no. 1 approach

[0028] Below, while referring to the attached Figure 1 The first embodiment will be described.

[0029] The deterioration amount control system of the first embodiment controls the amount of deterioration (or battery consumption) of the storage battery. The degradation amount monitoring device generates a charge / discharge schedule of the storage battery, etc. based on the information of the storage battery transmitted from the degradation amount control device. The deterioration amount control device controls charge and discharge of the storage battery in accordance with the charge and discharge schedule generated by the deterioration amount monitoring device and the like. In addition, the storage battery includes a plurality of battery cells.

[0030] In addition, the deterioration amount control device controls electric power supplied to electric power consumption units such as individual houses or factories. That is, the degradation amount control device supplies electr...

no. 2 approach

[0128] Next, the degradation amount control system of the second embodiment will be described.

[0129] Figure 9 It is a block diagram showing a functional example of the deterioration amount control system 1 of the second embodiment.

[0130] The functional example of the degradation amount control system 1 of the second embodiment differs from the functional example of the degradation amount control system 1 of the first embodiment in that the degradation table determination unit 12 includes an expiration date setting unit 12a, and a degradation amount control device. 20 includes an expiration date determination unit 24 . Therefore, the same reference numerals are assigned to other parts and detailed descriptions are omitted.

[0131] The expiration date setting unit 12 a included in the degradation table determination unit 12 sets an expiration date for the degradation table determined by the degradation table determination unit 12 . The expiration date indicates the pe...

no. 3 approach

[0159] Next, a third embodiment will be described.

[0160] Figure 12 It is a block diagram showing a functional example of the degradation amount control system 1 of the third embodiment.

[0161] The functional example of the degradation amount control system 1 of the third embodiment differs from the functional example of the degradation amount control system 1 of the second embodiment in that the degradation amount control device 20 includes a battery state recording unit 25 . Therefore, the same reference numerals are assigned to other points, and detailed descriptions are omitted.

[0162] The battery state recording unit 25 stores the battery state information generated by the battery state measuring unit 21 when the communication with the deterioration amount monitoring device 10 is cut off. The battery state recording unit 25 additionally continues to store the battery state information generated by the battery state measuring unit 21 while the communication with t...

Abstract

Provided are a monitoring device, a control device and a control system with which charging / discharging of a storage battery can be effectively controlled. A monitoring device according to an embodiment of the present invention includes a use history accumulation unit, a demand prediction generation unit, a power generation prediction unit, a deterioration table determination unit, a charging / discharging plan creation unit and a transmission unit. The use history accumulation unit receives at least storage battery state information from the control device that controls a power generation device and a storage battery, and generates and then stores the use history of the storage battery. The demand prediction generation unit generates a demand prediction for power consumption of a power consumption unit to which supply of power is controlled by the control device. The power generation prediction unit generates a power generation prediction for the power generation device. The deterioration table determination unit determines a deterioration table that indicates a deterioration rate of the storage battery from the use history. The charging / discharging plan creation unit creates a charging / discharging plan for the storage battery on the basis of the deterioration table, the demand prediction and the power generation prediction. The transmission unit transmits to the control device the demand prediction, the power generation prediction, the charging / discharging plan and the deterioration table which is for controlling charging / discharging of the storage battery.

Description

technical field [0001] Embodiments of the present invention relate to a monitoring device, a control device, and a control system. Background technique [0002] The degradation amount control device that controls the degradation amount (battery consumption) of the storage battery receives a charging and discharging schedule from the degradation monitoring device as a host device, and charges and discharges the storage battery in accordance with the received charging and discharging schedule. However, in the past, when the demand forecast, which is the basis of the charge-discharge plan, etc. is different from reality, and the deterioration amount cannot be appropriately controlled if the charge-discharge plan is carried out as in the charge-discharge plan, there are cases where the deterioration amount control device cannot properly control the storage battery. The subject of charging and discharging. [0003] prior art literature [0004] patent documents [0005] Patent...
