Ripple voltage and the resulting ripple current imposed on a battery DC bus could have an adverse effect on the battery and electronic equipment connected to the battery. Consequently, this ripple should be taken into consideration when maintaining, testing, and monitoring a battery. Ripple is not to be confused with noise. Some history.
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.
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.
DC OUTPUT RIPPLE is a common and important specification for stationary battery chargers. The term “ripple” usually refers to the ac voltage measured at the battery terminals, but it may also be measured at the charger output terminals, if the battery is disconnected from the dc bus for maintenance.
