Impact of current ripple on Li-ion battery ageing

The aim of this paper is to investigate the impact of the current ripple, originating from the dc-dc converter of e.g. a PHEV powertrain, on the ageing of Li-ion batteries. Most research concerning batteries focuses on very low (μHz) to low (Hz) frequencies and low current ripples to create very accurate battery models which can determine e.g. the State of …

battery charging

The power of this converter is 50 kW and the average current in the inductor (the same as that on the battery) is 125 A. By designing the converter for a 20% current ripple I will have iL_min = 112.5 A and iL_max = 137.5 A. The frequency switch is 25kH. I wonder

Specter Engineering — Inverter DC Link Capacitor Selection

It''s good to be conservative so select a capacitor with a ripple current rating that is 1.1x or higher than your worst case ripple current. With that said.. because this is a thermal rating, you could rate it based on the time average phase current based on your load cycle.. if you are really trying to optimize for power density.

OverviewVoltage rippleFiltering in power suppliesCapacitor vs choke input filtersRipple currentFrequency-domain rippleSee also

Ripple (specifically ripple voltage) in electronics is the residual periodic variation of the DC voltage within a power supply which has been derived from an alternating current (AC) source. This ripple is due to incomplete suppression of the alternating waveform after rectification. Ripple voltage originates as the output of a rectifier or from generation and commutation of DC power. Ripple (specifically ripple current or surge current) may also refer to the pulsed current consump…
