The disclosure relates to the technical field of battery charging and swapping, and in particular, to a power control method and system for a battery charging and swap station, a medium, an apparatus, and the battery charging and swap station. The disclosure is intended to solve the problem of how to implement integrated power management of the battery charging and swap station. To this end, the power control method in the disclosure includes: obtaining a power limit of the battery charging and swap station, a station-side total requested power of a battery swap station, and a pile-side total requested power of a number of charging piles; calculating a sum of the station-side total requested power and the pile-side total requested power; comparing the power limit with the sum of the two powers; when the power limit is less than the sum of the two powers, determining, based on a preset allocation strategy, a station-side actual allocated power for the battery swap station and a pile-side actual allocated power for the number of charging piles; and respectively performing, based on the station-side actual allocated power and the pile-side actual allocated power, power allocation on one or more battery compartments and the number of charging piles. The disclosure can implement flexible and efficient power allocation between the battery swap station and the charging piles in the battery charging and swap station.
