What does energy mean in a battery?
Energy or Nominal Energy (Wh (for a specific C-rate)) – The “energy capacity” of the battery, the total Watt-hours available when the battery is discharged at a certain discharge current (specified as a C-rate) from 100 percent state-of-charge to the cut-off voltage.
What is a watt hour in a battery?
An amp hour (Ah) is a measure of charge and provides an estimate of how much energy a battery can hold. It is the amount of energy charge in a battery that will allow one ampere of current to flow for one hour. A watt hour (Wh), on the other hand, is a measure of power and indicates the equivalent to one Watt of average power flow over an hour.
