Question

Give 5 reasons why usable capacity is smaller than nominal capacity.

Answer 1

➢ The nominal capacity is the volume of the tank when it is filled to the brim whereas, the usable capacity is the volume contained within the tank up to the maximum working level

➢ .Usable capacity of the battery is low because of the depth of discharge.

➢ The depth of discharge of usable capacity is up to 35% whereas the depth of discharge is more i.e, 50% more than the usable capacity.

➢ The nominal capacity of a battery is 10kwh and the usable capacity is 7kwh
