Abstract

A power control device forms energy storage equipment together with a storage battery. The power control device includes: a communication portion that communicates with a power management device, which manages charge and discharge of the storage battery; a power conditioner that supplies electricity to a predetermined destination for supply; a control portion that controls operation of the power conditioner based on instructions from the power management device that are received by the communication portion; and an authentication processing portion that performs authentication processing with the power management device.

Claims

1. A power control device that, together with a storage battery, forms energy storage equipment, the power control device comprising:

a reception portion that receives instructions from a power management device that manages charge and discharge of the storage battery;

a power conditioner that supplies electricity to a predetermined destination for supply;

a control portion that controls operation of the power conditioner based on the instructions from the power management device;

a power determination portion that determines whether an amount of stored electricity in the storage battery and a supply power amount from the power conditioner to the storage battery satisfy predetermined conditions; and

a transmission portion that transmits, to the power management device, stored electricity amount information indicating the amount of stored electricity in the storage battery and determination result information indicating a determination result by the power determination portion.

2. The power control device according to claim 1, further comprising:

an encryption processing portion that encrypts the stored electricity amount information and the determination result information.

3. The power control device according to claim 1, further comprising:

a verification data generation portion that generates verification data used to verify whether the stored electricity amount information and the determination result information have been tampered with;

wherein the transmission portion transmits the verification data together with the stored electricity amount information and the determination result information.

4. A power management device comprising:

a reception portion that receives stored electricity amount information and determination result information transmitted from a power control device, the power control device forming energy storage equipment with a storage battery and the power control device including

a reception portion that receives instructions from the power management device that manages charge and discharge of the storage battery,

a power conditioner that supplies electricity to a predetermined destination for supply,

a control portion that controls operation of the power conditioner based on the instructions from the power management device,

a power determination portion that determines whether an amount of stored electricity in the storage battery and a supply power amount from the power conditioner to the storage battery satisfy predetermined conditions, and

a transmission portion that transmits, to the power management device, the stored electricity amount information indicating the amount of stored electricity in the storage battery and the determination result information indicating a determination result by the power determination portion; and

a point issuing portion that issues points with respect to each of the energy storage equipment in accordance with the amount of stored electricity indicated by the stored electricity amount information when the determination result information satisfies the predetermined conditions.

5. The power management device according to claim 4, further comprising:

at least one of a decryption processing portion and a verification processing portion, the decryption processing portion decrypting the stored electricity amount information and the determination result information that are encrypted and transmitted, and the verification processing portion verifying whether the stored electricity amount information and the determination result information have been tampered with, based on verification data that is transmitted together with the stored electricity amount information and the determination result information.
