An efficient hybrid algorithm based on particle swarm optimisation and teaching‐learning‐based optimisation for parameter estimation of photovoltaic models

IET Smart Grid, Volume 7, Issue 6, Page 1000-1018, December 2024.
In order to estimate the unknown parameters of the PV models more precisely and reliably, an efficient hybrid algorithm based on particle swarm optimisation and teaching‐learning‐based optimisation (PSOTLBO) is proposed in this paper. The comparative results between PSOTLBO and other 12 advanced algorithms demonstrate that PSOTLBO has outstanding ...

State‐of‐health estimation of lithium‐ion batteries: A comprehensive literature review from cell to pack levels

Energy Conversion and Economics, Volume 5, Issue 4, Page 224-242, August 2024.
Abstract Lithium‐ion battery state‐of‐health (SOH) monitoring is essential for maintaining the safety and reliability of electric vehicles and efficiency of energy storage systems. When the SOH of lithium‐ion batteries reaches the end‐of‐life threshold, replacement and maintenance are required to avoid fire and explosion hazards.
