1. A battery heating control method, comprising:
collecting a battery parameter of a battery module;
in response to the battery parameter of the battery module meeting a preset heating condition, controlling a traction battery and a feed battery of the battery module to charge and discharge each other so that the battery module is heated through mutual charge and discharge of the traction battery and the feed battery; and
controlling the traction battery of the battery module to power a motor of a vehicle,
wherein controlling the traction battery and the feed battery of the battery module to charge and discharge each other comprises:
obtaining a motor feed current and an initial discharge effective value of the feed battery;
calculating a discharge adjustment value for the feed battery based on the motor feed current and the initial discharge effective value of the feed battery; and
during discharging of the feed battery, adjusting a discharge current of the feed battery based on the discharge adjustment value.
