Abstract

According to one exemplary embodiment, a charging/discharging determination apparatus includes: a receiving module which receives information of a rated capacity of a battery; and a determination module which determines that charging or a discharge of the battery is permitted if an absolute value of a difference between the rated capacity and a measured capacity which is an actual capacity of the battery is within a threshold value.

Claims

1. A charging/discharging determination apparatus comprising:

a receiving module configured to receive information of a rated capacity of a battery; and

a determination module configured to determine that charging or a discharge of the battery is permitted if an absolute value of a difference between the rated capacity and a measured capacity which is an actual capacity of the battery is within a threshold value.

2. The apparatus of claim 1, wherein the determination module is configured to determine that charging or a discharge of the battery is not permitted if the absolute value of the difference is not within the threshold value.

3. The apparatus of claim 2 further comprising:

a communication module configured to receive information of electric energy to be supplied from or stored in the battery, wherein;

the receiving module is configured to receive information of a State of Charge of the battery from the battery; and

the determination module is configured to determine that charging or a discharge of the battery is permitted if a predicted State of Charge which is calculated from the State of Charge and the electric energy is within a certain range.

4. The apparatus of claim 3, wherein the determination module is configured to determine that charging or a discharge of the battery is not permitted if the predicted State of Charge is not within the certain range.

5. The apparatus of claim 3, wherein the State of Charge of the battery is a State of Charge that is obtained before the charging/discharging determination apparatus is instructed to cause charging or a discharge of the battery.

6. The apparatus of claim 2, wherein the determination module is configured to determine whether or not the absolute value of the difference is within the threshold value when the battery is connected.

7. The apparatus of claim 1, wherein the determination module is configured to measure the measured capacity by discharging the battery after charging the battery completely or charging the battery after discharging the battery completely.

8. The apparatus of claim 3, wherein the certain range is an optimum State of Charge range for lifetime elongation of the battery.

9. The apparatus of claim 4, wherein the determination module is configured to measure the measured capacity by discharging the battery completely after charging the battery completely if the State of Charge is larger than a threshold value and by charging the battery completely after discharging the battery completely if the State of Charge is smaller than the threshold value.

10. The apparatus of claim 3, wherein the communication module is configured to receive the information of the electric energy based on a difference between a planned value and an actual value of power that is supplied from a power plant and a natural energy power generator.

11. A computer-readable non-transitory medium storing a charging/discharging determination program, the program comprising:

a receiving function of receiving information of a rated capacity from a battery; and

a determining function of determining that charging or a discharge of the battery is permitted if an absolute value of a difference between the rated capacity and a measured capacity which is an actual capacity of the battery is within a threshold value.
