The invention discloses a stator, a flat wire motor, a power assembly and a vehicle. The stator is characterized in that the inner wall of a stator core is provided with s stator slots; the stator winding comprises a three-phase winding, each phase winding comprises p parallel branches, and each parallel branch comprises a plurality of hairpin coils which are connected through connecting wires; wherein the plurality of card issuing coils comprise long-distance card issuing coils with the pitch being s/(2p) + a, whole-distance card issuing coils with the pitch being s/(2p) and short-distance card issuing coils with the pitch being s/(2p) + a-4, and a is an integer larger than or equal to 2 and smaller than or equal to 4; in each parallel branch, the first supporting leg and the second supporting leg of the short-distance hairpin coil are located on the kth slot layer and the (k + 1) th slot layer respectively, the first supporting leg and the second supporting leg of the long-distance hairpin coil are located on the (k + 1) th slot layer and the (k + 2) th slot layer respectively, and the first supporting leg and the second supporting leg of the whole-distance hairpin coil are distributed on the first slot layer or the nth slot layer. According to the stator provided by the invention, the manufacturing cost of the stator can be reduced.
