A multiple switch capacitor technics uses a principle of averaging different values. And there is one big disadvantage of all switching capacitors architectures: the smaller is s voltage difference the slower power transfer is. You can charge a battery in 3 hours, and then balance it during 16 hours. But Chinese manufacturers like it cause capacitors and mosfets are cheap, and they still can call it “an active balancer” All but a dynamic charging active balancing methods do not manage an energy transfer current. It can be any depending on esr, conductance, internal resistance, etc. I think it’s not good for a battery. A charging of a capacitor fast causes an energy loss as a radiation due to Maxwell equation besides of all A multiple transformer technic is similar to a multiple capacitor one: due to an averaging, higher charged cells fill a capacitor/inductor, and lower charged cells consume this energy. All at once. Everything happens automatically. No sophisticated controller is needed. You do not understand how this method works. The lossless charging is better to implement with two chargers. This eliminates all switches between cells (each mosfet adds 2-10 mOhm to an internal resistance)
Very poor use of the English language. If all the ahhs , and yeahs were eliminated from the words strung together this could easily be an informative five minute video ! The intro part of the video may have stroked the ego of the main presenter however it served no useful function to help enlighten the audience. I wouldn't trust anything designed by these guys.
Thank you so much Sir for sharing your knowledge through which many of my doubts are clarified. It has been a wonderful session
You are most welcome! Happy Learning
Amazingg videos.. great explanation
Wonderful...thank you sir
Very nice and in details. Thanks
Glad you liked it!
good😍😍
what is the value of capacitor that can be used for cell balancing using switched capacitor topology?
Any. A switching frequency will depend on this value (limited with MOSFET specs of course). Do start from 10-22uF. ESR is more important
26:30 "controller closes the mosfet so that cell is shuted and it drains energy via the register." Many wrong explanation in this video
