The invention relates to the technical field of hybrid electric vehicles, in particular to a power assembly of a hybrid electric vehicle and the hybrid electric vehicle. The power assembly of the hybrid electric vehicle comprises a power output mechanism and a speed change mechanism. The speed change mechanism comprises a speed change mechanism input shaft, a speed change mechanism output shaft, a third planet row, a fourth planet row, a B1 brake, a B2 brake and a C1 clutch. A gear ring of the third planet row is connected with a planet carrier of the fourth planet row, a sun gear of the third planet row is connected with a gearbox shell through the B1 brake, and a planet carrier of the third planet row is connected with a gear ring of the fourth planet row. A planet carrier of the third planet row and a gear ring of the fourth planet row are connected with the gearbox shell through the B2 brake. According to the power assembly, when the speed change mechanism is located at the third forward gear, the transmission efficiency of the whole speed change mechanism is close to 100%, and the energy loss of the speed change mechanism during power transmission can be remarkably reduced.
