The correct specification charger is critical for optimal performance and safety when charging Li-Ion battery packs. Your charger should match the voltage output and current rating of your specific battery type. Lithium batteries are sensitive to overcharging and
It is crucial to know if certain frequencies accelerate battery degradation and should be avoided. This applies in particular for EV batteries with an expected …
Sinusoidal ripple-current charging has previously been reported to increase both charging efficiency and energy efficiency and decrease charging time when used to charge lithium-ion battery cells. In this paper, we show that no such effect exists in lithium-ion battery cells, based on an experimental study of large-size prismatic cells. Additionally, we use a …
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 …

It is known that, while charge current oscillations which reverse the current lower than 0.05 X C20 are unlikely to greatly affect the battery [1,2], (in a 300A/h battery this would be: 300/20 = 15, 15 X 0.05 = 0.75A), current reversal above this figure is likely to

The lithium-ion (Li-ion) battery in electric vehicles charged by photovoltaic (PV) is a feasible solution for reducing grid demand. The existing standalone PV system with pulse-ripple-current (PRC) charging uses one converter and battery; and the PV remains idle in the PRC rest period, making the system inefficient. In this paper, one more …
I am designing a bidirectional DC-DC converter to charge and discharge batteries on a DC bus. 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 ...
