Information processing device, information processing method, computer program product, and information processing system

An information processing method executed by an information processing device, the method comprising:

• calculating a ratio between an assembled battery capacity of an assembled battery in which a plurality of battery cells are serially connected and a cell capacity of a specific battery cell in the plurality of battery cells included in the assembled battery, as an index indicating a degree of collapse of a cell balance of the assembled battery.

A computer program product comprising a computer-readable medium including programmed instructions, the instructions causing a computer to execute:

• calculating a ratio between an assembled battery capacity of an assembled battery in which a plurality of battery cells are serially connected and a cell capacity of a specific battery cell in the plurality of battery cells included in the assembled battery, as an index indicating a degree of collapse of a cell balance of the assembled battery.

An information processing system comprising:

• an assembled battery including a plurality of battery cells connected serially;
• and
• one or more processors configured to calculate a ratio between an assembled battery capacity of the assembled battery and a cell capacity of a specific battery cell in the plurality of battery cells included in the assembled battery, as an index indicating a degree of collapse of a cell balance of the assembled battery.
