Abstract

According to one embodiment, a monitoring apparatus comprises a use history accumulating section, a demand prediction generating section, a power generation predicting section, a deterioration table determining section, a charge and discharge schedule creating section, and a transmission section. A use history accumulating section stores a use history of the battery. A deterioration table determining section configured to determine a deterioration table. A charge and discharge schedule creating section configured to create a charge and discharge schedule. A transmission section configured to transmit the demand prediction, the power generation prediction, the charge and discharge schedule, and the deterioration table.

First claim

What is claimed is:

1 . A monitoring apparatus comprising:
a controller configured to: receive at least battery condition information from a control apparatus that controls a power generating apparatus and a battery and to generate and to store a use history of the battery; generate a demand prediction for power consumed by a power consuming section for which power supply is controlled by the control apparatus; generate a power generation prediction for the power generating apparatus; determine a deterioration table indicative of a deterioration rate of the battery based on the use history; create a charge and discharge schedule for the battery based on the deterioration table, the demand prediction, and the power generation prediction; and transmit the demand prediction, the power generation prediction, the charge and discharge schedule, and the deterioration table allowing charge and discharge of the battery to be controlled.

2 . The monitoring apparatus according to claim 1 , wherein the controller configured further to:
set a term of validity to the deterioration table; and transmit the term of validity to the control apparatus.

3 . The monitoring apparatus according to claim 1 , wherein the controller configured to:
receive battery condition information corresponding to a period when the communication is disrupted from the control apparatus, when communication with the control apparatus is disrupted and then recovered; generate and stores the use history based on the battery condition information; determine the deterioration table based on the use history; and transmit the deterioration table to the control apparatus.

4 . The monitoring apparatus according to claim 2 , wherein the controller configured to:
receive battery condition information corresponding to a period when the communication is disrupted from the control apparatus, when communication with the control apparatus is disrupted and then recovered; generate and stores the use history based on the battery condition information; determine the deterioration table based on the use history; and transmit the deterioration table to the control apparatus.

5 . The monitoring apparatus according to claims 1 , wherein the deterioration table is indicative of the deterioration rate corresponding to a temperature and an SOC of the battery.

6 . The monitoring apparatus according to claims 2 , wherein the deterioration table is indicative of the deterioration rate corresponding to a temperature and an SOC of the battery.

7 . The monitoring apparatus according to claims 3 , wherein the deterioration table is indicative of the deterioration rate corresponding to a temperature and an SOC of the battery.

8 . The monitoring apparatus according to claims 4 , wherein the deterioration table is indicative of the deterioration rate corresponding to a temperature and an SOC of the battery.

9 . The monitoring apparatus according to claims 1 , wherein the deterioration table represents the deterioration rate as a binary value.

10 . A control apparatus configured to control a battery, a power generating apparatus, and a power consuming section, the control apparatus comprising:
a controller configured to: generate battery condition information on the battery; transmit the battery condition information to a monitoring apparatus; receive a demand prediction, a power generation prediction, a deterioration table, and a charge and discharge schedule from the monitoring apparatus; determine whether the demand prediction and the power generation prediction are equal to a power demand of the power consuming section and an amount of power generated by the power generating apparatus, respectively; control charge and discharge of the battery in accordance with the charge and discharge schedule when determining that the demand prediction and the power generation prediction are equal to the power demand of the power consuming section and the amount of power generated by the power generating apparatus, respectively; and control the charge and discharge of the battery based on the deterioration table when determining that the demand prediction and the power generation prediction are not equal to the power demand of the power consuming section and the amount of power generated by the power generating apparatus, respectively.

11 . The control apparatus according to claim 10 , further comprising:
a first recording section configured to pre-store a local deterioration table, wherein the controller configured to: receive a term of validity set to the deterioration table; determine whether the term of validity includes a current time; and controls the charge and discharge of the battery based on the deterioration table when determining that the term of validity includes the current time and controls the charge and discharge of the battery based on the local deterioration table when determining that the term of validity does not include the current time.

12 . The control apparatus according to claim 11 , further comprising:
a second recording section configured to store battery condition information generated by the battery condition measuring section when communication with the monitoring apparatus is disrupted, wherein the controller configured to: transmit the battery condition information to the monitoring apparatus when the communication with the monitoring apparatus is recovered.

13 . The control apparatus according to claims 10 , wherein the deterioration table is indicative of the deterioration rate corresponding to a temperature and an SOC of the battery.

14 . The control apparatus according to claims 11 , wherein the deterioration table is indicative of the deterioration rate corresponding to a temperature and an SOC of the battery.

15 . The control apparatus according to claims 12 , wherein the deterioration table is indicative of the deterioration rate corresponding to a temperature and an SOC of the battery.

16 . The monitoring apparatus according to claims 10 , wherein the deterioration table represents the deterioration rate as a binary value.

17 . A control system having a monitoring apparatus and a control apparatus,
the monitoring apparatus comprises: a first controller configured to: receive at least battery condition information from the control apparatus that controls a power generating apparatus and a battery and to generate and to store a use history of the battery; generate a demand prediction for power consumed by a power consuming section for which power supply is controlled by the control apparatus; generate a power generation prediction for the power generating apparatus; determine a deterioration table indicative of a deterioration rate of the battery based on the use history; create a charge and discharge schedule for the battery based on the deterioration table, the demand prediction, and the power generation prediction; and transmit the demand prediction, the power generation prediction, the charge and discharge schedule, and the deterioration table allowing charge and discharge of the battery to be controlled, and the control apparatus comprises: a first controller configured to: generate battery condition information on the battery; transmit the battery condition information to the monitoring apparatus; receive the demand prediction, the power generation prediction, the deterioration table, and the charge and discharge schedule from the monitoring apparatus; determine whether the demand prediction and the power generation predi
