In large-scale energy storage devices such as batteries in electric vehicles (EVs) or household energy storage systems, the cost of energy consumed to charge the battery is a significant factor and is directly translated into the cost of the energy supplied by the storage device.
The battery energy storage system achieves a round-trip efficiency of 91.1% at 180kW (1C) for a full charge / discharge cycle. Grid-connected energy storage is necessary to stabilise power networks by decoupling generation and demand [1], and also reduces generator output variation, ensuring optimal efficiency [2].
Lithium-ion batteries (LIBs) have nowadays become outstanding rechargeable energy storage devices with rapidly expanding fields of applications due to convenient features like high energy density, high power density, long life cycle and not having memory effect.
Energy storage is important because it can be utilized to support the grid''s efforts to include additional renewable energy sources [].Additionally, energy storage can improve the efficiency of generation facilities and decrease the need for less efficient generating units that would otherwise only run during peak hours.
In the past few decades, electricity production depended on fossil fuels due to their reliability and efficiency [1].Fossil fuels have many effects on the environment and directly affect the economy as their prices increase continuously due to their consumption which is assumed to double in 2050 and three times by 2100 [6] g. 1 shows the current global
