The invention discloses a power distribution device, a power distribution system and a commercial vehicle, and relates to the technical field of automobile power distribution, the power distribution device comprises a plurality of power distribution boxes, the plurality of power distribution boxes are correspondingly arranged in a plurality of power distribution areas of a whole vehicle, each power distribution box comprises a power distribution control panel, a positive wire, a negative wire, a plurality of relays and a CAN bus, one end of the positive wire is connected with a positive connector on the power distribution control board, the other end of the positive wire is connected with a storage battery positive electrode of the whole vehicle, one end of the negative wire is connected with a negative connector on the power distribution control board, and the other end of the negative wire is connected with a storage battery negative electrode of the whole vehicle. One end of each relay is connected with a positive electrode connector on the power distribution board, the other end of each relay is connected with a power distribution interface on the power distribution control board, and the CAN bus is used for transmitting a power transmission and distribution instruction to the power distribution control board so as to control the relays to be conducted. On-line loss is reduced, wire harness resources are saved, the weight of the whole vehicle is reduced, and the problem that an original power distribution interface is solidified and cannot be changed is solved.
