Analysis of the Advantages and Disadvantages of Battery Swap Stations and High-power Fast Charging Piles for Electric Heavy Trucks Taking Guizhou Region as a Typical Case
This paper focuses on the application of battery swap stations and high-power fast charging piles in the application of electric heavy trucks in Guizhou.First,the background,objectives and methods of the study are described,including data collection,research and theoretical analysis.Then,the advantages and disadvantages of battery swap stations and high-power fast charging piles were analyzed,and the battery swap stations had advantages in terms of floor space,battery swap efficiency,and friendliness to the power grid and battery,but the early construction cost was high,the operation and management were complex,and the service scope was limited.High-power fast charging piles occupy a small area,mature technology,good compatibility,low construction cost,and wide range of application,but they have a great impact on the power grid,damage the battery,and the charging efficiency is affected by environmental and vehicle factors.Finally,according to different regions(thermal power and coal industry concentration areas,logistics industry concentration areas,mining enterprise areas),the layout of charging and swapping infrastructure is proposed.
