As these batteries reach the end of their life cycle, efficiently utilizing their residual value has become a key issue that needs to be resolved. This paper reviews the key issues in the cascade utilization
Accurate residual value assessment of retired power battery packs is vital for second-life applications. Traditional metrics such as state of health (SOH) tend to underestimate pack value due to their
With the large-scale retirement of power lithium-ion batteries in electric vehicles, the appropriate disposal of retired batteries (RBs) has become an important concern. Evaluating the residual value and
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
Accurately calculating the capacity of battery packs is of great significance to battery fault diagnosis, health evaluation, residual value assessment, and predictive maintenance in electric vehicles (EVs).
To overcome the particle degeneracy and maintain the precision of particle filtering, a mapping particle filter (MPF) method is applied to predict the residual life of lithium-ion battery.
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
Therefore, this paper proposes a method for estimating the residual energy of battery packs in energy storage based on the prediction of operating conditions and the representative cell.
The residual life prediction of lithium-ion battery can remind the user to replace the battery in time to ensure an efficient operation for the power system, but the inaccurate life prediction may cause the waste of resources
