calculate the first electric power based on the maximum charge capacity of the battery that is smaller than the determined sum;

notify the electric power system of the calculated first electric power; and

control a second electric power supplied to the electric power system based on the calculated first electric power.

2. The information processing device according to claim 1, wherein

the CPU is further configured to calculate the first electric power based on summation of the corresponding electric power to be supplied by each of the plurality of vehicles that is unreserved during the supply period.

3. The information processing device according to claim 1, wherein

the CPU is further configured to calculate the corresponding electric power to be supplied by each of the plurality of vehicles such that, between a time duration from the end time of the supply period to the start time of the reservation of the first vehicle, the battery is charged by an amount of charge required by the first vehicle based on the reservation information.

4. The information processing device according to claim 1, wherein

based on a determination that the sum of the product of the time duration from the current time to the start time of the supply period and the first amount of electric power, and the second amount of electric power is less than the maximum charge capacity of the battery,

the CPU is further configured to calculate the first electric power based on the product of the time duration from the current time to the start time of the supply period and the first amount of electric power, and the second amount of electric power.

5. An information processing method, comprising:

acquiring power supply request information that includes information on a supply period during which an electric power system is requesting supply of electric power and reservation information of a first vehicle, wherein the power supply request information is acquired from the electric power system;
