Abstract

A battery selection device has a preparation amount information acquisition component, a supply amount information acquisition component, a battery candidate extraction component, and a determination processor. The preparation amount information acquisition component acquires preparation amount information indicating the scheduled date and time of a loan and the required charge amount. The supply amount information acquisition component acquires supply amount information indicating the full charge power capacity and the current charge amount of each battery. On the basis of the preparation amount information and the supply amount information, the battery candidate extraction component selects loaner battery candidates, which are batteries that can be charged to the required charge amount by the scheduled date and time of the loan. The determination processor picks out a loaner battery on the basis of the predicted progress of deterioration of batteries.

Claims

1. A battery selection device that selects which of a plurality of batteries in a charging station to charge at a time of selection, the battery selection device comprising:

a supply amount information acquisition component acquiring supply amount information including information about a full charge capacity and a remaining capacity at the time of selection for each of the plurality of batteries;

a battery extraction component extracting, as loaner battery candidates from the plurality of batteries, batteries having sufficient charge to be charged up to the preparation remaining capacity by the scheduled loan time, on the basis of the supply amount information and the preparation amount information; and

a determination component determining a loaner battery on the basis of a predicted progress of deterioration of batteries as a result of charging the loaner battery candidates up to the preparation remaining capacity by the scheduled loan time when there are a plurality of loaner battery candidates, and determine that loaner battery for charging.

2. The battery selection device according to claim 1,

wherein the plurality of batteries that are objects of selection do not include any batteries that have already been determined for charging in a previous selection at the scheduled loan time.

3. The battery selection device according to claim 1,

wherein the plurality of batteries that are objects of selection include a battery that has already been determined for charging in a previous selection at the scheduled loan time.

4. The battery selection device according to claim 1,

wherein the plurality of batteries that are objects of selection include a battery that has already been determined for charging in a previous selection at the scheduled loan time, and whose charging has already begun.

5. The battery selection device according to claim 3,

wherein the preparation amount information acquisition component acquires preparation amount information by taking over the preparation amount information for batteries that have already been determined for charging in a previous selection.

6. The battery selection device according to claim 3,

wherein the determination component discards this previous determination if a battery that has already been determined for charging in a previous selection is determined for charging.

7. The battery selection device according to claim 1,

wherein the battery extraction component outputs an error notification in an event that the loaner battery candidate is not extracted.

8. The battery selection device according to claim 1,

wherein the scheduled loan time includes a first scheduled loan time and a second scheduled loan time,

the preparation amount information acquisition component acquires, as the preparation amount information, first preparation amount information indicating a first preparation remaining capacity, which is the remaining capacity required for a first loaner battery when that battery is loaned out at the first scheduled loan time, and second preparation amount information indicating a second preparation remaining capacity, which is the remaining capacity required for a second loaner battery when that battery is loaned out at the second scheduled loan time,

the battery extraction component extracts, as loaner battery candidates from the plurality of batteries, a first loaner battery candidate that is a battery having sufficient charge to be charged up to the first preparation remaining capacity by the first scheduled loan time, and a second loaner battery candidate that is a battery having sufficient charge to be charged up to the second preparation remaining capacity by the second scheduled loan time, on the basis of the supply amount information and the preparation amount information, and

on the condition that the first loaner battery and the second loaner battery will be determined so as to be mutually different batteries, when there are a plurality of first loaner battery candidates, the determination component determines the first loaner battery on the basis of the predicted progress of deterioration of these first loaner battery candidates when they are charged up to the first preparation remaining capacity by the first scheduled loan time, and when there are a plurality of second loaner battery candidates, the determination component determines the second loaner battery on the basis of the predicted progress of deterioration of these second loaner battery candidates when they are charged up to the second preparation remaining capacity by the second scheduled loan time.
