Multi-timescale Power and Energy Assessment for Lithium-ion Battery and Supercapacitor Hybrid Energy Storage System

The lithium-ion battery (LIBs) has become one of the optimal choices for energy storage systems (ESS) in many fields, such as electric vehicles (EVs) and microgrids. However, an ESS which only depends on batteries has several drawbacks: (1) In order to meet the peak power demand, the power density of the batteries needs to be
