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

Thank you Professor. this is such a great lecture.

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?

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

[satyam]

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

Greogery Plett lecture is superb, this lecture is useless
