Bidirectional Charging in V2G Systems: An In-Cell Variation Analysis of Vehicle Batteries

Vehicle-to-grid (V2G) technology enables bidirectional charging of electric vehicle (EV) and facilitates power grid ancillary services. However, battery pack in EV may develop in-cell dynamic variations over time. This is due to the structural complexity and electrochemical operations in the battery...
