1. A management apparatus for an energy storage device, comprising a processor,
wherein the processor is, to determine an open circuit voltage (OCV) of the energy storage device, configured for:
after a start of counting an elapsed time since a current of the energy storage device becomes equal to or smaller than a first threshold, when a predetermined condition, in which a voltage of the energy storage device is possibly not stable even when the elapsed time reaches a stabilization time, is satisfied at a time point where the count reaches a predetermined value, the count of the elapsed time is changed, and
when the count of the elapsed time reaches the stabilization time, a voltage of the energy storage device measured after a lapse of the stabilization time is taken as the OCV.
