- a processor, and a non-transitory computer-readable memory having stored therein a program to be executed by the processor causing the vehicle charger, including the processor and memory, to function as;
a calculation unit configured to calculate, for each combination of a request amount and an allowable time, a total amount of a power price and a parking fee, the power price being a product of a set unit price and the request amount, the parking fee being a fee for parking of a vehicle, of the vehicles, at the charging station for the allowable time;
a power charging information presentation unit configured to display, to respective users of each of the vehicles, a first screen showing information indicating the total amounts calculated by the calculation unit and a unit price table in which (i) unit prices of charging power, (ii) request amounts of the charging power, and (iii) allowable times are arranged in a matrix, wherein each combination of the request amounts and allowable times is associated with a corresponding one of the unit prices, wherein each allowable time is an amount of time that a user, of the users, agrees to allow for charging to be completed, and wherein for each request amount in the unit price table, the unit price is lower the longer the associated allowable time is, and for each allowable time in the unit price table, the unit price is lower the smaller the associated requested amount is;
a power charging request receiving unit configured to receive power charging requests from the users, each of the power charging requests specifying a request amount of the charging power and an allowable time for charging;
a determination unit configured to determine, with reference to the unit price table, whether or not there is another allowable time which is associated with the request amount specified in the power charging request and meets a first condition that (i) the other allowable time is longer than the allowable time specified in the power charging request and (ii) the unit price associated with the other allowable time is lower than the unit price associated with the request amount and the allowable time specified in the power charging request,wherein when the determination unit determines that there is the other allowable time which meets the first condition, the power charging information presentation unit is further configured to change the first screen showing the unit price table into a second screen including the other allowable time which meets the first condition and the unit price associated with the other allowable time which meets the first condition;
a priority calculation unit configured to determine a priority order of charging of the vehicles by prioritizing the charging requests associated with the vehicles according to a proportion of allowable time per requested amount;
a power receiving unit, connected to a power source, configured to selectively draw power from the power source; and
a power charging control unit configured to;
control the power receiving unit to cause the power receiving unit to draw power from the power source; and
direct the power to the vehicles in order according to the calculated priority order.

Abstract
A vehicle charging control apparatus includes: a unit which presents unit prices of charging power; a unit which issues an instruction for preferentially charging a vehicle for which allowable time is short in proportion to request amount; and a unit which determines whether there is another allowable time which is associated with the request amount and meets a condition that the other allowable time is longer than the allowable time and the unit price associated with the other allowable time is lower than the unit price associated with the request amount and the allowable time. The unit prices are set lower when associated with a longer allowable time and also set lower when associated with a smaller request amount. When the other allowable time meets the condition, the other allowable time and the unit price associated with the other allowable time are presented.

10. A vehicle charging method of charging a plurality of vehicles parked at a charging station, comprising:
-
calculating, for each combination of a request amount and an allowable time, a total amount of a power price and a parking fee, the power price being a product of a set unit price and the request amount, the parking fee being a fee for parking of a vehicle, of the plurality of vehicles, at the charging station for the allowable time; displaying, to respective users of each of the plurality of vehicles, a first screen showing information indicating the total amounts calculated in the calculating and a unit price table in which (i) unit prices of charging power, (ii) request amounts of the charging power, and (iii) allowable times are arranged in a matrix, wherein each combination of the request amounts and allowable times is associated with a corresponding one of the unit prices, wherein each allowable time is an amount of time that a user, of the users, agrees to allow for charging to be completed, and wherein for each request amount in the unit price table, the unit price is lower the longer the associated allowable time is, and for each allowable time in the unit price table, the unit price is lower the smaller the associated requested amount is; receiving power charging requests from the users, each of the power charging requests specifying a request amount of the charging power and an allowable time for the charging; determining, with reference to the unit price table, whether or not there is another allowable time which is associated with the request amount specified in the power charging request and meets a first condition that (i) the other allowable time is longer than the allowable time specified in the power charging request and (ii) the unit price associated with the other allowable time is lower than the unit price associated with the request amount and the allowable time specified in the power charging request, wherein when it is determined in the determining that there is the other allowable time which meets the first condition, in the displaying, changing the first screen showing the unit price table into a second screen including the other allowable time which meets the first condition; determining a priority order of charging of the plurality of vehicles by prioritizing the charging requests associated with the plurality of vehicles according to a proportion of allowable time per requested amount; and automatically controlling a power receiving unit to cause the power receiving unit to draw power from a power source, and directing the power to the plurality of vehicles in order according to the calculated priority order.
