1. A power control method for a battery charging and swap station, wherein the battery charging and swap station comprises a battery swap station and a number of charging piles, the battery swap station is provided with one or more battery compartments, the battery compartment is configured to charge a traction battery, the charging pile comprises a charging gun, and the charging gun is capable of being in plug-in connection with a charging socket provided on a new energy vehicle, so as to charge the new energy vehicle; and
the power control method comprises:
obtaining a power limit of the battery charging and swap station, a station-side total requested power of the battery swap station, and a pile-side total requested power of the 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 the one or more battery compartments and the number of charging piles;
wherein the step of “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” further comprises:
determining a station-side pre-allocated power for the battery swap station and a pile-side pre-allocated power for the number of charging piles;
comparing the station-side pre-allocated power with the station-side total requested power and comparing the pile-side pre-allocated power with the pile-side total requested power; and
determining, based on a comparison result, the station-side actual allocated power and the pile-side actual allocated power.
