1. A server, comprising:
a transceiver configured to communicate with a charger; and
a processor configured to:
determine, based on state information of a vehicle, a required state of charge (SoC);
control, based on charging and discharging from an SoC of the vehicle to the required SoC and based on electricity charging costs over periods stored in an electricity rate table, the charger to increase an expected profit, wherein based on a 24-hour period, electricity rates are predicted for each time slot and stored in the electricity rate table;
based on controlling the charger, adjust the electricity charging costs over the periods so that a first electricity charging cost at a start time of a first period of the periods is lower than a constant electricity charging cost over the first period, and the first electricity charging cost is increased over the first period;
linearly transform the electricity charging costs over the periods stored in the electricity rate table by adjusting the first electricity charging cost at the start time downward and adjusting an electricity charging cost at an end time of the first period upward, wherein the constant electricity charging cost over the first period is different from a second constant electricity charging cost over a second period of the periods;
set the adjusted electricity charging costs to temporarily override the constant electricity charging cost over the first period and cause, based on the adjusted electricity charging costs, the charger to automatically adjust a sequence of charging and discharging of the vehicle associated with the first period;
adjust the linear transformation so that a result of the linear transformation does not overlap with electricity rates of adjacent time periods, and control the charger to maximize the expected profit based on a transformed electricity rate within a same rate time period, wherein the linear transformation comprises a transformation in which a transformed electricity rate is lower when closer to a start time within the same rate time period, and higher when closer to an end time within the same rate time period; and
generate and transmit, via the transceiver, a control signal to the charger to execute the charging or discharging based on the transformed electricity charging costs, such that the transformation results are reflected in real-time charger operation of the charger.
