how many kilowatt-hours of electricity can the energy storage device store at most
How much energy can be stored in a battery?
For now. Power = rate of doing work Watts or kiloWatts (1000 Watts = 1 kW.) Energy or work done is measured in Joules. 1000 Joules = 1 kiloJoule = 1 kJ. In one hour at one Watt we use 1 W x 3600 s = 3600 Joule = 3.6 kJ. Battery energy = Volts_average x Amp hours capacity = Watt hour capacity.
