Abstract

A method performed by an information processing apparatus, the method includes, for each of a plurality of vehicles for which charging in a target time period has been applied for, acquiring vehicle information including predicted remaining SOC to be remaining at a start of the target time period and/or predicted consumed SOC to be consumed in a vehicle use period after an end of the target time period, determining, based on the vehicle information, whether each of the plurality of vehicles is a target for charging in the target time period, and determining a charging plan to charge a vehicle being determined to be eligible for charging, among the plurality of vehicles, in the target time period.

First claim

The invention claimed is:

1. A method performed by an information processing apparatus, the method comprising:
for each of a plurality of vehicles for which charging in a target time period has been applied for, acquiring vehicle information including predicted remaining SOC (state of charge) to be remaining at a start of the target time period and/or predicted consumed SOC to be consumed in a vehicle use period after an end of the target time period;
determining, based on the vehicle information, whether each of the plurality of vehicles is eligible for charging in the target time period;
determining a charging plan to charge a vehicle being determined to be eligible for charging, among the plurality of vehicles, in the target time period; and
acquiring supply power information including supply electrical energy to be supplied by a power supply facility for charging vehicles in the target time period,
wherein the information processing apparatus is configured to:
determine whether charging electrical energy required to bring the predicted remaining SOC of all the plurality of vehicles to a predetermined charged state is less than or equal to the supply electrical energy; and
determine all the plurality of vehicles to be eligible for charging when it is determined that the charging electrical energy is less than or equal to the supply electrical energy, and

wherein the supply electrical energy is a sum of commercial supply electrical energy to be supplied by a commercial power source, predicted electrical energy predicted to be supplied by a renewable energy source, and storage battery supply electrical energy to be supplied by a storage battery, each of which is multiplied by a coefficient.

2. A method, performed by an information processing apparatus, the method comprising:
for each of a plurality of vehicles for which charging in a target time period has been applied for, acquiring vehicle information including predicted remaining SOC (state of charge) to be remaining at a start of the target time period and/or predicted consumed SOC to be consumed in a vehicle use period after an end of the target time period;
determining, based on the vehicle information, whether each of the plurality of vehicles is eligible for charging in the target time period; and
determining a charging plan to charge a vehicle being determined to be eligible for charging, among the plurality of vehicles, in the target time period,
wherein the information processing apparatus is configured to:
determine a vehicle whose predicted consumed SOC is greater than or equal to a first threshold, among the plurality of vehicles, as a first candidate for charging;
determine a vehicle whose value subtracting the predicted consumed SOC from the predicted remaining SOC is less than a second threshold, among the first candidate, as a second candidate for charging, when a predetermined condition based on at least the predicted remaining SOC of the vehicle as the first candidate is satisfied; and
determine a vehicle whose time between a predetermined time in the target time period and a start time of the vehicle use period is less than a third threshold, among the second candidate, as a third candidate for charging, when a predetermined condition based on at least the predicted remaining SOC of the vehicle as the second candidate is satisfied.

3. A method performed by an information processing apparatus, the method comprising:
for each of a plurality of vehicles for which charging in a target time period has been applied for, acquiring vehicle information including predicted remaining SOC (state of charge) to be remaining at a start of the target time period and/or predicted consumed SOC to be consumed in a vehicle use period after an end of the target time period;
determining, based on the vehicle information, whether each of the plurality of vehicles is eligible for charging in the target time period;
determining a charging plan to charge a vehicle being determined to be eligible for charging, among the plurality of vehicles, in the target time period;
acquiring supply power information including supply electrical energy to be supplied by a power supply facility for charging vehicles in the target time period;
determining whether charging electrical energy required to bring the predicted remaining SOC of all the plurality of vehicles to a predetermined charged state is less than or equal to the supply electrical energy; and
when it is determined that the charging electrical energy is greater than the supply electrical energy, determining a vehicle whose value subtracting the predicted consumed SOC from the predicted remaining SOC is greater than a reference value, among vehicles having not been determined to be eligible for charging, as a power feeding vehicle,
wherein the information processing apparatus is configured to determine a power feeding plan for the power feeding vehicle to feed power.
