A. 12.8 hours
B. 13.0 hours
C. 14.0 hours
D. 12.7 hours
Ans: D. 12.7 hours
Explanation:
Here given that
battery Ah ratting = 200Ah
charging current of battery should be 10 % of Ah ratting
so Charging current=200 * 10/100
= 200 * 0.1
= 20 A
Due to Some losses we take more Amp 20-22A
If we Take 22A for charging purpose of battery
Formula for charging time T = battery Ah / battery charging Amp
Here is given that
battery Ah= 200Ah and battery charging Amp =22A
Charging Time T = 200 / 22 =9.09 hrs
this is only for ideal case
But in actual case 40 % or more losses occurred in battery charging
so battery Ah = 200 * 40 % losses during charging time
= 200 * 40 / 100
= 80 Ah
so 80Ah increased due to losses
so now total Ah = 200Ah + 80 Ah
= 280 Ah
Now battery Charging time = battery Ah / Charging current
= 280 / 22
= 12.7 hours
So time required for battery charging is 12.7 hours
Good to Know :
- Battery store potential energy in form of potential energy when required it converted into electrical DC power.
- Battery Have two terminal one is positive terminal and other is negative terminal. Positive terminal known as cathode terminal and negative terminal known as Anode terminal.
- There are Active and passive component in our system and battery is active component.
- Service life of battery is 5-10 years only.
- Battery cell polarity charged during charging and discharging cycle.
