The disclosure relates to the technical field of electric vehicles, and in particular, to a control method and apparatus for a traction battery, a vehicle, a medium, and a device, aiming at solving the problem of how to conveniently and efficiently heat a traction battery, especially a large-capacity traction battery. To this end, the control method for a traction battery according to an embodiment of the disclosure comprises analyzing whether each traction battery needs to be heated on the basis of temperature information of the traction battery, and controlling a bidirectional DC converter and the traction battery which needs to be heated to form a charging and discharging circuit to cyclically charge and discharge the traction battery, so as to achieve the goal of heating the traction battery. By means of the foregoing steps, the characteristic of high internal resistance of a lithium-ion traction battery at a low temperature can be used to make the traction battery generate heat by means of a cyclic charging and discharging process, to achieve the heating of the traction battery, that is, the performance of the traction battery can be improved, the time for charging the traction battery is reduced, and the safety of the traction battery is further improved.
