【Abstract】In order to meet the needs of charging safety，service experience of high-power DC charging piles and improve their powerutilization，thispaper proposes aflexible poweralocationcontrol strategy.Basedonthetopologyof circular poweralocation，thepower alocationcontroltimingadalgorithmforcharging start，charging inprogessandrelease attheendaredesigned.Theutilizationrateof power nodes is improvedbystaticand dynamicpollingswitching.To ensure stableoperationofthesystem，thedefinitionofminimumremainingrequiredpowerisintroduced，andthediferencein remainingrequiredpower，thenumberofswitching times inasingleinsertiongun，andthefiltering timearecomprehensively judgedtoavoid frequentswitching.Verificationresult shows thatthisstrategycanimproveaverage powerutilizationrate from （204號(hào) 1.76% to 2.24% ，demonstrating significant optimization effect.
