Charge-discharge management apparatus and system for vehicle

1. A charge-discharge management system for a vehicle that runs using electricity stored in a battery, the charge-discharge management system comprising:

a charge-discharge schedule creation unit configured to create a charge-discharge schedule of the battery for a travel route of the vehicle according to the travel route of the vehicle and a condition of at least one of the vehicle and a road, so that a charge amount of the battery falls within a predetermined range in the travel route;

a charge-discharge schedule correction unit configured to

divide the travel route into a plurality of sections,

make a comparison between the charge amount actually in the battery and the charge amount in the charge-discharge schedule at every section of the plurality of sections, thereby providing a result of the comparison, and

correct the charge-discharge schedule for subsequent sections according to the result of the comparison, wherein the subsequent sections are sections subsequent to where the comparison is made;

a charge-discharge schedule re-creation unit configured to re-create the charge-discharge schedule in response to an occurrence of a change in a via-point of the travel route or a change in the amount of load carried by the vehicle when the vehicle is traveling along the travel route; and

a management device configured to:

propose a plurality of additional electric power consumption ways to a user of the vehicle when an over-charged point, at which the battery is to be over-charged, is present in the re-created charge-discharge schedule;

add to the re-created charge-discharge schedule an additional electric power consumption way that is selected by the user of the vehicle from the plurality of proposed additional electric power consumption ways;

propose a plurality of additional electric power charging ways to the user of the vehicle when an over-discharged point, at which the battery is to be over-charged, is present in the re-created charge-discharge schedule; and

add to the re-created charge-discharge schedule an additional electric power charging way that is selected by the user of the vehicle from the plurality of proposed additional electric power charging ways,

wherein electric power transmission to or charging from an infrastructure external to the vehicle is addable to the charge-discharge schedule.

2. The charge-discharge management system according to claim 1 , wherein:

the condition of the vehicle includes an amount of load carried by the vehicle.

3. The charge-discharge management system according to claim 1 , wherein:

the condition of the road includes at least one of: uphill and downhill of the road; unevenness of the road; and curvature radius of the road.

4. The charge-discharge management system according to claim 1 , further comprising:

an in-vehicle energy storage device configured to perform a cooling storage operation or a heating operation with respect to the electricity stored in the battery,

wherein:

when the charge amount actually in the battery is larger than the charge amount in the charge-discharge schedule, the in-vehicle energy storing device performs the cooling storage operation or the heating operation.

5. The charge-discharge management system according to claim 1 , further comprising:

a wireless electric power transmission reception device configured to wirelessly transmit electric power to outside of the vehicle or wirelessly receive electric power from outside of the vehicle, for keeping the charge amount of the battery within the predetermined range in the travel route.

6. A charge-discharge management apparatus mounted to a commercial vehicle that travels using electricity stored in a battery of the commercial vehicle, the charge-discharge management apparatus comprising:

a communication device configured to communicate with a center to receive information on a business schedule indicating a travel route of the vehicle for transportation of goods;

a charge-discharge schedule creation device configured to create a charge-discharge schedule of the battery for the travel route of the commercial vehicle according to the business schedule and a condition of at least one of the commercial vehicle and a road, wherein the charge-discharge schedule is a schedule for charging and discharging the battery to keep a charge amount of the battery within a predetermined range all along the travel route;

a charge-discharge schedule correction device configured to correct the charge-discharge schedule correction by

dividing the travel route into a plurality of sections,

making a comparison between the charge amount actually in the battery and the charge amount in the charge-discharge schedule at every section of the plurality of sections, thereby providing a result of the comparison, and

correcting the charge-discharge schedule for subsequent sections according to the result of the comparison, the subsequent sections being sections subsequent to where the comparison is made; and

a charge-discharge schedule re-creation device configured to re-create the charge-discharge schedule in response to a change in the business schedule when the commercial vehicle is traveling along the travel route; and

a management device configured to:

propose a plurality of additional electric power consumption ways to a user of the commercial vehicle when an over-charged point, at which the battery is to be over-charged, is present in the re-created charge-discharge schedule;

add to the re-created charge-discharge schedule an additional electric power consumption way that is selected by the user of the commercial vehicle from the plurality of proposed additional electric power consumption ways;

propose a plurality of additional electric power charge ways to the user of the commercial vehicle when an over-discharged point, at which the battery is to be over-charged, is present in the re-created charge-discharge schedule; and

add to the re-created charge-discharge schedule an additional electric power charge way that is selected by the user of the commercial vehicle from the plurality of proposed additional electric power charge ways,

wherein:

electric power transmission to or charging from an infrastructure external to the vehicle is addable to the charge-discharge schedule;

the condition of the commercial vehicle includes an amount of load carried by the commercial vehicle; and

the condition of the road includes at least one of: uphill and downhill of the road; unevenness of the road; and curvature radius of the road.
