| description | The utility model relates to a charger, and provides a DC charging double-gun output power scheduling device and a charger in order to solve the problem of circulating current risk between batteries caused by faults during double-gun output of a conventional charger. An interlocking device of the dispatching device comprises a first single-pole double-throw output control relay, a second single-pole double-throw output control relay, N power dispatching control relays, a first intermediate relay and a second intermediate relay. The movable contacts of the single-pole double-throw relays are connected with the positive electrode of the low-voltage control power supply, the movable contacts are connected with the contacts of the corresponding intermediate relays and the electromagnetic coils of the first and second output direct current contactors after being connected with one another, and the first static contacts of the first and second output control relays are correspondingly connected with the electromagn |
