Abstract
When ΔSOC (an amount of variation in SOC per one running) is greater than a second threshold value, a management server generates third rebuilding information indicating that a cell is a suited cell. When ΔSOC is greater than a first threshold value and smaller than the second threshold value, the management server generates second rebuilding information indicating that a cell is a suited cell. When ΔSOC is smaller than the first threshold value, the management server generates first rebuilding information indicating that a cell is a suited cell.
Claims11
A battery information processing apparatus which processes information for manufacturing a battery assembly including a plurality of cells, the battery information processing apparatus comprising:
- a battery information obtaining device configured to obtain an amount of variation in SOC per one running of the battery assembly used in a vehicle;
- and
- a replacement information generator configured to generate replacement information for selecting a suited cell suited to replacement of a cell included in the battery assembly from among replacement cells by using the amount of variation in SOC, the replacement cells being replacable with the cell,
- the replacement information generator being configured to
- generate first replacement information when the amount of variation in SOC is smaller than a first threshold value, and
- generate second replacement information when the amount of variation in SOC is greater than the first threshold value,
- the first replacement information indicating that a first cell is the suited cell, and
- the second replacement information indicating that a second cell is the suited cell, the second cell being determined as being less likely to deteriorate than the first cell based on a prescribed indicator, the prescribed indicator indicating less likeliness of deterioration of a cell.
A battery information processing method of processing information for manufacturing a battery assembly including a plurality of cells, the battery information processing method comprising:
- obtaining an amount of variation in SOC per one running of the battery assembly used in a vehicle;
- and
- generating replacement information for selecting a suited cell suited to replacement of a cell included in the battery assembly from among replacement cells by using the amount of variation in SOC, the replacement cells being replacable with the cell,
- the generating replacement information including
- comparing the amount of variation in SOC with a first threshold value,
- generating first replacement information when the amount of variation in SOC is smaller than the first threshold value, and
- generating second replacement information when the amount of variation in SOC is greater than the first threshold value,
- the first replacement information indicating that a first cell is the suited cell, and
- the second replacement information indicating that a second cell is the suited cell, the second cell being determined as being less likely to deteriorate than the first cell based on a prescribed indicator, the prescribed indicator indicating less likeliness of deterioration of a cell.
A method of manufacturing a battery assembly including a plurality of cells, the method comprising:
- obtaining replacement information for selecting a suited cell suited to replacement of a cell included in the battery assembly from among replacement cells, the replacement cells being replacable with the cell;
- and
- manufacturing the battery assembly by using the suited cell selected in accordance with the obtained replacement information,
- the replacement information being information generated by using an amount of variation in SOC per one running of the battery assembly used in a vehicle,
- the replacement information indicating that
- a first cell is the suited cell when the amount of variation in SOC is smaller than a first threshold value, and
- a second cell is the suited cell when the amount of variation in SOC is greater than the first threshold value, the second cell being determined as being less likely to deteriorate than the first cell based on a prescribed indicator, the prescribed indicator indicating less likeliness of deterioration of a cell.
