Battery energy is the electric energy stored in a battery cell or battery pack. It shows the capacity of the battery to provide electric energy for a prolonged period of time. The higher the battery energy the longer the time it can supply electric energy. A typical battery stores chemical energy and converts it to electric energy when it''s connected to an electrical load (consumer).
The calculation of the SoH with the energy-based method is therefore an understandable method, but neither an easy to perform, nor a reliable one, although it is not dependent on the whole vehicle degradation as the range-based method. Recreating testing environments to measure energy for both new and used batteries is nearly impossible.
The amp-hour is a unit of battery energy capacity, equal to the amount of continuous current multiplied by the discharge time, that a battery can supply before exhausting its internal store of chemical energy.; An amp-hour battery rating is only an approximation of the battery''s charge capacity, and should be trusted only at the current level or time specified by
