Abstract

An acquisition unit acquires state of health of a storage battery provided to supply electric power, in which the state of health shows a smaller value as the storage battery deteriorates. A display unit performs notification when state of health acquired by the acquisition unit is smaller than a first threshold value. When the acquisition unit has not acquired state of health for a predetermined period, the display unit performs notification if the elapsed period from the manufacture of the storage battery is longer than a second threshold value.

Claims

1. A control apparatus, comprising:

an acquisition unit that acquires state of health of a storage battery provided to supply electric power to a load, the state of health showing a smaller value as the storage battery deteriorates; and

a notification unit that performs notification when state of health acquired by the acquisition unit is smaller than a first threshold value, wherein,

when the acquisition unit has not acquired state of health for a predetermined period, the notification unit performs notification if the elapsed period from the manufacture of the storage battery is longer than a second threshold value.

2. The control apparatus of claim 1, wherein, when state of health smaller than the first threshold value becomes even smaller, the notification unit changes the mode of notification.

3. The control apparatus of claim 2, wherein the notification unit increases the frequency of notification as the state of health becomes smaller.

4. The control apparatus of claim 1, wherein, when an elapsed period longer than the second threshold value becomes even longer, the notification unit changes the mode of notification.

5. The control apparatus of claim 4, further comprising a processing unit that stops charging and discharging of the storage battery, wherein

the processing unit stops charging and discharging of the storage battery when the notification unit has changed the mode of notification.

6. The control apparatus of claim 4, wherein the notification unit increases the frequency of notification as the elapsed period becomes longer.

7. The control apparatus of claim 1, wherein the notification unit changes the mode of notification according to whether the state of health acquired by the acquisition unit is smaller than the first threshold value or the elapsed period from the manufacture of the storage battery is longer than the second threshold value.

8. The control apparatus of claim 7, further comprising a processing unit that stops charging and discharging of the storage battery, wherein

the processing unit stops charging and discharging of the storage battery when the notification unit has changed the mode of notification.

9. The control apparatus of claim 1, wherein the acquisition unit acquires state of health of a storage battery provided to supply electric power to a load in the case where a commercial power supply fails.

10. A control method, comprising:

acquiring state of health of a storage battery provided to supply electric power to a load, the state of health showing a smaller value as the storage battery deteriorates; and

performing notification when acquired state of health is smaller than a first threshold value, wherein,

when state of health has not been acquired for a predetermined period in the acquiring, notification is performed in the performing notification if the elapsed period from the manufacture of the storage battery is longer than a second threshold value.
