Lecture 25 - SoH and SoC estimation and Self Discharge - Part 1

[@hblvsez]

Sir very nice explanation, we have expected from you lot of lectures to be improve the knowledge on EV charger technology, thanku somuch sir.....

Please, the second graph is not clear. the graph should be down from left to right.

[@sagaradoshi]

At 10minutes of video. Graph of SOC vs Voltage for charging at different C rates how the voltage for 0.5C greater than 0.2C i.e., how voltage for 2.5C>1C>0.5C>0.2C Ex at 50%SOC? Sir mentioned that V = OCV - Current*Resistance . If my current at 1.5C>1C>0.5C>0.2C then negative term (Current*resistance) is high so my Voltage should actually reduce right?

[@abo3mmar87]

The current is zero since it's an open circuit, (see the 3rd minute). This is not the charging current btw. Try to draw the circuit and integrate the external charging source, I hope you will reach a better understanding.

In the discharge curve, the cell is discharging with 2.3C but before that the cell charge with which C rate?? Can you please clear this

[@ElectricalwalaBorkarGuRu]

Great explaination sir...learn a lot about soc and soh...@Electrical wala Borkar GuRu

[@MAMTAMAHARJAN]

Thank you Professor. this is such a great lecture.

Kya naam hai Guruji Ka. 🙏🏼 Pranaam .

Please keep to the point more mathematical and simulation way,we are engineers not art students ,keep it fast to the point.

[@NN-uf5xt]

This is really rude of you. Please pay respect to professor. Equations you can learn by reading numerous books but what professor is giving is essence of how things are working, and sometime that is not clear from equations

Dude? You don't always get what u seek! It doesn't mean the other side is wrong!!

Greogery Plett lecture is superb , this lecture is useless
