6 FAQs about [Residual energy storage]
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.
Why do prosumers use residual energy?
Both the increased grid purchase energy price and the decreased grid sold price have triggered significantly self-supplying. Therefore, prosumers have focused on utilizing residual energy (RE), which is excess energy for local demand, locally to increase self-supplying rather than transferring to the grid .
Can a SOE estimate residual energy?
Unlike the State of Charge, which solely reflects the charge, the SoE can feasibly estimate residual energy. The existing literature predominantly focuses on showcasing diverse methods with a gap in conducting in-depth analysis and comparison of the SoE.
How is residual energy determined in a battery cell?
Equation (4) demonstrates that the stored residual energy is directly related to the SoC of a battery cell, meaning that the SoEstored can be determined after the diffusion processes have completely decayed by measuring the terminal voltage presenting a significant opportunity in the field of residual energy estimation.
Does state of charge underestimate residual energy?
Compared to the State of stored Energy, we demonstrate that the State of Charge underestimates the residual energy by more than 3 %, highlighting the importance of adequate SoE estimation.
