Abstract
When a temperature Tedge of a cell at an end of a battery pack is higher than a temperature Tcen of a cell in a pack central portion, a management server generates rebuilding information for rebuilding a battery pack such that a cell less likely to deteriorate than a cell arranged in the pack central portion is arranged at a pack end. When temperature Tcen is higher than temperature Tedge, the management server generates rebuilding information such that a cell less likely to deteriorate than a cell arranged at the pack end is arranged in the pack central portion.
Claims1
A method of manufacturing a battery assembly including a plurality of cells, the method comprising:
- obtaining replacement information for manufacturing the battery assembly by replacing at least some of the plurality of cells with replacement cells;
- and
- manufacturing the battery assembly by using replacement cells selected in accordance with the obtained replacement information,
- the replacement information being information generated by using a first temperature history and a second temperature history, the first temperature history representing a temperature history of a cell arranged in vicinity of an outer periphery of the battery assembly, the second temperature history representing a temperature history of a cell arranged in a central portion of the battery assembly, and
- the replacement information
- indicating that a first replacement cell is to be selected and arranged in the vicinity of the outer periphery of the battery assembly when a first temperature indicating an index of the first temperature history is higher than a second temperature indicating an index of the second temperature history, the first replacement cell being determined as being less likely to deteriorate than a cell arranged in the central portion of the battery assembly based on a prescribed indicator indicating less likeliness of deterioration of a cell, and
- indicating that a second replacement cell is to be selected and arranged in the central portion of the battery assembly when the second temperature is higher than the first temperature, the second replacement cell being determined as being less likely to deteriorate than a cell arranged in the vicinity of the outer periphery of the battery assembly based on the indicator.
