electricity charge for charging 2v 3000Ah batteries

[Nhoy]

hi, can you tell me how to calculate KWH charge for charging a 2v 3000ah

batteries (24 units in series), the batteries are fully drawn and need

to be fully charge.

(the charging would be tap to 3 phase, current voltage is 230V, partial charging in 12 hours starting at 52 amp and end at 18amp.)

You can think about it like this

the coltage is 2 v

3000Ah means that if the current is 3000A the battery will provide electrical energy for 1 hour

so simply the formula is like this : E= 2 x 3000 = 6000 WH = 6 KWH energy required

 

P.S : this calculations are for IDEAL enviroment, but could be applied 99% of times,
