The invention discloses a split type direct current charging pile multiple annular power distribution device which comprises a plurality of annular power pool sets, the annular power pool sets are connected in parallel, each annular power pool set is composed of a plurality of power pools, and the power pools in the same annular power pool set are connected in series to form a loop. A switch is connected in series between two adjacent power pools in the same annular power pool group to control the on-off of a loop, the power pools in the plurality of annular power pool groups correspond to each other, and the corresponding power pools in different annular power pool groups are connected in parallel. The method is suitable for the charging pile, the multiple annular power distribution design is adopted, the annular power pools are connected with one another, power sharing among the annular power pool sets is achieved, infinite capacity expansion and gun expansion can be achieved according to actual requirements, and the problem that capacity expansion or gun expansion cannot be achieved in a power dispatching scheme at the present stage is thoroughly solved.
