Abstract:

Electric vehicle charging technology has been developed in the long run with the increasing popularity of electric vehicles.The on-board energy storage system is attracting the attentions due to the plug-and-play nature,which do not require the support of the charging piles.Among these, the on-board energy storage converter based on the driving multiplex motor and the driving converter has been widely studied in recent years due to the high system integration and power density.The researches on the topologies of the driving multiplex on-board energy storage systems are induced,and the advantages and disadvantages of each topology are summarized.The analysis method of torque and ripple is put forward,which is key indicators for driving multiplex on-board energy storage system during charging.The various topology schemes are compared based on these relevant indicators.

Key words: electric vehicles, on-board energy storage systems, driving multiplex, asymmetric current torque, normalized ripple coefficient
