1. A method, comprising:
determining, by the charging station, whether a charging device is connected via the charging station to a first phase of a three-phase power source;
transmitting, by the charging station, a first control signal to adjust a charging rate of the charging device to consume the current from the first phase;
detecting that the charging device is connected to a second phase of the three-phase power source, wherein the second phase is distinct from the first phase; and
upon determining that the charging station offers less than a default charging rate to the charging device, transmitting a second control signal to adjust the charging rate of the charging device to consume the current from the second phase of the three-phase power source.
