Calculate your charging time yourself
First, calculate your charging power (P) by multiplying the voltage (U, in volts) by the current (I, in amps). This gives you a value in watts.
P = U x I
Example: 16 A x 230 V = 3680 W
Divide the load power by 1000 to get a value in kilowatts.
Example: 3680 W = 3.7 kW
Divide the capacity of your battery (expressed in kWh) by the figure to obtain the charging time.
Example: 24 kWh / 3.7 kW = 6.5 hours
