Abstract

A charging control apparatus includes a battery, an electric charge mover, and a processor. The battery includes multiple cells. The electric charge mover is configured to move electric charge between the multiple cells. The processor is configured to, upon charging the battery, cause the electric charge mover to move the electric charge of one or more cells serving as a part of the multiple cells to another one or more cells of the multiple cells, and perform a partial charging that charges the one or more cells serving as the part of the multiple cells after causing the electric charge mover to move the electric charge.

First claim

The invention claimed is:

1. A charging control apparatus comprising:
a battery including multiple cells;
an electric charge mover configured to move electric charge among the cells; and
a processor configured to, upon charging the battery, cause the electric charge mover to move the electric charge of one or more cells serving as a part of the multiple cells to another one or more cells of the multiple cells, and perform a partial charging that charges the one or more cells serving as the part of the multiple cells after causing the electric charge mover to move the electric charge.

2. The charging control apparatus according to claim 1 , wherein the processor is configured to perform any of a regular charging and the partial charging on a basis of a predetermined condition, the regular charging being configured to charge the multiple cells.

3. The charging control apparatus according to claim 2 , wherein the processor is configured to perform any of the regular charging and the partial charging, on a basis of a standby time, a charging possible time, and a charging rate of the battery, the standby time being a time until which the charging of the battery is started, the charging possible time being a time during which performing the charging of the battery is possible.

4. The charging control apparatus according to claim 1 , wherein the processor is configured to perform a cell balancing of the multiple cells after performing the partial charging.

5. The charging control apparatus according to claim 2 , wherein the processor is configured to perform a cell balancing of the multiple cells after performing the partial charging.

6. The charging control apparatus according to claim 3 , wherein the processor is configured to perform a cell balancing of the multiple cells after performing the partial charging.

7. The charging control apparatus according to claim 1 , wherein
each of the multiple cells is set in advance to any of a first cell and a second cell, and
the processor is configured to cause the electric charge of one or more first cells to be moved to one or more second cells, and charge the one or more first cells upon the partial charging after causing the electric charge of the one or more first cells to be moved to the one or more second cells.

8. The charging control apparatus according to claim 2 , wherein
each of the multiple cells is set in advance to any of a first cell and a second cell, and
the processor is configured to cause the electric charge of one or more first cells to be moved to one or more second cells, and charge the one or more first cells upon the partial charging after causing the electric charge of the one or more first cells to be moved to the one or more second cells.

9. The charging control apparatus according to claim 3 , wherein
each of the multiple cells is set in advance to any of a first cell and a second cell, and
the processor is configured to cause the electric charge of one or more first cells to be moved to one or more second cells, and charge the one or more first cells upon the partial charging after causing the electric charge of the one or more first cells to be moved to the one or more second cells.

10. The charging control apparatus according to claim 4 , wherein
each of the multiple cells is set in advance to any of a first cell and a second cell, and
the processor is configured to cause the electric charge of one or more first cells to be moved to one or more second cells, and charge the one or more first cells upon the partial charging after causing the electric charge of the one or more first cells to be moved to the one or more second cells.

11. The charging control apparatus according to claim 5 , wherein
each of the multiple cells is set in advance to any of a first cell and a second cell, and
the processor is configured to cause the electric charge of one or more first cells to be moved to one or more second cells, and charge the one or more first cells upon the partial charging after causing the electric charge of the one or more first cells to be moved to the one or more second cells.

12. The charging control apparatus according to claim 6 , wherein
each of the multiple cells is set in advance to any of a first cell and a second cell, and
the processor is configured to cause the electric charge of one or more first cells to be moved to one or more second cells, and charge the one or more first cells upon the partial charging after causing the electric charge of the one or more first cells to be moved to the one or more second cells.
