A Megawatt-Level High-Voltage Charging Scheme for Pure Electric Heavy Trucks
With increasing global concerns for environmental conservation,port mining transportation is actively transitioning to mitigate its adverse environmental impacts.Pure electric heavy trucks,characterized by zero emissions and low operational costs,have emerged as an ideal sustainable solution.However,this transition also brings about new challenges,particularly in the construction and operation of charging infrastructure.This paper addresses this issue through an in-depth exploration and proposes an innovative megawatt-level high-voltage charging scheme directly powered by a 10 kV system,aimed at enhancing charging efficiency and operational effectiveness.By implementing this scheme,ports and mines can conveniently meet the charging demands of electric trucks,further advancing sustainability objectives.
