Abstract

Disclosed herein is a control apparatus, including: a discrimination section configured to discriminate a plurality of battery units which are to share and output electric power required by a load; and a control section configured to carry out discharge control for the battery units in response to a situation of each of batteries which the battery units individually have.

Claims

1. A control apparatus, comprising:

a discrimination section configured to discriminate a plurality of battery units which are to share and output electric power required by a load; and

a control section configured to carry out discharge control for the battery units in response to a situation of each of batteries which the battery units individually have.

2. The control apparatus according to claim 1, wherein the control section carries out the discharge control by determining a discharge amount for each of the battery units.

3. The control apparatus according to claim 2, wherein said control section determines a discharge amount for each of the battery units by setting a discharge period with respect to a reference signal.

4. The control apparatus according to claim 3, wherein a discharge period for which a predetermined one of the battery units is to carry out the discharge process and a discharge period for which another one of the battery units is to carry out the discharge process overlap with each other.

5. The control apparatus according to claim 1, wherein the situation of each of the batteries is at least one of a remaining capacity of the battery, a use history of the battery and a temperature of the battery.

6. The control apparatus according to claim 1, wherein the discrimination section successively connects the battery units to the load and monitors a voltage supplied from the connected one of the battery units to discriminate the battery unit.

7. A control method, comprising:

discriminating a plurality of battery units which are to share and output electric power required by a load; and

carrying out discharge control for the battery units in response to a situation of each of batteries which the battery units individually have.

8. A control system, comprising:

a plurality of battery units; and

a control apparatus connected to the battery units;

the control apparatus including

a discrimination section configured to discriminate a plurality of battery units which are to share and output electric power required by a load from among the battery units, and

a control section configured to carry out discharge control for the battery units in response to a situation of each of batteries which the battery units individually have.
