This invention discloses a control method and system for the working mode of batteries in a battery swapping station. The battery swapping station includes an in-station monitoring platform and several sets of corresponding chargers and charging compartments. Each charger in each set is communicatively connected to the battery pack installed in the charging compartment. The in-station monitoring platform is also communicatively connected to each charger. The control method includes the following steps: the in-station monitoring platform sends a power-on command to the corresponding charger; upon receiving the power-on command, the charger controls the battery pack in the corresponding charging compartment to be powered on at low voltage; the in-station monitoring platform responds to the charging start command by sending a first message to the charger; upon receiving the first message, the charger forwards the first message to the battery pack in the corresponding charging compartment; and upon receiving the first message, the battery pack enters the battery swapping station charging mode. This invention simplifies the structural design of the battery swapping station, reduces costs, and ensures good DC charging of the batteries within the station.
