4 Ideally how much energy could a 24 V 200 amphour battery s

4. Ideally, how much energy could a 24 V, 200 amp-hour battery store? Assume that the battery does not change voltage with discharge. Provide answer in units of Joules.

Solution

Battery energy = Volts_average x Amp hours capacity

Therefore energy E= 24vX 200 amp hour

E=4800watt hour

i watt hour=1 W x 3600 s = 3600 Joule

so E=4800 X3600 J=17280kJ
