6 FAQs about [Calculation of residual value of energy storage system]
What is residual energy in energy storage?
For energy storage systems, the residual energy of the battery is the cumulative energy charged or discharged from the current moment until the battery reaches the charge/discharge cut-off voltage when the energy storage battery is charged or discharged at a certain operating condition.
How is residual energy calculated in a battery pack?
From both theoretical and practical aspects, the cells with average voltage in the battery pack are selected as representative cells and their residual energy is estimated as the residual energy of the battery pack at the current moment.
How do you determine the residual value of a battery?
Battery appearance [7, 8], charge/discharge curves [, , ], open-circuit voltage [10, 11], capacity , and internal resistance [13, 14] are all typical methods for determining the residual value and categorizing batteries.
