The invention relates to a battery energy processing device, a control method and a vehicle. The device comprises a conversion device of which the first confluence end is connected with the positive electrode of a battery and the second confluence end is connected with the negative electrode of the battery; the first end of the motor winding is connected with the midpoint of the conversion device; the first capacitor and the first switch are connected in series between the second end of the M-phase winding of the motor winding and the second confluence end of the conversion device; and the second switch is connected between the second end of the M-phase winding and the second end of the P-phase winding. The control method of the battery energy processing device comprises the steps that in a first preset state, the first switch is controlled to be switched on, the second switch is controlled to be switched off, the M-phase bridge arm corresponding to the M-phase winding is controlled so that external charging equipment can charge the battery, and meanwhile the P-phase bridge arm corresponding to the P-phase winding is controlled so that the battery and the P-phase winding can be charged and discharged so that heating of the battery can be achieved. Therefore, the utilization efficiency of the motor is improved, and the integration level of the whole vehicle is improved.
