Management device, energy storage module, management method, and computer program

A computer-implemented management method comprising:

• resting an energization of an energy storage device via a processor or an electronic controller and based upon a measurement result of a current measuring unit;
• acquiring, via the processor and based on measurement results obtained by a voltage measurement unit and the current measuring unit, a change amount between a voltage of the energy storage device when the energization is rested from a state in which the energy storage device is energized and a voltage when a period elapses;
• and
• determining, via the processor, whether the change amount is included in a second range corresponding to a first range where a difference in voltage between a storage amount-voltage characteristic during charge and a storage amount-voltage characteristic during discharge with respect to an identical storage amount is smaller than a hysteresis range.

A computer program product comprising a non-transitory computer-readable medium having computer program instructions stored therein, the computer program instructions, when executed by a processor, causing the processor to:

• resting, directly or via an electronic controller and based upon a measurement result of a current measuring unit, an energization of an energy storage device;
• acquiring a change amount between a voltage of the energy storage device when the energization is rested from a state in which the energy storage device is energized and a voltage when a period elapses;
• and
• determining whether the change amount is included in a second range corresponding to a first range where a difference in voltage between a storage amount-voltage characteristic during charge and a storage amount-voltage characteristic during discharge with respect to an identical storage amount is smaller than a hysteresis range.
