Dec 8, 2019 · I went through an application note from Texas Instruments referenced as snva829 ( the link http://www.ti.com/lit/an/snva829/snva829.pdf page 2 and 3) where they have discussed superficially the traditional CC/CV circuit.

I have a few weeks with a problem in the design of my bench power supply. First of all I have this design from this guy on YouTube https://youtu.be/_CFIovMkRyg that ...

I want to design a CC/CV (constant current/constant voltage) circuit in which I can set the voltage limit or current limit with DAC's 0 to 5V range. I know how to design variable CC circuits and CV:

Dec 25, 2019 · What is the voltage graph from the point of view of the charger while performing a CC/CV charging? Isn't a "Dedicated Lithium Ion CC/CV charger" simply "a Constant Voltage DC Source with Current Limit" (like we use in labs)? Looking closely to the CC/CV transition of the graph, there is a sharp turn in the battery current¹.

Aug 19, 2021 · So, which method is more correct and general such that I can apply it on all such problems? Please let me know if the second method is correct approach or not. Also what do they mean by this?- A power supply will operate in constant voltage (CV) mode provided the load does not require more current than the current limit setting. Link for the image source for reference- …

I'm implementing a CC-CV algorithm for charging a li-ion battery. I'm confused what is the maximum allowed charging voltage during CC (constant current) phase. All application notes and datasheets, I've found state that charging in the CC mode …

As many others before, I'm aiming to build my own simple CC CV lab bench PSU based on the LM317 regulator. Now, I've defined most of the circuitry, but I'm stuck with a particular design choice reg...

Mar 17, 2021 · One would require a lot more feedback control and precision (adjusting a CC source to produce a constant voltage). While the other would require a lot less control (just using a transistor to change the CC to a CV). Plus, as you said, you'd need to "stop" charging at some point, so a transistor to break the charging circuit would already be there, bonus.

Jul 9, 2020 · For some background, most if not all modern charging solutions for lithium ion batteries use a CCCV model for charging: As the diagram explains, we charge at a constant current, and then "sud...

Jul 8, 2024 · I want to build a universal charger for Li-Ion, LiFePo4, VRLA-AGM, and similar batteries (or just a power supply with CC/CV). I'll designate in advance that the maximum output voltage of the converter is 3-35 V, and the current is 40 A (the converter is only step-down, the maximum voltage is limited to either 35 V or VIN — losses on components).
