a battery system. These ripples are typically generated by power electronics, including inverters, DC-DC converters, and rectifiers.

How to simulate AC current ripple during charging and discharging a battery?

The GEIS technique can be used to mimic an AC current ripple during charging and/or discharging of a battery. Figure 2: How to simulate AC current ripple measurements using the GEIS technique. Choose the desired amplitude “Ia” (peak type amplitude). Add a limit by clicking on the “+” button. Select “Time” then enter the desired experiment duration.

What causes a battery to ripple?

Ripple is the AC component of a system’s charging voltage imposed on the DC bus. It can also be reflected from load equipment. It could be caused by poor charger design, poor inverter design, failing capacitors, or by the interaction of load equipment connected to the DC bus. The result is a ripple current flowing into the battery.

Does current ripple affect battery capacity loss?

The comparative results indicated that current ripple signals such 3 Amps and 6 Amps peak to peak amplitude cause notable capacity loss when compared with pure quality DC current signal. The effect of AC current ripple signals on the degradation of lithium batteries has been correlated with an Internal Impedance growth under such duty cycle.
