The invention discloses a stator, a flat wire motor, a power assembly and a vehicle. The stator is characterized in that a plurality of stator slots are uniformly distributed on the inner wall of a stator core along the circumferential direction; each phase of winding comprises a plurality of parallel branches which are rotationally symmetrical in the circumferential direction, each parallel branch comprises a plurality of hairpin coils which are connected through connecting wires and have different pitches, N layers of hairpin coils are arranged in any stator slot, and the hairpin coil of each parallel branch traverses N slot layers in different stator slots; when N is equal to (2n + 1) * 2, the total number combination of groove layers occupied by each parallel branch in each stator groove is 2n, or 2n, 2n-1 and 2n-2; when N is equal to 2n * 2, the total number combination of groove layers occupied by each parallel branch in each stator groove is 2n, 2n-1, or 2n, 2n-1 and 2n-2; and when N is equal to 2n + 1, the total number combination of the slot layers occupied by each parallel branch in each stator slot is n, n-1, or n, n-1 and n-2. Through the above mode, the stator provided by the invention can avoid the generation of circulation, reduces the manufacturing cost, and improves the processing and manufacturing efficiency.
