The invention provides a direct current converter, a direct current charging pile and an energy storage system. The DC converter comprises a first end; a second end; the first half-bridge circuit is connected with the first end, and the first half-bridge circuit comprises a first switching tube and a second switching tube which are connected end to end; the first switch is connected with the first switching tube in parallel; the second half-bridge circuit is connected with the second end, and the second half-bridge circuit comprises a third switching tube and a fourth switching tube which are connected end to end; the source electrode of the fourth switch tube is connected with the source electrode of the second switch tube; the second switch is connected with the third switch tube in parallel; and the first inductor is connected to a midpoint between the first switching tube and the second switching tube and a midpoint between the third switching tube and the fourth switching tube. The DC converter provided by the invention reduces the energy loss and improves the working efficiency.
