Abstract

A storage cell management apparatus includes a power conversion unit, a determination unit, an allocation setting unit and a distribution unit. The power conversion unit is configured to perform an operation of storing power in a storage cell and an operation of discharging power from the storage cell. The determination unit is configured to determine an application of power discharged from the storage cell as one of a plurality of applications. The allocation setting unit is configured to determine an upper limit of an amount of power that can be supplied to each application, using a distribution ratio determined for the plurality of applications. The distribution unit is configured to supply the power stored in the storage cell for the application determined by the determination unit, with the power not exceeding the upper limit determined by the allocation setting unit for the application.

Claims

1. A storage cell management apparatus, comprising:

a power conversion unit configured to perform an operation of storing power in a storage cell and an operation of discharging power from the storage cell;

a determination unit configured to determine an application of power discharged from the storage cell as one of a plurality of application

an allocation setting unit configured to determine an upper limit of an amount of power that can be supplied to each of the plurality of applications, using a distribution ratio determined for the plurality of applications;

a distribution unit configured to supply the power stored in the storage cell for the application determined by the determination unit, with the power not exceeding the upper limit determined by the allocation setting unit for the application;

an acquisition unit configured to acquire warning information relating to disaster prevention; and

a period setting unit configured to determine a response period to respond to the warning information,

wherein the allocation setting unit is configured to change the distribution ratio, depending on whether the period is the response period or not,

wherein the plurality of applications comprise;

a first application of supplying power from the storage cell to an electric load of a facility when power supply from a power system stops; and

a second application of supplying power from the storage cell to the electric load so as to decrease the amount of power, which the facility receives from the power system,

wherein the acquisition unit is configured to acquire the warning information for each region to which an electric utility supplies power, and

wherein in a region of interest, which is a target of the warning information, the allocation setting unit is configured to set the distribution ratio of the first application to be higher in the response period than in a period other than the response period, and set the distribution ratio of the second application to be lower in the response period than in a period other than the response period.

6. The storage cell management apparatus according to claim 1, wherein the storage cell is installed in an electric vehicle.

7. The storage cell management apparatus according to claim 1,

wherein the storage cell is installed in an electric vehicle, and

wherein the plurality of applications further comprise a third application of discharging power used for running of the electric vehicle.

2. (canceled)

3. (canceled)

5. The storage cell management apparatus according to claim 3,

wherein the acquisition unit is configured to acquire the warning information for each region to which the electric utility supplies power, and

wherein in an external region which is not the target of the warning information, the allocation setting unit is configured to set the distribution ratio of the first application to be lower in the response period than in a period other than the response period, and set the distribution ratio of the second application to be higher in the response period than in a period other than the response period.

8. The storage cell management apparatus according to claim 5, wherein the storage cell is installed in an electric vehicle.

9. The storage cell management apparatus according to claim 5,

wherein the storage cell is installed in an electric vehicle, and

wherein the plurality of applications further comprise a third application of discharging power used for running of the electric vehicle.

4. (canceled)
