Hi, I have no engineering background whatsoever.
I'm trying to estimate the recharge cost of a battery, say lead acid.
So if the battery characteristic is as follows:
capacity is 15000 Wh.
Charge efficiency is 80%
Charge current is 15% of capacity, ie. 2,250 Wh
Electricity cost is 1 USD/kWh (on grid)
If the battery is discharged for 5000 W for 1 hour,
then I need 6000 W to fully recharge?
And it would cost me USD 6 to recharge? Is that right?
What is the charge current for in this case then?
Thx
