Research and Design of Group Control Low-Power DC Charging System
[Purposes]With the rapid development of the electric vehicle industry,the charging demand of electric vehicles is also increasing.Residents urgently need a charging method with lower cost,stron-ger applicability and faster speed.In order to solve the problems of low utilization rate,slow charging speed and high construction cost of current charger equipment,a new group control low-power DC charg-ing system is designed.[Methods]By comparing and analyzing the advantages and disadvantages of ex-isting products,the functions and advantages of group control low-power chargers are pointed out,and the technical difficulties and key points of the product are summarized.[Findings]The group control low-power charging technology combines the advantages of traditional DC piles and AC piles,and has the characteristics of fast charging,high equipment utilization,strong environmental adaptability and low cost.[Conclusions]Currently,there are still issues with the formulation of power allocation strategies and the design of heat dissipation structures for low-power DC chargers.With the continuous develop-ment of research and development technology and the tackling of key issues,group control low-power DC charging systems will rapidly rise and occupy an important position in the market in the near future.
