1. An in-vehicle battery management device comprising:
a controller configured or programmed to control a charge/discharge device such that the charge/discharge device performs charge or discharge on an in-vehicle battery of an electric vehicle in a predetermined processing condition, the in-vehicle battery being connected to the charge/discharge device, wherein
in the electric vehicle, a degree of deterioration progress is calculated, and
the controller comprises:
a calculator configured or programmed to calculate a degree of deterioration progress of the in-vehicle battery based on charge/discharge information in the charge or discharge;
a communicator configured or programmed to notify a predetermined notification target of the calculated degree of deterioration progress;
an acquirer configured or programmed to acquire the degree of deterioration progress calculated in the electric vehicle; and
a first determiner configured or programmed to determine whether at least one of the degree of deterioration progress acquired from the electric vehicle or the degree of deterioration progress calculated based on the charge/discharge information is less than or equal to a predetermined value, wherein
the communicator configured or programmed to notify the predetermined notification target of the degree of deterioration progress if at least one of the degree of deterioration progress acquired from the electric vehicle or the degree of deterioration progress calculated based on the charge/discharge information is less than or equal to a predetermined value.
